# Flying Allegiant Air with Kids: Infant Fees, Stroller Policy & Family Boarding

## Family Boarding
- **Available**: Yes
- **Boarding Zone**: Pre-board (families with children under 2)
- **Age Eligibility**: Children under 2 years old

Per Allegiant Air's published policy, families traveling with children under 2 years old may pre-board before the general boarding zones. Allegiant is not on the US DOT Family Seating Dashboard's commitment list, so seat adjacency is not guaranteed without paid seat selection.

## Stroller & Car Seat
Per Allegiant Air's published policy, one stroller and one car seat per fare-paying passenger may be checked free at the ticket counter or at the boarding gate. The uniform A319/A320/A321 fleet supports jet-bridge stroller return at most major airports served.

- **Standard Stroller** — Fee: Free, Check at: Gate or ticket counter, Size: No published size limit. Umbrella, full-size, and double strollers all accepted; use through the terminal until the boarding door.
- **Car Seat** — Fee: Free, Check at: Gate or ticket counter, Size: FAA-approved sticker required for in-cabin use. One free per fare-paying passenger; FAA sticker required only if intending to install in-cabin on a paid seat.
- **Booster Seat** — Fee: Free, Check at: Gate or ticket counter, Size: Treated as a child safety device. Checked under the same free child-safety-device allowance as a car seat; backless boosters are NOT FAA-approved for in-cabin use during flight.
- **Pack-n-Play / Travel Crib** — Fee: Standard checked-bag fee applies (USD 25–75), Check at: Ticket counter only, Size: Standard checked-bag dimensions apply. Not included in the free child-safety-device allowance — charged as a regular checked bag at prevailing counter fees.

## Baggage by Age
- **Lap Infant (Under 24 months)** — Carry-on: None — shares parent's purchased allowance; Checked: None included; Personal: 1 free diaper bag per child (extra to parent's allowance). No paid seat means no individual baggage entitlement; diaper bag exemption is the only extra.
- **Infant with Paid Seat (Under 24 months)** — Carry-on: Same as adult A-La-Carte fare (carry-on fee USD 25–75 if purchased); Checked: Same as adult fare — standard checked-bag fees apply; Personal: 1 personal item (fee USD 0–35) + 1 free diaper bag. Purchasing a seat grants the infant the same A-La-Carte allowance as an adult; fees still apply per the fare type.
- **Child 2+ (Full Fare Passenger)** — Carry-on: Same as adult A-La-Carte fare (carry-on fee USD 25–75 if purchased); Checked: Standard checked-bag fees apply; Personal: 1 personal item (fee USD 0–35). All passengers aged 2 and older pay the full adult fare; no child discount on baggage or base fare.

## Bassinet & Onboard
- **Bassinet Available**: No




Per Allegiant Air's published policy, bassinets are not available on any aircraft in the fleet. The all-Airbus A319/A320/A321 narrow-body configuration does not include bulkhead bassinet attachment points. There is no in-flight entertainment, no Wi-Fi, and no dedicated kids' meal program — bring everything your child needs on board.

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

According to Allegiant Air's published information, children aged 2 and older are charged the full prevailing adult fare on all routes. This is consistent with the US ultra-low-cost carrier standard — Frontier and Spirit similarly offer no published child fare discount. European and Middle Eastern legacy carriers (including Lufthansa at ~20% and Air France at up to 33%) offer meaningful child discounts on qualifying fare classes, which represent a structural advantage for long-haul families over Allegiant's model. Always verify the booking total before purchase, as promotional fare banners can be misleading about true per-passenger cost.

## Unaccompanied Minor
- **Available**: No


According to Allegiant Air's published information, the carrier does not transport unaccompanied minors under the age of 15. Children aged 15 through 17 may travel without an adult companion but are processed as standard adult passengers — no UM escort service, no gate-pass for drop-off parents, and no special supervision program.

