Important 2026 update: Spirit Airlines has stopped flying
Before anything else, you need the most current fact: Spirit Airlines ceased all operations on May 2, 2026. After filing for bankruptcy protection twice since 2024 and failing to secure a federal rescue deal, the ultra-low-cost carrier began an orderly wind-down, cancelled every remaining flight, and moved into liquidation. As reported by NPR, CNN, and CNBC, it was the first shutdown of a major U.S. airline in roughly 25 years. Spirit's customer service lines are no longer staffed, and its fleet is being sold or returned to lessors.
That means there is currently no active Spirit Airlines service dog policy you can book under. If you searched this term to plan a trip, the practical next step is rebooking with another carrier (covered below). We're keeping the policy details on this page for two reasons: many handlers still have disrupted Spirit itineraries to sort out, and Spirit's rules were a textbook example of how the federal Air Carrier Access Act (ACAA) works at every U.S. airline. Your underlying rights did not disappear with Spirit.
What to do if you had a Spirit booking with your service dog
If your trip with your service dog was cancelled by the shutdown, here is a calm, ordered checklist:
- Request a refund through your card issuer. With the airline in liquidation, a credit-card chargeback for the unused fare is often the fastest path to your money. Keep your confirmation email and any DOT forms you already submitted.
- Rebook on a still-operating airline. Frontier, American, Delta, United, JetBlue, Southwest, and Alaska all carry trained service dogs free of charge. Compare them in our airline service dog policy comparison chart.
- Re-submit the DOT form to your new carrier. Forms you sent to Spirit do not transfer. Each airline collects its own copy.
- Don't let a gate agent reclassify your dog as a pet. In the rebooking scramble, this is exactly when handlers get wrongly charged a pet fee. Have your dog's task list, training facts, and a quick-to-show profile ready.

How Spirit's service dog policy worked (and why it still matters)
Spirit's policy mirrored federal law almost exactly, which makes it a useful reference for whichever airline you fly next. Under the ACAA and Spirit's rules, a service animal meant a dog of any breed individually trained to do work or perform tasks for a person with a disability. Emotional support animals were not treated as service animals and were subject to the regular pet fee — a distinction the DOT cemented in its 2021 rule. If that affects you, read emotional support animal vs. service dog.
The key points of Spirit's service dog policy were:
- Service dogs flew free in the cabin with no pet charge and were exempt from the pet carrier size limits.
- Up to two service dogs per handler were allowed. A third dog would be treated as a pet under the standard policy.
- Staff could ask the two questions permitted by law — is the dog required because of a disability, and what work or task has it been trained to perform. They could not ask about your diagnosis or demand a demonstration. See the two questions explained.
- The dog had to be harnessed, leashed, or tethered at all times in the airport and on the aircraft, and behave under control.
The foot-space rule, explained
The detail handlers searched most was Spirit's foot-space rule — and it's identical to what other airlines enforce, so it's worth understanding well. On Spirit, your service dog had to:
- Stay within your own foot space (the floor area in front of your seat).
- Not extend into another passenger's foot space.
- Not extend into the aisle, which is a safety and evacuation requirement.
- Never occupy a passenger seat. The dog rode on the floor or, if small, in your lap.
For a larger service dog that couldn't fit one footwell, Spirit let you buy an extra seat for additional floor room — the dog still stayed on the floor, never on the seat cushion. This is the single biggest planning issue for big dogs, so read how to fly with a large service dog. The general rules for in-cabin placement are covered in service dog airplane seat rules.
The DOT forms Spirit required (and most airlines still do)
Spirit required the U.S. DOT Service Animal Air Transportation Form, the standardized government form attesting to your dog's health, behavior, and training. The handler-completed details matter: the Department of Transportation treats this as a federal document, and false statements can carry penalties. Spirit asked handlers to submit it online, generally at least 48 hours before departure, with one form per reservation and per dog if traveling with two.
Two nuances from DOT that apply industry-wide:
- The 48-hour rule cuts both ways. An airline cannot require advance submission if you booked within 48 hours of the flight — it must let you hand in the completed form at the gate.
- Long flights need a second form. For flights of 8 or more hours, DOT also requires a Service Animal Relief Attestation confirming your dog can relieve itself in a sanitary way or not at all.
Don't guess on the paperwork. Our step-by-step guide to filling out the DOT form walks through every field so your submission is accepted the first time.
Flying a different airline now? Make your service dog impossible to misclassify.
With Spirit gone, you'll be rebooking on a new carrier — exactly when gate agents wrongly ring up pet fees. ID is never legally required, but a verifiable ServiceDog Profile with QR check and ID card lets you show your dog's trained tasks in one tap, so you clear the counter free and fast. Create your profile in minutes at /dashboard?tab=register — pay only when you're ready to unlock your ID card and certificate from $39.

