# Flying United Airlines with Kids: Bassinets, Family Boarding & Car Seat Rules

**Quick Answer**: Per United Airlines' published policy, the Economy bassinet cap is 15.8 kg / 35 lb — the global industry's highest — with a DOT ✅ adjacent-seating commitment for children ≤14.

**TL;DR**: Per United Airlines' published policy, the carrier leads the US big-three on two headline metrics: an industry-highest 15.8 kg / 35 lb Economy bassinet wall-mount cap on its wide-body international fleet, and a DOT Family Seating Dashboard ✅ commitment guaranteeing fee-free adjacent seating for children ≤14. The trade-offs are real: international lap-infant additions require a phone call, the USD 150 UM fee is the highest among US legacies after Alaska, and United Express regional-jet connections often return strollers at the carousel rather than the jet bridge.

## Family Boarding
- **Available**: Yes
- **Boarding Zone**: Group 1.5
- **Age Eligibility**: Children under 2 years old; also applicable to passengers carrying strollers or car seats

Per United Airlines' published policy, passengers traveling with children under 2 years old, or with strollers and car seats, board in what United designates as Group 1.5 — after Premier 1K and Global Services elite members, but before Groups 2 through 5. No additional fee applies.

## Stroller & Car Seat
Per United Airlines' published policy, one stroller and one car seat per child may be checked free of charge at the gate or ticket counter. The gate-check weight limit for strollers is 20 lbs / 9 kg; heavier or oversized strollers must be checked at the ticket counter.

- **Standard Stroller** — Fee: Free, Check at: Gate or counter, Size: Up to 20 lbs / 9 kg for gate check; larger accepted at counter. Mainline 777/787/737 MAX 9 flights return strollers at the jet bridge; United Express CRJ-200/E145/E175 regional flights typically return at baggage carousel.
- **Car Seat** — Fee: Free, Check at: Gate or counter, Size: FAA-approved sticker required for in-cabin use. Per United Airlines' published policy, FAA-approved car seats may be used in a purchased seat in-cabin; seats without the FAA sticker are gate-checked to cargo.
- **Booster Seat** — Fee: Free, Check at: Gate or counter, Size: Treated as child safety equipment. Backless and high-back boosters without an integrated harness are not FAA-approved for in-cabin use — check to cargo; only harness-equipped FAA-approved seats may be used in-cabin.
- **Pack-n-Play / Travel Crib** — Fee: Counts as one checked bag, Check at: Counter only, Size: Standard checked-bag dimensions apply. Per United Airlines' published baggage policy, a pack-n-play or portable crib counts against the passenger's checked-bag allowance and any applicable fees; it is not treated as free child equipment.

## Baggage by Age
- **Lap Infant (Under 2, no seat purchased)** — Carry-on: None — shares parent's carry-on allowance; diaper bag is free extra; Checked: 1 free checked bag up to 10 kg on international routes; domestic gear-only; Personal: Diaper bag (free, exempt from parent's personal item count). Per United Airlines' published policy, the lap-infant free international bag must be within standard weight and size limits. Stroller and car seat are free in addition to any checked baggage.
- **Infant with Seat (Under 2, seat purchased)** — Carry-on: Same as adult ticket for the applicable fare class; Checked: Same as adult ticket for the applicable fare class; Personal: 1 personal item plus free diaper bag. A purchased seat grants the infant the full adult baggage allowance at the purchased fare class. Car seat may be used in-cabin if FAA-approved.
- **Child 2+ (Adult Fare Required)** — Carry-on: Same as adult ticket for the applicable fare class; Checked: Same as adult ticket; standard checked-bag fees apply if not included; Personal: 1 personal item. Per United Airlines' published policy, children 2 and older pay the adult fare at the same fare class as the accompanying adult. No child-specific baggage discount applies.

## Bassinet & Onboard
- **Bassinet Available**: Yes
- **Weight Limit**: Economy wall-mount up to 15.8 kg / 35 lb; Polaris fixed up to 11.3 kg / 25 lb
- **Age Limit**: Generally under 12 months; verify with United based on the infant's weight
- **Fee**: Free — bulkhead Economy Plus seat for parent may require upgrade fee; bassinet itself is free

Per United Airlines' published policy, bassinets are available on the 757-200/-300, 767-300ER/400, 777-200/300ER, and 787-8/9/10 international fleet. The Economy wall-mount cap of 15.8 kg / 35 lb is the highest in the global airline industry; Polaris business-class fixed bassinets cap at 11.3 kg / 25 lb. Families may pre-reserve a bulkhead bassinet seat by calling United Reservations.