## Industry Comparison
### How Allegiant Air stacks up against the US ULCC family travel benchmark

Allegiant Air scores 5.2 overall in the US ultra-low-cost carrier cluster — tied with Avelo Airlines and below Spirit Airlines (5.6, cluster leader), Sun Country Airlines (5.5), and Frontier Airlines (5.3). Two structural gaps drive the score: Allegiant is not on the US DOT Family Seating Dashboard's commitment list for free seat adjacency, and it does not transport unaccompanied minors under age 15 — shared only with Frontier and Avelo. Per Spirit Airlines' published policy, the carrier accepts unaccompanied minors aged 5–14 at USD 150 each way; per Sun Country Airlines' published policy, the fee is USD 75 each way — both offer a service Allegiant cannot match.

On the baggage dimension, Allegiant's A-La-Carte fee structure charges for both carry-on (USD 25–75) and personal item (USD 0–35) on non-elite fares — more aggressive than Frontier's model, which typically includes one free personal item. The pending Allegiant and Sun Country merger (expected to close approximately May 2026) will combine two leisure-focused narrow-body networks into the largest US leisure carrier by route count, though family policies for each operating certificate are expected to remain distinct through the transition.

Where Allegiant earns credit: free lap-infant on domestic and international Mexico, Caribbean, and Bahamas routes — broader than the domestic-only scope some parents assume. Stroller and car seat gate-check is free per fare-paying passenger with jet-bridge return, and the diaper bag exemption offsets the double carry-on and personal item fee. The April 2025 birth-certificate proof requirement is a recent change worth noting. For short-haul leisure trips where families pack light and travel with adults only, Allegiant delivers functional core policies at bare-fare prices. Families needing solo child travel or guaranteed seat adjacency should compare Southwest Airlines and Spirit Airlines as better-suited alternatives.

## Family Pros & Cons
**Pros:**
- Lap infants under 24 months fly free on domestic and Mexico/Caribbean/Bahamas leisure routes — no infant surcharges
- One stroller and one car seat per fare-paying passenger are gate-checked free with jet-bridge return on the uniform A319/A320/A321 fleet
- One diaper bag per child is free and does not count toward the carry-on or personal item allowance
- Pre-boarding is available for families traveling with children under 2 years old at no extra charge
- Pack-n-play and travel cribs accepted as checked baggage without oversized-item surcharges

**Cons:**
- Per Allegiant Air's published policy, allegiant does not transport unaccompanied minors under age 15 — the strictest UM policy in the US ULCC cluster alongside Frontier and Avelo
- Not on the US DOT Family Seating Dashboard commitment list — seat adjacency for families requires paid selection (USD 5–30 per seat)
- A-La-Carte fees apply to both carry-on (USD 25–75) AND personal item (USD 0–35) on non-elite fares — the most aggressive dual-fee structure in the cluster
- No bassinets, no in-flight entertainment, no Wi-Fi, and no dedicated kids' meals on any aircraft
- Adding a lap infant requires a phone call; online addition is not supported and a USD 15–35 agent fee may apply

## Parent Tips
- **Tag gear at the counter**: Per Allegiant Air's published boarding process, strollers and car seats can be tagged at the ticket counter or at the gate. Tagging at the ticket counter at low-volume Allegiant focus airports (Sanford, Punta Gorda, Mesa) is faster than gate-tagging on small leisure-route departures with no priority queue.
- **Budget the agent fee for adding infant**: Adding a lap infant to an Allegiant booking requires a phone call, and per Allegiant Air's published policy an agent assist may apply on top of the standard fare-difference. Book the infant simultaneously with the adult ticket to avoid this post-booking phone fee on the all-Airbus narrow-body fleet.
- **No UM option under 15 — plan early**: According to Allegiant Air's published information, the carrier does not accept unaccompanied minors under age 15 on any route. Families needing solo travel for younger children must select Spirit (UM 5-14 at USD 150 each way) or Sun Country (UM 5-14 at USD 75 each way on non-stop routes).
- **Preload everything before boarding**: Per Allegiant Air's published operational setup, there is no seat-back IFE, no streaming Wi-Fi, and no in-seat power on any Allegiant aircraft. For flights longer than 90 minutes, download movies, shows, and kids' apps to tablets before leaving home. Bring a fully charged portable battery pack — power outlets are not available at any seat.
- **Buy seats to sit together**: Velivolo's family travel data shows seat adjacency disputes are the top complaint among families flying airlines without a DOT family-seating commitment. Allegiant is in this group. To avoid being split, purchase advance seat assignments at booking — the USD 5-50 per-seat fee is cheaper than the gate-agent reseat lottery.

