Car Seat on Alaska Airlines: The Complete 2026 Guide
Alaska is the only US carrier with a numbered-row car seat exclusion on the Embraer E175 — rows 1–4 are banned. Window preferred, CARES is the only approved ACSD, and one car seat per child flies free.
Yes — per Alaska Airlines' published policy, FAA-approved car seats are free as checked baggage and may be installed in a purchased seat in the cabin, with window preferred, never in the aisle, exit row, or rows fore/aft of exits, and not in rows 1–4 on Embraer E175 aircraft.

The Exact Alaska Policy
Word-for-word from the official source — no paraphrasing.
“We will transport your child's car seat and stroller free of charge as checked baggage. You can check these items with your other baggage, or wait until you reach the gate area.”
How It Works on Alaska
Every phase of your trip — written for this airline's specific process and terminology.
Before You Leave
Prep — verify labels and book the right seat
Verify the red FAA certification label
1 week aheadPer 14 CFR 121.311(b)(2)(ii), the seat must display 'This restraint is certified for use in motor vehicles and aircraft.' Alaska's published policy requires both the FMVSS and the aircraft-certification label. Seats made before 26-Feb-1985 are not eligible.
Check seat width against the aircraft
At bookingFAA recommends a CRS width of 16 inches or less. On Alaska 737-800/900ER/MAX 9 the standard economy seat pitch accommodates most convertible seats; on Horizon E175 the seat is narrower — avoid wide convertibles.
Book a window seat (or confirm aisle workaround)
At bookingPer Alaska's policy: 'window preferred; middle if window vacant or seat doesn't block aisle; not in aisle, exit row, or rows fore/aft.' If your child has a purchased seat in First or Premium Class, the seating preference still applies.
At Security
TSA checkpoint — X-ray the car seat
X-ray the car seat
At SEA/PDX/ANC checkpointPer TSA: 'Strollers, umbrella-strollers, baby carriers, car and booster seats and backpacks must be screened by X-ray.' Larger convertibles get a physical inspection.
Remove the child from the car seat
At checkpointTSA: 'Remove infants and children from strollers and car seats and carry them in arms through the walk-through metal detector.'
At Alaska Gate
Gate area — confirm aircraft type and pre-board
Request family pre-boarding
At gateAlaska boards families with children under 2 before First Class and MVP — earliest among US legacy peers. Use this window to install the car seat without aisle congestion.
“We're pre-boarding with a car seat for our paid infant seat.”
Confirm aircraft type if connecting to Horizon
At gateEmbraer E175 routes (typical SEA-PSC, PDX-RDM, etc.) ban car seats in rows 1–4. If your seat assignment falls there, request a row change at the gate before boarding.
Onboard
In the cabin — install correctly
Install rear-facing per FAA + manufacturer instructions
BoardingForward-facing aircraft seat, generally at the window, never blocking egress. Booster seats may not be used during taxi, takeoff, landing, or surface movements per Alaska's published rule.
Use seat power if needed (Alaska best-in-class)
In flightPer Alaska's newsroom: 110-volt and USB power at every seat on approximately 75% of the fleet. Practical for charging a connected car-seat base sensor or a tablet during long sectors.
At Destination
Deplaning — retrieve and inspect
Retrieve the car seat at jet bridge or baggage claim
DeplaningIf gate-checked on mainline 737/A321: jet-bridge return. On Horizon E175: baggage claim. If used in-cabin with a purchased seat, no retrieval needed.
Inspect for damage before leaving the airport
At carouselIf damaged, file at the Alaska Baggage Service Office in the destination airport. No central 800 baggage number — find your airport's office at alaskaair.com/content/travel-info/baggage/baggage-claim/airport-baggage-offices.
Pick Your Trip Type
E175 row rules, seat-power for monitors, and widebody long-haul installs — what to plan.
Verify the aircraft is E175 — if so, avoid rows 1–4 for car-seat installation. Many parents gate-check on this short sector and use a CARES harness on the lap-fare alternative.
- Per Alaska's policy: 'not in rows 1–4 on Embraer E175'
- Horizon E175 returns gate-checked seats to baggage carousel, not jet bridge
- FAA recommends CRS ≤16 in width for narrow Embraer seats
Purchase a paid infant seat and install the car seat at the window. Alaska's 737 MAX 9 has 110V + USB at every seat — useful for connected car-seat-base monitors and CARES harness alternates.
- Likely aircraft: 737 MAX 9 with 110V + USB at every seat
- Window preferred per Alaska policy; never aisle or exit row
- CARES harness accepted (22–44 lbs, ≤40 in) — Alaska names AmSafe CARES as the only approved ACSD
Buy a seat for the infant; install an FAA-approved convertible at the window. Alaska Air Group operates the 787-9 on long-haul international post-Hawaiian acquisition. No bassinet program.
- No mainline bassinet on Alaska — no bassinet alternative to car-seat install on long-haul
- International liability: Montreal Convention 1,519 SDR cap (eff. 28-Dec-2024)
- Window install per Alaska policy applies on widebody seat maps as well
Federal Rules vs Alaska's Rules
Where the airline aligns with TSA/FAA — and where it goes further.
What Alaska Won't Put in Writing
Don't book rows 1–4 on the Horizon E175
Alaska is the only US carrier with a numbered-row car-seat exclusion. Per published policy, rows 1–4 on the Embraer E175 cannot accept a CRS. The E175 operates many SEA-PSC, PDX-RDM, and intra-Pacific-Northwest short hops — check the operating carrier on your Mileage Plan reservation and pick row 5 or later.
