Service Dogs on Delta Airlines: 2026 Policy Guide

Delta's Service Dog Policy Overview

Delta Air Lines accommodates trained service dogs in the cabin on all flights, in compliance with the U.S. Department of Transportation's (DOT) Air Carrier Access Act (ACAA) regulations. As one of the largest U.S. carriers, Delta's policies affect millions of passengers annually.

Pre-Flight Requirements

DOT Service Animal Forms

Delta requires the DOT Service Animal Air Transportation Form to be submitted at least 48 hours before your scheduled departure. This form includes attestations that the dog is a trained service animal, is trained to perform tasks related to your disability, has been trained to behave in public settings, is in good health, and will not need to relieve itself during the flight or can do so in a sanitary manner. You can submit the form through Delta's website or mobile app.

Booking Your Flight

When booking, indicate that you will be traveling with a service dog. This can be done online during booking or by calling Delta's accessibility line. While not strictly required, advance notice helps Delta ensure appropriate seating and a smooth boarding process.

International Travel

For international flights, additional requirements may apply depending on the destination country. These may include health certificates, rabies vaccination documentation, import permits, and quarantine requirements. See our comprehensive international travel guide for details.

At the Airport

Arrive at least 2 hours before domestic flights and 3 hours before international flights when traveling with a service dog. Check in at the counter so staff can verify your DOT form submission. TSA procedures allow you and your dog to go through the security checkpoint together. The dog does not go through the X-ray machine. You may be asked to walk through the metal detector with your dog. TSA officers may visually inspect or pat down your dog.

In the Cabin

Your service dog must fit on the floor at your feet or partially under the seat in front of you. The dog cannot occupy a seat, sit in your lap, or block the aisle. Delta does not guarantee a specific seat type, but requesting a bulkhead or window seat can provide more floor space. For guidance on flying with large service dogs, see our guide on flying with large service dogs.

Delta expects service dogs to remain on the floor at the handler's feet, be under the handler's control at all times via leash, harness, or tether, not bark, growl, or display aggressive behavior, not sniff at or bother other passengers, and be housebroken. Service dogs are allowed in all cabin classes: Main Cabin, Delta Comfort+, First Class, and Delta One.

Delta's Breed and Size Policy

Delta does not have breed-specific restrictions for trained service dogs. All breeds are allowed as long as the dog meets behavioral requirements. However, the dog must physically fit in the floor space in front of your seat.

Problems and Complaints

If you experience an issue with Delta regarding your service dog, ask to speak with a Complaint Resolution Official (CRO). Airlines are required to have one available at every airport. The CRO can resolve most issues on the spot. If unresolved, file a complaint with Delta's Customer Care department and with the DOT Aviation Consumer Protection Division. For detailed guidance, see our denied access response guide.

Frequently Asked Questions

Does Delta charge for service dogs?

No. Delta does not charge any fee for trained service dogs traveling in the cabin with their handler. The service dog flies free and does not count as your carry-on item. This applies to all cabin classes including Delta One, First Class, Comfort+, and Main Cabin.

What forms do I need for Delta?

Delta requires the DOT Service Animal Air Transportation Form to be submitted at least 48 hours before departure. The form includes handler attestations about the dog's training, behavior, and health. No veterinary documentation is required for domestic flights.

Can Delta refuse my service dog?

Delta can deny boarding to a service dog only if the dog poses a direct threat to health and safety, is not housebroken, is too large to fit in the handler's foot space without blocking the aisle, or if the required DOT forms were not submitted. Breed alone is not a valid reason for denial.
