What airlines, hotels, and carriers currently require — and where your letter still protects you.
Flying out of Washington with your animal? The rules differ sharply between ESAs and psychiatric service dogs — here’s what airlines currently require.
Seattle–Tacoma International is the Pacific Northwest’s hub.
Since the U.S. Department of Transportation’s 2021 rule change, airlines may treat emotional support animals as pets: expect a pet fee, an under-seat carrier for small animals, and cargo restrictions for larger ones. Policies differ by airline, so check yours before booking out of Washington.
Task-trained PSDs keep their cabin access at no charge. Airlines may require the DOT Service Animal Transportation Form attesting to training and behavior — most ask for it 48 hours ahead. The dog must fit within your foot space and remain under control.
On the ground, the ADA governs — and it covers task-trained service animals, not ESAs, so hotels and carriers may apply pet policies. Where the letter keeps its force is lodging that counts as housing: leases, sublets, and many longer rentals at your destination beyond Washington.

Yes, but as a pet: expect a fee and an under-seat carrier requirement. The DOT removed the airline obligation to treat ESAs as service animals in 2021.
A task-trained psychiatric service dog flies in the cabin at no charge. Most carriers ask for the U.S. DOT Service Animal Transportation Form, usually 48 hours ahead.
It remains essential for housing at your destination — short-term rentals and leases — and some carriers and hosts voluntarily accommodate documented ESAs, but it doesn’t create a legal right to fly.
Treat it as pet travel — reserve early since cabin pet slots sell out, check your airline’s carrier rules, and expect a fee in each direction.
Yes, but narrowly: incomplete DOT paperwork, disruptive behavior, or space constraints are the recognized grounds.