Verify both labels before SEA TSA
Per 14 CFR 121.311 and Alaska's policy, the CRS must show both the FMVSS sticker and the red 'certified for use in motor vehicles and aircraft' label. Seats manufactured before 26-Feb-1985 are categorically not eligible — this is the most common Alaska gate-agent rejection reason.
Use the 737 MAX 9 power for car-seat-base monitors
Per Alaska's newsroom, 110V + USB is at every seat on ~75% of the fleet — best onboard power of any US carrier. Connected car-seat-base monitors can stay powered on long sectors. Not guaranteed on older 737-800 retrofits.
Use 800-503-0101 to confirm aircraft type
Accessible Services (24/7) is the right line for car-seat questions — they can confirm whether your booked routing is mainline 737/A321 or Horizon E175 before you reach the gate. The reservations line (800-252-7522) will redirect you.
What Parents Experienced on Alaska
Recent, route-specific, verified.
During the January 2024 Alaska Flight 1282 Boeing 737 MAX door-plug blowout out of Portland, one mother holding her baby on her lap feared her son had been blown out of the fuselage; he was unharmed. Three infants were aboard. The NTSB subsequently renewed recommendations that children two and under have their own seats and restraints instead of riding as lap infants — making this incident the most cited federal-safety-position story in US family aviation.
A frequent-flying family (a child with 100+ flights by 18 months) reported Alaska checks car seats and strollers free at the gate or as hold luggage and lets parents bring both to the gate — contrasting it favorably with American, which gate-checks only one. They noted Alaska also accepts the CARES harness without friction.
What To Do at the Gate If They Say No
Alaska itself rarely refuses an FAA-approved car seat at the gate. Friction lives in two seams: a CRS without the 'certified for use in motor vehicles and aircraft' label, and a Horizon E175 gate agent moving a family out of rows 1–4.
- 1
Cite 14 CFR 121.311 and the labeling requirement
Specifically reference 14 CFR 121.311(b)(2)(ii). Keep a screenshot of the red label on your phone. Most gate agents back down when you name the regulation.
“This car seat meets FAA 14 CFR 121.311(b)(2)(ii) — it has both the FMVSS label and the red 'certified for use in motor vehicles and aircraft' label.”
- 2
Request the Alaska gate supervisor
On E175 row-exclusion challenges, request reseating to row 5+ rather than rejection of the CRS. The E175 row 1–4 ban is aircraft-configuration-based, not a policy discretion call.
- 3
File a DOT Aviation Consumer Protection complaint
File within 30 days if the FAA-compliant CRS is refused. Document officer name, time, location, and badge number.

Alaska + Car Seat: FAQ
Does Alaska Airlines charge for car seat check?
No. Per Alaska's published policy: 'We will transport your child's car seat and stroller free of charge as checked baggage. You can check these items with your other baggage, or wait until you reach the gate area.' One car seat per child is free of the standard baggage allowance, regardless of fare class or Mileage Plan status.
Can I use my car seat on the plane on Alaska?
Yes, with a purchased seat. Per FAA 14 CFR 121.311 and Alaska's policy, the CRS must be FAA-approved (red 'certified for use in motor vehicles and aircraft' label, post-26-Feb-1985), installed at a window, never in an exit row or rows fore/aft of exits, and never in rows 1–4 on Embraer E175 regional aircraft.
What car seats are FAA-approved on Alaska?
Per FAA 14 CFR 121.311(b)(2)(ii), any forward-facing CRS made on or after 26-Feb-1985 with the red 'This restraint is certified for use in motor vehicles and aircraft' label. Alaska's published policy names AmSafe CARES as the only approved ACSD (harness) alternative for children 22–44 lbs and ≤40 inches tall. Booster seats may not be used during taxi, takeoff, landing, or surface movements.
Can I bring a CARES harness on Alaska Airlines?
Yes. Per Alaska's published supplemental policy: 'AmSafe CARES Restraint is the only approved ACSD' for 22–44 lb / ≤40 in. The CARES is FAA-approved for taxi, takeoff, landing, and turbulence. Alaska does not accept vest-type or belly-belt restraints.
Why can't I use a car seat in rows 1–4 on Alaska?
This restriction applies only to the Embraer E175 regional aircraft (operated by Horizon Air). Per Alaska's published policy: 'not in aisle, exit row, or rows fore/aft; not in rows 1–4 on Embraer E175.' The first four rows of the E175 have configuration constraints around emergency egress and bulkhead geometry. This is the only US carrier with a numbered-row CRS exclusion.
Can I install a rear-facing car seat in First or Premium Class on Alaska?
Yes, in principle — Alaska's policy does not ban CRS from First or Premium Class. The window-preferred rule still applies, and the seat must not block aisle egress. Inflatable-seatbelt rows (varies by aircraft) bar CRS installation industry-wide; confirm at the gate. Lap infants are barred from inflatable-seatbelt rows per Alaska.
Where do I get my car seat back after an Alaska flight?
If gate-checked on mainline 737/A321/A321neo: jet-bridge return. On Horizon Air-operated E175 flights: baggage carousel. If used in-cabin with a purchased seat, no retrieval needed.
Is Alaska liable if they damage my car seat?
Alaska publishes no baby-gear-specific damage disclaimer. Liability defaults to the Contract of Carriage and the 14 CFR 254.4 domestic minimum of $4,700 (since 22-Jan-2025). However, per DOT guidance, carriers may exclude fragile/bulky items, and car seats are routinely excluded on every major US carrier. File at the Alaska Baggage Service Office in your destination airport; there is no central 800 baggage number.
