Alaska Airlines is one of the more pet-friendly major U.S. carriers, allowing small dogs and cats in the cabin on most routes. This guide covers Alaska's current pet-in-cabin policy, what changed for emotional support animals after the 2021 DOT rule, and what options exist for travelers who need more than a standard in-cabin pet arrangement.
Alaska Airlines Pet Policy: In-Cabin Pets (2026)
Alaska Airlines allows passengers to bring small pets in the cabin on domestic flights. Here is what their policy covers:
- Eligible pets: domesticated cats, dogs, and rabbits
- Size limit: pet plus carrier must fit under the seat in front of you; combined weight is typically under 20 lbs
- Carrier requirement: a soft-sided, ventilated carrier that fits under the seat
- Fee: Alaska charges a one-way pet-in-cabin fee (check Alaska's current website for the exact amount, as fees are subject to change)
- Availability: space is limited per flight; book your pet space early during reservation
Pets must remain in their carrier under the seat for the entire flight. They cannot be placed in overhead bins.
Cargo Pet Policy
Alaska Airlines also allows larger dogs and cats to travel as checked baggage in the cargo hold on select routes and during certain seasons. Temperature restrictions apply - Alaska does not transport pets in cargo when extreme temperatures are expected at origin, destination, or connecting cities. Check Alaska's website for current seasonal restrictions before booking.
Important: ESA Policy Change After the 2021 DOT Rule
Since the 2021 DOT rule change, U.S. airlines are no longer required to accept emotional support animals in the cabin as a disability accommodation. This applies to Alaska Airlines. ESAs are now treated as regular pets under Alaska's pet-in-cabin policy - they must meet all standard requirements (size, carrier, fee) and are not given accommodation status.
What this means for ESA owners flying Alaska Airlines:
- Your ESA letter does not entitle your animal to fly in-cabin for free
- Your ESA must meet Alaska's standard pet size requirements to fly in-cabin
- Larger ESAs that exceed the in-cabin size limit cannot fly in-cabin on Alaska regardless of your ESA letter
Psychiatric Service Dogs on Alaska Airlines
Psychiatric service dogs (PSDs) are trained service animals under the DOT Air Carrier Access Act - a separate legal category from ESAs. Alaska Airlines does accommodate trained service dogs in the cabin at no charge, following DOT regulations. To fly with a PSD on Alaska Airlines:
- Complete Alaska's service animal form in advance of your flight (required by DOT)
- Your service dog must be trained to perform specific tasks related to your psychiatric disability
- Your service dog must behave appropriately in the aircraft cabin (harnessed and under control)
If you currently have an ESA and need air travel accommodation for a larger dog, transitioning to a PSD with verified task training is the path forward. See our complete PSD letter guide for details.
Alaska Airlines Service Animal Documentation
Alaska requires advance documentation for service animals, including PSDs. The DOT's service animal form asks for confirmation that the animal is trained, the handler has a disability, and the animal will behave appropriately in the aircraft environment. This form must be submitted to Alaska's accessibility desk in advance of travel.
Tips for Traveling With a Pet on Alaska Airlines
- Book early - pet cabin space is limited and fills quickly on popular routes
- Confirm your pet booking after purchasing your ticket; it is a separate step
- Use an airline-approved soft-sided carrier; hard carriers are not permitted in-cabin
- Acclimate your pet to the carrier before the flight to reduce travel stress
- Bring absorbent pads in the carrier in case your pet cannot hold their bladder on a long flight
Frequently Asked Questions About Alaska Airlines Pet Policy
Q: Can I bring my dog in-cabin on Alaska Airlines for free with an ESA letter?
No. Since the 2021 DOT rule change, ESA letters do not entitle your animal to fly in-cabin at no charge. Your dog must meet Alaska's standard pet-in-cabin requirements and fees. If you need your dog to fly as an accommodation, a trained psychiatric service dog qualifies under separate DOT regulations.
Q: Does Alaska Airlines allow large dogs in the cabin with a service dog designation?
Yes, trained service dogs - including PSDs - can fly in-cabin regardless of size, as long as they are under handler control and do not occupy a seat. The dog typically sits at the handler's feet or on the floor in front of the seat.
Q: Can my ESA fly in cargo on Alaska Airlines?
Alaska allows pets to fly as checked baggage in cargo on select routes, subject to size, weight, and temperature restrictions. This is separate from ESA status - it is Alaska's standard cargo pet policy.
Need a PSD Letter for Air Travel?
If you need your dog to travel with you as an accommodation and they exceed standard in-cabin pet size limits, a psychiatric service dog evaluation may be appropriate. Start your evaluation here to learn whether you qualify for a PSD letter.

Alaska Airlines Pet Travel Checklist
To avoid problems at the gate, prepare your Alaska Airlines pet trip carefully:
- Book the pet reservation at the time of flight booking - Alaska limits the number of pets per flight and spots fill quickly on popular routes
- Confirm your carrier meets the under-seat dimensions for your specific aircraft (dimensions vary by plane type - check Alaska's website or call to confirm)
- Have your pet's current health certificate ready if requested (some international routes require it)
- Bring water, an absorbent pad for the carrier, and your pet's favorite comfort item
- Arrive with extra time - checking in a pet at the counter adds a few minutes to the process
