The current rules for flying and staying with your animal — and where your Maryland letter still counts.
Flying out of Maryland with your animal? The rules differ sharply between ESAs and psychiatric service dogs — here’s what airlines currently require.
BWI Marshall is the state’s hub, with Reagan National and Dulles minutes away for many residents.
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 Maryland.
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 Maryland.
No hidden fees · HIPAA secure · Pay only if approved.
Only under your airline’s standard pet policy — usually a carrier under the seat and a pet fee. Since 2021, airlines aren’t required to treat ESAs as service animals.
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.
Not automatically. The ADA covers task-trained service animals, so a Maryland hotel may treat an ESA as a pet with its usual policy and fees — call ahead.
Book under your airline’s pet policy: reserve the pet spot early (cabins cap the number), confirm carrier dimensions, and budget for the pet fee each way.
Yes, but narrowly: incomplete DOT paperwork, disruptive behavior, or space constraints are the recognized grounds.
