What airlines, hotels, and carriers currently require — and where your letter still protects you.
Before you book a flight from Nevada, know the current rules: ESAs are treated as pets in the cabin, while task-trained psychiatric service dogs retain access.
Harry Reid International in Las Vegas — one of America’s busiest airports — treats ESAs as pets like everywhere else.
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 Nevada.
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.
Trains, buses, and hotels follow the ADA, which covers service animals rather than ESAs — so pet rules can apply. Your ESA letter still matters where you’ll live: short-term rentals, sublets, and leases at your Nevada destination remain covered by the Fair Housing Act.

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.
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.
