Flying with a service dog in 2026: the form, the fees (none), and what airlines still get wrong
Five years after the 2021 DOT rule, flying with a service dog is simpler than it gets credit for. One form per flight, free cabin access, no fees. Here's exactly how it works, plus the airline-by-airline notes our handlers report back to us.

When the 2021 DOT rule landed, it caused a lot of anxiety in the assistance-animal community — most of it, it turns out, misplaced. Five years on, flying with a service dog is genuinely simpler than the average pet-flight: one form per flight, free cabin access, no carrier needed.
We've been tracking how the rule plays out at the gate since the day it took effect. Here's the current state of things, including which airlines still misapply it.
The rule, in one paragraph
A service animal under the ACAA is a dog individually trained to perform tasks that mitigate a disability. ESAs are not service animals under the rule — they're treated as pets. The handler completes a one-page DOT Service Animal Air Transportation Form 48 hours before the flight (or at the gate for trips booked under that window), and the dog flies in the cabin at no fee. For flights longer than 8 hours, some airlines also require a separate "relief attestation" form.
That's it. Same form, same process, on every U.S. airline. The DOT publishes the official version; airlines have to accept it.
Practical flight-day workflow
Here's what we tell handlers to do, in order:
A few days before the flight
Submit the DOT form through the airline's accessibility portal (every U.S. carrier has one). Some accept it via email; some require a web upload. Confirm receipt.
Pack the harness, not a carrier
You don't need a kennel, carrier, or cargo arrangement. The dog will be at your feet (or in your lap if under ~65 lbs) for the entire flight. Pack a working vest if you have one — not legally required, but it makes pre-board interactions cleaner.
Arrive early
Aim for 90+ minutes before departure on a domestic flight, longer for international. The TSA pet-relief area is past security at most major airports — you'll want time to take the dog through it before boarding. Pack a small bag with a foldable water bowl, treats, and waste bags.
At pre-board
Most airlines pre-board passengers with disabilities; service dogs are part of that. Approach the gate agent calmly with your dog and your printed/saved DOT form. The standard interaction:
Agent: "Confirming you have a service dog with you?" You: "Yes, I do. The DOT form was submitted on [date]; I have a copy."
Some agents will ask the two ADA-style questions ("required because of a disability?" / "what task?"). Some won't. Either is fine — the questions are short, and the right answers are unchanged from any other public-access situation.
On the plane
The dog goes at your feet (in the floor space in front of your seat) or in your lap. Other passengers around you may be curious; politeness defuses most of it. A working vest signals "don't approach my dog" without you having to say it.
Airline-by-airline notes (from handler reports through 2025)
These reflect our handlers' field reports, not formal airline policy. Treat as context, not gospel.
American Airlines
Generally smooth. The DOT form integrates into their booking-management portal — submit it there, get a confirmation email, you're set. Gate agents are well-trained.
Delta
Best-in-class on the rule. Their accessibility team responds within hours, the form intake is simple, and gate agents almost never go beyond the two questions. The most consistent positive feedback we hear.
United
Reliable but slower on the form intake — submit 72+ hours before departure if you can. International routes through their European partners (Lufthansa, etc.) can have inconsistent gate experiences; allow extra time.
Southwest
The DOT form intake is via a customer-service phone call rather than a portal. Calling 48-72 hours before is usually fine. Gate agents are friendly; the boarding process (open seating) means your seat choice matters — aim for a bulkhead row for the legroom.
JetBlue
Accessibility team is responsive, form process is web-based, gate experience is generally smooth. We've had a few isolated reports of agents asking questions outside the two-question scope; politely redirecting to the rule has resolved every one.
Alaska
Strong. Their pet-friendly reputation extends thoughtfully to service-dog handling. Smooth on Pacific Northwest routes.
Spirit and Frontier
Budget carriers tend to be more rigid on documentation — they're used to charging for everything and the "free" service-dog cabin access can throw their gate agents. Submit the DOT form well in advance, print a copy, and be patient with the slightly more bureaucratic intake.
International carriers
Outside U.S. airspace the ACAA doesn't apply. EU regulations, Canadian rules, and bilateral treaties all govern instead. For most major destinations the practical reality is similar (service dogs in cabin, no fee), but the paperwork varies. Your origin airline will usually walk you through the destination requirements during the form-submission process.
When airlines still get it wrong
The most common 2026 mistake is asking for a "service-dog certification" beyond the DOT form. This is not allowed under the rule — the form is the only documentation an airline can require. If a gate agent insists on something more:
"The DOT form is the documentation required under 14 CFR § 382. There's no additional certification under the federal rule. My dog meets the service-animal definition; she performs the task I noted on the form."
If the agent persists, ask for a customer-service supervisor. Document name, time, and what was said. The DOT takes ACAA complaints seriously and the airline's compliance team will react quickly to a formal one — in our experience, a single well-written complaint with names attached resolves the issue and produces a written apology within a week.

What about ESAs?
On most U.S. carriers, an ESA flies as a pet — pet fee, carrier under the seat, weight limit. A few airlines kept some ESA-friendly accommodations after the rule change; check airline-by-airline before booking. Latin American carriers and a few smaller U.S. ones still treat ESAs differently from pets.
Important detail: a dog can be both an ESA and a service dog if it meets the task-trained criteria. Airlines look at the dog's status, not the paper. If your dog has trained tasks tied to your disability, fly as a service dog regardless of any ESA letter you also hold.
NSAR's documentation packet
Our service-dog registration includes a pre-filled DOT form template in the welcome packet — every section walked through, ready for your signature. Not legally required, but it cuts out the busywork of figuring out what to write. Same for our PSD letter customers.
The short version
One form, 48 hours ahead, free cabin, no carrier. Your dog at your feet for the flight. Most U.S. airlines have this dialed in by 2026; the few who don't will fold under a polite "the DOT form is the only documentation under the rule" and a follow-up complaint if needed.
Travel was a real source of stress for service-dog handlers before 2021. It still has its moments. But on the whole, the rule is a net win for the people the law was written for — and we're grateful for that on every flight.