## Child Fare
- **No child discount**

Per United Airlines' published policy, per United Airlines' published policy, the airline does not offer a published child fare discount for passengers aged 2 and older. This is standard across all five US-legacy carriers — Delta, American, United, Alaska, and Hawaiian — and contrasts with several European and Asian carriers. For example, per Lufthansa's published policy, children receive a percentage discount on international fares; per All Nippon Airways' published policy, children under 12 receive a domestic discount. US parents planning a large family trip on United should budget for full adult fares for every child 2 and older. The one cost lever available is the lap-infant rate for children still under 24 months at time of travel.

## Unaccompanied Minor
- **Available**: Yes
- **Fee**: USD 150 each way per child

Per United Airlines' published policy, unaccompanied minor (UM) service is mandatory for children ages 5–14 traveling alone on United-operated flights. The fee is USD 150 each way per child. Children ages 5–7 are restricted to non-stop flights; children ages 8–14 may connect on United-operated metal only. Booking must be completed by phone through United Reservations.

## Industry Comparison
### How United Airlines stacks up for family travel in 2026

Among the US big-three legacy carriers, United Airlines holds the highest overall family-travel score at 6.5, per the Velivolo research dataset — ahead of American Airlines (6.4) and Delta Air Lines (6.1). The gap is anchored by two differentiators.

The most significant is the bassinet weight ceiling. Per United Airlines' published policy, the Economy wall-mount bassinet cap on the 777/787/767 international fleet reaches 15.8 kg / 35 lb. Per Singapore Airlines' published policy, Singapore's bassinet cap is 14 kg / 30.8 lb. Per Emirates' published policy, the Emirates bassinet cap is 11 kg. United's 15.8 kg ceiling leads the global 28-airline set and gives parents of older-but-still-young infants an option most long-haul carriers cannot accommodate.

The second differentiator is the DOT Family Seating Dashboard ✅ commitment. Per the US Department of Transportation's April 2024 dashboard, United has committed to fee-free adjacent seating for children ≤14 on fee-eligible fares. Per the same dashboard, Delta Air Lines has not made this commitment, meaning Delta parents on many fares must pay seat-selection fees to guarantee sitting next to their child. American Airlines and Alaska Airlines share the ✅ status with United.

Where United lags is unaccompanied minor cost. Per Alaska Airlines' published policy, the UM fee is USD 50 each way — one-third of United's USD 150. For families sending children alone, Alaska's structure is materially cheaper. United's Group 1.5 family boarding is earlier than American's Group 4, a practical advantage for overhead bin access on packed transoceanic flights.

For parents flying international long-haul with an infant, United's pre-reservable bassinet with the industry's highest weight cap is the strongest argument in the carrier's favor. For domestic travel or UM logistics, the value proposition is solid but not exceptional.

## Family Pros & Cons
**Pros:**
- Industry-highest 15.8 kg / 35 lb Economy bassinet wall-mount cap on 777/787/767/757 international fleet
- DOT Family Seating Dashboard ✅ committed: fee-free adjacent seating for children ≤14 on fee-eligible fares
- Group 1.5 family boarding — earlier than any other US big-three carrier
- Pre-reservable bassinet seats by phone, with complimentary bulkhead seat for accompanying parent
- Free diaper bag exempt from carry-on counts on all routes
- Lap-infant international allowance includes one free checked bag up to 10 kg

**Cons:**
- International lap-infant additions require a phone call — online self-service not available
- USD 150 UM fee is among the highest of all US carriers — three times Alaska Airlines' USD 50
- United Express CRJ-200/E145/E175 regional jets return strollers at the baggage carousel, not the jet bridge
- Ages 5–7 UM restricted to non-stop flights only — no connections permitted
- No child fare discount for passengers 2 and older — full adult fare applies on all fare classes

## Parent Tips
- **Pre-reserve bassinet seats early**: Per United Airlines' published policy, bassinet seats on the 777/787/767 international fleet are limited to one to four per cabin and must be requested by phone. Call as early as possible after booking — popular routes like Newark–London or Chicago–Tokyo fill bassinet rows quickly, especially in Economy. Mention you have an infant under the 15.8 kg weight cap when calling.
- **Plan for United Express stroller returns**: Per United Airlines' published policy, mainline 777/787/737 MAX 9 flights return gate-checked strollers at the jet bridge. However, United Express regional jets — SkyWest CRJ-200, Republic E175, CommutAir E145 — typically return strollers at the baggage carousel. If your itinerary includes a regional-jet connection, use a compact or umbrella stroller that handles carousel handling better.
- **Use DOT seating rights for adjacent seats**: Per the US DOT Family Seating Dashboard, United has committed to fee-free adjacent seating for children ≤14. If you're booked on a fee-eligible fare and the system hasn't placed your child next to you, contact United before check-in — the carrier's published commitment requires resolution without an extra seat-selection fee on applicable fares.
- **Confirm Star Alliance Pacific JV connections**: United's Star Alliance Pacific joint venture with All Nippon Airways covers transpacific codeshare itineraries. Per United Airlines' published policy, family seating commitments apply only on United-operated metal — ANA-operated flight legs follow ANA's policy. Verify operating carrier on each segment before booking, and contact United for non-united-operated leg seat assignments.