## FAQ
### Are infants charged a fare on Allegiant Air?

Per Allegiant Air's published policy, infants under 24 months at time of travel may fly as lap infants without a base fare on US domestic routes and on the carrier's international leisure routes to Mexico, the Caribbean, and the Bahamas. No infant taxes or fuel surcharges are layered on top of the USD 0 fare on these routes. A birth-certificate proof-of-age requirement was introduced in April 2025. Adding the infant requires a phone call to Allegiant Reservations — online addition is not supported — and an agent assistance fee of USD 15–35 may apply. If the infant turns 2 during the trip, the return leg requires a full paid seat at the prevailing adult fare. Always verify the current policy directly at allegiantair.com before booking.

### Does my infant need their own seat on Allegiant Air?

Per Allegiant Air's published policy, infants under 24 months may travel as lap infants without purchasing a dedicated seat. However, the FAA strongly recommends that every child under 2 fly secured in their own approved child-restraint system (CRS) rather than on a parent's lap, as the lap position provides the least protection in turbulence or impact events. If you choose to purchase a seat for your infant to use an FAA-approved car seat, the seat is charged at the full prevailing adult fare — Per Allegiant Air's published policy, allegiant does not offer an infant-seat discount. The decision depends on flight duration, the number of children traveling, and whether you plan to gate-check or install the car seat in-cabin. Always verify current policy at allegiantair.com before traveling.

### Can I reserve a bassinet on Allegiant Air?

Per Allegiant Air's published policy, bassinets are not available on any aircraft in the Allegiant fleet. The carrier operates exclusively Airbus A319, A320, and A321 narrow-body aircraft on US domestic and short-haul international leisure routes. These aircraft do not have bulkhead bassinet attachment hardware. Babies must be held on a parent's lap for the duration of the flight, or placed in an FAA-approved car seat if a paid seat has been purchased. Parents who require bassinet access for infants on longer routes should consider full-service or wide-body carriers — per Singapore Airlines' published policy, for example, bassinets are available on long-haul wide-body aircraft. Verify Allegiant's current fleet configuration at allegiantair.com before booking.

### What is the child baggage allowance on Allegiant Air?

Per Allegiant Air's published fee schedule, children aged 2 and older receive the same A-La-Carte baggage allowance as adult passengers — meaning carry-on bags (USD 25–75) and personal items (USD 0–35) are subject to the same fees. There is no child baggage discount. Lap infants receive no individual baggage entitlement. The one family-specific exemption is the diaper bag: per Allegiant Air's published policy, one diaper bag per traveling child is permitted free of charge and does not count toward the carry-on or personal item allowance. This dual-fee structure — both carry-on and personal item potentially charged — is the most aggressive baggage model among major US ultra-low-cost carriers. Budget accordingly before booking, and always verify current fee schedules at allegiantair.com.

### What are Allegiant Air's unaccompanied minor rules?

According to Allegiant Air's published information, the carrier does not transport unaccompanied minors under the age of 15. No UM escort service, age-tiered program, or gate-pass system exists for passengers under 15 — this is a hard policy that applies on all Allegiant domestic and international routes. Children aged 15 through 17 may travel without an adult companion but are processed as standard adult passengers with no airline supervision. Parents who need a child under 15 to travel alone should use Spirit Airlines (UM accepted ages 5–14, USD 150 each way, non-stop routes) or Sun Country Airlines (UM accepted ages 5–14, USD 75 each way, non-stop routes). Always verify the current policy directly at allegiantair.com before booking any solo-child itinerary.

