Yes, you can fly with your service dog in the cabin at no extra charge, provided it meets federal requirements under the Air Carrier Access Act (ACAA).
The U.S. Department of Transportation (DOT) defines a service animal for air travel as a dog (regardless of breed) that is individually trained to perform tasks for a person with a disability. Emotional support animals are no longer recognized as service animals and must travel as pets.
Key requirements (current as of 2025):
Airlines may require you to submit the official DOT Service Animal Air Transportation Form (attesting to the dog's health, behavior, and training) up to 48 hours in advance if your booking allows it.
For flights 8 hours or longer, an additional DOT Relief Attestation Form is required (confirming the dog won't relieve itself or can do so sanitarily).
The dog must fit at your feet, under the seat, or on your lap (without protruding into the aisle) and remain harnessed, leashed, or tethered.
No vest, ID, or certification is required, though many handlers use them for smoother experiences.
Airlines cannot deny access based on breed alone.
At the airport (TSA screening):
You and your dog can often go through together; gear (vests, harnesses) is screened separately.
Additional pat-downs or inspections may occur if needed, but you won't be separated.
Practical tips: Book directly with the airline's accessibility desk for best seating. Use airport pet relief areas (indoor/outdoor patches available at most major airports