## FAQ
### Are infants charged a fare on United Airlines?

Per United Airlines' published policy, infants under 24 months at time of travel may fly as lap infants without a base fare on US domestic routes — the ticket shows as USD 0.00 with no additional taxes. On international routes, the published fee is 10% of the adult base fare plus applicable government taxes and fees. For example, a USD 1,000 adult base fare would result in a lap-infant fare of USD 100 plus taxes. The key eligibility requirement is that the infant must be under 24 months on every segment of the trip — if a child turns 2 mid-trip, the remaining legs require a purchased seat at the full adult fare. Always verify the current fee structure at united.com before booking.

### Does my infant need their own seat on United Airlines?

Per United Airlines' published policy, infants under 24 months are not required to have their own seat — they may travel as lap infants held by a parent or guardian age 18 or older. However, the FAA strongly recommends that every child under 2 travel secured in an FAA-approved child restraint system (CRS) in their own purchased seat, as lap-held infants are at significantly greater risk of injury during turbulence or emergency stops. Per United Airlines' published policy, if you purchase a seat for your infant, the airline charges the full adult fare at the applicable fare class — there is no infant seat discount. The car seat must display the FAA-approved sticker to be used in-cabin. Gate-checking the car seat is free if you opt for the lap-infant ticket. Always confirm the seat width matches your car seat's base dimensions before boarding.

### Can I reserve a bassinet on United Airlines?

Per United Airlines' published policy, bassinets are available on the 757-200/-300, 767-300ER/400, 777-200/300ER, and 787-8/9/10 international fleet and can be pre-reserved by calling United Reservations before departure. The Polaris business-class fixed bassinet accommodates infants up to 11.3 kg / 25 lb, while the Economy wall-mount bassinet accepts infants up to 15.8 kg / 35 lb — the highest weight cap in the global airline industry, exceeding Singapore Airlines (14 kg), Emirates (11 kg), and Lufthansa. Each cabin has one to four bassinet positions. Families who reserve a bulkhead seat for the accompanying parent typically receive complimentary access to the adjacent seat for one companion as well. Availability is limited and fills quickly on popular transatlantic and transpacific routes — call as early as possible after booking.

### What's the child baggage allowance on United Airlines?

Per United Airlines' published policy, children 2 and older who have purchased a seat receive the full adult baggage allowance for their fare class — the same number of free carry-ons and checked bags as an adult on the same ticket. Lap infants (under 2, no seat purchased) do not receive an independent baggage allowance on domestic routes but may bring a free diaper bag that does not count against the parent's allowance. On international routes, per United Airlines' published policy, lap infants receive one free checked bag up to 10 kg / 22 lbs in addition to the free stroller and car seat check. Basic Economy domestic fares restrict carry-on bags for all passengers including children — verify fare-class rules before booking. Always check the most current United baggage fee schedule at united.com, as fees may vary by route and booking date.

### What are United Airlines' unaccompanied minor rules?

Per United Airlines' published policy, unaccompanied minor (UM) service is mandatory for children ages 5 through 14 traveling without an adult age 18 or older on the same itinerary. The fee is USD 150 each way per child — the same rate as American Airlines and Delta, and three times the USD 50 fee charged by Alaska Airlines. Children ages 5–7 are restricted to non-stop flights only; ages 8–14 may connect at United-operated airports on United-operated metal only — no interline or codeshare-partner connections. Children 15 and older may travel as adults. Booking must be completed by phone through United Reservations; online enrollment is not available. Both the drop-off adult and the authorized pick-up adult must present valid government-issued photo ID. Arrive at least 90 minutes before departure to complete UM documentation at the United ticket counter. Always verify the current UM policy at united.com before booking.

### What is United Airlines' bassinet weight limit?

Per United Airlines' published policy, the Economy wall-mount bassinet on United's international wide-body fleet accepts infants up to 15.8 kg / 35 lb — the highest bassinet weight cap in the global airline industry as of 2026. This compares favorably to the benchmarks: per Singapore Airlines' published policy, Singapore's bassinet cap is 14 kg / 30.8 lb; per Emirates' published policy, Emirates' cap is 11 kg / 24.2 lb. The Polaris business-class fixed bassinet on United's fleet carries a lower cap of 11.3 kg / 25 lb. The bassinet is available on the 757-200/-300, 767-300ER/400, 777-200/300ER, and 787-8/9/10 aircraft and is positioned at the bulkhead row. Parents of infants who exceed the weight caps of competing carriers — but still fall under 15.8 kg — may find United's Economy cabin uniquely accommodating for bassinet travel on long-haul routes. Always pre-reserve by phone as soon as possible after booking.