### Does Allegiant charge for carry-on bags and personal items?

Per Allegiant Air's published fee schedule, both carry-on bags and personal items may be charged on non-elite fares under the carrier's A-La-Carte pricing model. Carry-on fees range from approximately USD 25 to USD 75 depending on route, timing of purchase, and fare type. Personal item fees range from approximately USD 0 to USD 35. This dual-fee structure is uniquely aggressive among US ultra-low-cost carriers — Frontier Airlines typically includes one free personal item, and Spirit Airlines similarly includes a free personal item while charging for carry-ons. The one family exception is the diaper bag: per Allegiant Air's published policy, one diaper bag per traveling child is free and does not count against any allowance. Fees are lowest when purchased at the time of initial booking; purchasing at the gate is the most expensive option. Always verify current fees at allegiantair.com.

### Does Allegiant Air have family boarding?

Per Allegiant Air's published policy, families traveling with children under 2 years old may pre-board before the general boarding zones begin. This pre-boarding is automatic — no special request or fee is required. However, Allegiant is not on the US DOT Family Seating Dashboard's commitment list for free guaranteed seat adjacency, which means families who have not purchased assigned seats may be placed in separate rows by the system at check-in. Paid seat selection (approximately USD 5–30 per seat depending on route and position) is the only reliable way to guarantee that family members sit together. Gate agents may assist with reseating on request, but this is not guaranteed on full flights. Verify current boarding procedures at allegiantair.com before travel.

### Are strollers free to gate-check on Allegiant?

Per Allegiant Air's published policy, one stroller per fare-paying passenger may be gate-checked or counter-checked free of charge. This applies to umbrella strollers, full-size strollers, and double strollers — no published size or weight limit restricts the free stroller allowance. To gate-check, families walk through security with the stroller in use, push it to the boarding gate, and hand it to the gate agent at the jet bridge door before boarding. The stroller is loaded into the cargo hold and returned at the jet bridge upon arrival at most Allegiant airports. Allegiant's uniform A319/A320/A321 fleet supports jet-bridge stroller return at most major stations. Tagging the stroller at the ticket counter rather than the gate is recommended to avoid last-minute gate congestion. Verify current policy at allegiantair.com.

### Is Allegiant Air merging with Sun Country Airlines?

According to publicly available information as of May 2026, Allegiant Air and Sun Country Airlines have announced a merger deal expected to close approximately May 2026. The combined entity would unify two leisure-focused narrow-body carrier networks under one parent company, creating what would be the largest US leisure-focused carrier by route count. Per Allegiant Air's published policy, children do not fly free except as lap infants under 24 months. Passengers aged 2 and older pay the full prevailing adult fare — there is no published child fare discount on any Allegiant route or fare class. Occasional promotional 'Kids Fly Free' offers have appeared historically on select routes or bundled Allegiant Vacations packages (flight plus hotel), but these are time-limited marketing promotions, not a standing policy. The promotional fare may technically be listed as zero, but the overall bundle cost typically reflects the discount elsewhere. For families seeking a structural child-discount, European carriers such as Lufthansa (~20% on Standard fares) or Air France (up to 33% on long-haul Standard) offer published discounts. Always verify the booking total before purchase and confirm any promotional offer terms at allegiantair.com.

### Does Allegiant offer a discount for children's tickets?

Per Allegiant Air's published policy, the airline does not offer a child fare discount for passengers age 2 and older — children travel at the full prevailing adult fare on Standard, Discount Den, and bundled fare types alike. This is consistent with US ULCC peers including Spirit, Frontier, Avelo, and Sun Country, none of which apply a child discount on standard fares. Lap infants under 24 months continue to fly free of base fare on US domestic and Caribbean/Mexico/Bahamas routes. The pending Allegiant + Sun Country merger (expected ~May 2026) is unlikely to introduce a child fare discount, given that neither carrier currently publishes one. For families seeking a child fare discount, European-legacy carriers (Lufthansa, Air France, KLM) and Asian-premium carriers (Singapore Airlines, ANA, JAL) publish ~20–33% discounts on Standard fares — Always verify the latest policy directly at allegiantair.com before booking.
