What airlines, hotels, and carriers currently require — and where your letter still protects you.
Flying out of Arizona with your animal? The rules differ sharply between ESAs and psychiatric service dogs — here’s what airlines currently require.
Phoenix Sky Harbor International handles the bulk of Arizona departures, with Tucson International as the southern alternative — at both, ESAs board as pets.
The DOT’s 2021 rule change ended mandatory ESA accommodation in the air. Practically, that means pet fees, an under-seat carrier for small animals, and cargo rules for big ones — with details varying by carrier, so confirm before flying out of Arizona.
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 Arizona.
No hidden fees · HIPAA secure · Pay only if approved.
Task-trained psychiatric service dogs still fly free in the cabin. Airlines may require the U.S. DOT Service Animal Transportation Form, typically submitted 48 hours before departure.
Hotels are public accommodations under the ADA, which covers service animals — not ESAs — so pet policies and fees can apply. Many Arizona hotels are pet-friendly; confirm before booking.
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.
Only in limited cases — missing DOT forms, a dog that’s out of control or too large for your foot space, or specific long-haul requirements.
Yes — destination-country animal import rules apply on top of airline policy, and several countries require advance permits or quarantine.