Here's the contrast that mattered most at the counter. On Spirit, a regular pet cost roughly $125 each way (per carrier), with the pet plus soft carrier limited to about 40 lbs combined and the carrier capped at roughly 18" x 14" x 9". A trained service dog, by law, paid none of that and faced no size cap.
The problem isn't the law — it's the moment a busy or undertrained agent looks at your dog and starts ringing up a pet fee. That mistake happens across every airline, especially during disruptions like a mass rebooking. The strongest defense is being able to calmly and quickly present that this is a trained service dog: state the task it performs, keep it under control on a leash, and have something visible to back you up. Read how to present your service dog, and how to file a DOT complaint if a carrier wrongly charges or denies you.
| Item | Trained service dog | Pet (or ESA) |
|---|---|---|
| Cabin fee | Free | ~$125 each way |
| Size / weight limit | None | ~40 lb combined, fits 18x14x9 carrier |
| DOT form required | Yes | No |
| Rides in carrier under seat | No — at your feet / in lap | Yes — must stay in carrier |
Where to rebook your service dog now
Since Spirit is no longer flying, you'll need a new carrier — and every major U.S. airline carries trained service dogs free under the same ACAA framework, so your rights travel with you. Frontier Airlines is the closest like-for-like to Spirit's ultra-low-cost network and pricing, which makes it the natural first stop for former Spirit routes.
- Frontier — closest match to Spirit's budget pricing and network.
- American, Delta, and United — full-service majors with the widest route maps.
- JetBlue and Southwest — strong domestic coverage and easy DOT-form portals.
- Alaska and Hawaiian — reliable West Coast and island options.
Whichever you pick, your day-of routine is identical: submit the DOT form, arrive early, find an animal relief area, and clear TSA screening with your dog leashed and under control.
Your rights are the same on every U.S. airline
It bears repeating, because Spirit's collapse can make handlers feel like the rules reset: they don't. The ACAA, enforced by the DOT, governs every U.S. carrier and most flights touching the U.S. A trained service dog flies free in the cabin, the airline may ask the two task-related questions, your dog must stay leashed and under control within your foot space, and the airline may require the DOT form once per trip (not per leg). On the ground, the ADA, administered through the Department of Justice, protects you in the airport terminal and at your destination — hotels, restaurants, and rideshares.
One thing the ADA is crystal clear about: there is no official U.S. service dog registry, and no law requires you to register, certify, or carry ID for your dog. Any site claiming a mandatory "national registration" is selling something you don't legally need — we cover the scam in service dog registration scams.
Why a verifiable profile still smooths the counter
So if ID isn't required, why bother? Because rights and friction are two different things. Legally you can fly with nothing but your dog's training and a completed DOT form. Practically, when an agent is moving fast — or when a whole planeload of stranded Spirit passengers is being rebooked at once — the handlers who clear the desk fastest are the ones who can show, not just argue.
A digital service dog profile with QR verification lets you hand over one tap that displays your dog's name, photo, handler, and trained tasks. It is 100% voluntary and never replaces the law — but it answers the agent's question before it escalates into a wrongful pet fee or a denied boarding. Think of it as a friction-reducer, not a permission slip, and it's especially worth it if you fly often or travel with a large dog. You can start your profile in minutes and only pay when you're ready to unlock your ID card and certificate.
Frequently Asked Questions
Is the Spirit Airlines service dog policy still in effect in 2026?
No. Spirit Airlines ceased all operations on May 2, 2026 and entered liquidation, cancelling every flight. There is no active Spirit service dog policy to book under. Rebook with another carrier such as Frontier, American, Delta, United, JetBlue, or Southwest — all carry trained service dogs free under the same federal ACAA rules.
Did service dogs fly free on Spirit Airlines?
Yes. While Spirit operated, a trained service dog flew free in the cabin with no pet fee and no size limit, unlike pets, which cost about $125 each way and had to fit a small under-seat carrier. That free-travel right comes from the Air Carrier Access Act and still applies on every U.S. airline.
What was Spirit's foot-space rule for service dogs?
Your service dog had to stay within your own foot space and could not extend into another passenger's foot space or into the aisle. The dog never occupied a seat — it rode on the floor or, if small, in your lap. For a large dog you could buy an extra seat for added floor room. Most airlines enforce the same rule.
Do I still need the DOT service animal form to fly?
Yes, for most carriers. The U.S. DOT Service Animal Air Transportation Form is standard across U.S. airlines and is usually submitted online at least 48 hours before departure (or at the gate if you booked within 48 hours). Flights of 8 or more hours also require a relief attestation form. The form you sent Spirit does not transfer — submit a fresh copy to your new airline.
Is a service dog ID card required to fly?
No. There is no official U.S. registry and no law requiring registration, certification, or an ID card for a service dog. A digital profile, QR verification, or ID card is entirely voluntary — but it can speed you through the counter and help prevent your dog from being wrongly charged as a pet during a busy rebooking.