### Is United Airlines on the DOT family seating dashboard?

Per the US Department of Transportation's Family Seating Dashboard (April 2024), United Airlines has committed to fee-free adjacent seating for children age 14 and under when traveling on fee-eligible fares. This means United's booking system is required to seat a child next to an accompanying adult without charging an additional seat-selection fee on applicable fares. This places United on the ✅ committed-carrier list alongside American Airlines and Alaska Airlines. Per the same DOT dashboard, Delta Air Lines has not made this commitment, meaning Delta families may incur seat-selection fees to guarantee adjacency on certain fares. Note that Basic Economy fares with structural seating restrictions may be exempt from this commitment — verify the specific fare rules at the time of booking and always confirm adjacency before the flight departs. More details are available directly from the US DOT.

### Can I add a lap infant to my United booking online?

Per United Airlines' published policy, adding a lap infant online via 'My Trips' on united.com or the United mobile app is supported for most US domestic bookings. After completing your adult booking, navigate to 'My Trips,' select the itinerary, and use the 'Add Lap Infant' option. You will be asked to enter the infant's full legal name and date of birth, which must match the birth certificate. International itineraries and any booking where the operating carrier is a codeshare partner require a phone call to United Reservations — the online tool does not support these booking types. Parents booking complex international itineraries involving multiple carriers should call as early as possible, as agent wait times can be longer during peak travel periods. Always verify the infant is correctly listed on the updated booking confirmation before the travel date.

### Does United Airlines allow strollers on the plane?

Per United Airlines' published policy, strollers are accepted for free gate check or counter check on all United flights. The gate-check weight limit is 20 lbs / 9 kg — strollers under this limit can be wheeled to the jet bridge and handed to the gate agent just before boarding. Heavier jogging strollers, double strollers, or strollers over 20 lbs must be checked at the ticket counter. On mainline United flights (777, 787, 737 MAX 9), strollers are returned at the jet bridge upon arrival — a convenient experience for families. On United Express regional jet flights operated by SkyWest, Republic, and CommutAir (CRJ-200, E145, E175), strollers are typically returned at the baggage carousel, not the jet bridge. Parents on connecting itineraries that include a regional-jet segment should plan for the carousel retrieval when choosing a stroller for travel.

### Does United Airlines offer family boarding?

Per United Airlines' published policy, family boarding is available for passengers traveling with children under 2 years old, or who are carrying strollers or car seats to the gate. United designates this as Group 1.5 — it occurs after Premier 1K and Global Services elite members have boarded, but before all standard Groups 2 through 5. This is meaningfully earlier in the boarding sequence than American Airlines' family boarding in Group 4. No additional fee applies for family boarding, and no special registration is required — the gate agent will announce the Group 1.5 family boarding call. Boarding early gives families with young children extra time to install car seats, stow carry-on bags in overhead bins, and get young children settled before the general boarding rush. Always listen for the gate announcement to avoid missing the dedicated family call.

### Does United Airlines have a child fare discount?

Per United Airlines' published policy, there is no standard child fare discount for passengers 2 years of age and older. Every child 2+ pays the full adult base fare at the applicable fare class — Economy, Economy Plus, or Polaris — on all domestic and international routes. This is consistent with the practice of all five US-legacy carriers: Delta, American, United, Alaska, and Hawaiian all publish adult-equivalent fares for children 2 and older. By contrast, per Lufthansa's published policy, Lufthansa offers a percentage discount on certain international fares for children under 12, and per All Nippon Airways' published policy, ANA offers child discounts on domestic Japanese routes. US families should plan family budgets for United travel with the expectation that every seat-occupying child carries the same fare as the adults in the booking.

### What documents does my infant need to fly on United Airlines?

Per United Airlines' published policy, infants traveling as lap infants must be able to demonstrate their age at check-in if requested. Acceptable documents include a birth certificate (original or certified copy), a passport, or a government-issued photo ID that clearly shows the infant's date of birth. For international travel, a passport is required for the infant in virtually all cases — a birth certificate is generally not accepted at international border control. Immunization records showing date of birth may be accepted at the gate as an additional verification document. Parents should ensure the name on all documents matches the name entered into the booking exactly, as mismatches can cause delays at the airport. For infants under 7 days old, travel is not permitted per United Airlines' published policy. Always verify the specific document requirements for your destination country at united.com or through United Reservations before departure.
