Delta Airlines welcomes service animals aboard all flights. These animals will travel in the cabin at no additional charge. Delta adheres to the rules and regulations for service animals as set forth by the U.S. Department of Transportation. However, regardless of your chosen airline, Dogs on Planes encourages all travelers with service animals to be familiar with their basic rights and responsibilities. 

Within the U.S. Department of Transportation parameters, Delta Airlines has its own set of service animal policies that passengers should be aware of.  



Delta Airlines Service Animal Policy
Passengers traveling with trained service animals are encouraged to submit the required documentation at least 48 hours before a flight. These forms are available via the airline’s Trained Service Animal Request document. If you are traveling with a service animal, you may also be asked to show the animal’s Veterinary Health Form and/or an immunization record. Advanced notice of travel is highly encouraged but not required.  

If you’re booking a flight through Delta but notice you’ll be flying on an affiliate carrier, consult the Delta Pet Travel Connection Carrier Rules—they may differ depending on your airline.  

In accordance with a Department of Transportation ruling, Delta Airlines will no longer accept emotional support animals as service animals.

Other Types of Pet and Animal Travel with Delta Airlines 

Behavioral Expectations
Service animals are expected to be seated in the floor space below a passenger’s seat or in the passenger’s lap. These animals (and their associated items) will travel for free, but the size of the animal must not exceed the “footprint” of the passenger’s seat. Passengers are encouraged to select a seat that offers additional space. 

Delta Airlines reserves the right to refuse transportation to animals engaging in disruptive or dangerous behavior. This includes growling, jumping on passengers, relieving themselves in the gate area or cabin, barking excessively, and eating off seatback tray tables.

Delta does not permit service or emotional support animals that pose safety and/or public health concerns. This includes: 

  • Hedgehogs 
  • Ferrets 
  • Insects 
  • Rodents
