TSA Service Dog Requirements

Are service dogs free to fly for people with disabilities?

Yes. Under the Air Carrier Access Act (ACAA), service dogs can fly for free with travelers who have qualifying disabilities. These dogs are not considered pets—they’re trained working animals that assist individuals with physical, sensory, psychiatric, intellectual, or other disabilities. When flying from Houston’s airports—George Bush Intercontinental (IAH) or William P. Hobby (HOU)—passengers with service animals can expect full support through both TSA screening and airport facilities.

What Disabilities Qualify for a Service Dog

According to the Americans with Disabilities Act (ADA) and ACAA, service dogs are permitted to accompany travelers who have a disability that substantially limits one or more major life activities. Examples include:

Mobility impairments (e.g., individuals who use wheelchairs or have limited walking ability)
Visual impairments (guide dogs for the blind)
Hearing impairments (hearing dogs for the deaf)
Medical conditions (such as seizure disorders or diabetes)
Psychiatric disabilities (including PTSD or severe anxiety)

Emotional support animals (ESAs) are not classified as service dogs under TSA or airline policies.

Can Service Dogs Fly for Free?

Yes, airlines must allow trained service dogs to fly in the cabin at no charge. However, passengers are required to:

Notify their airline in advance and complete any required U.S. Department of Transportation (DOT) Service Animal Air Transportation forms.
Ensure the service dog remains under control (harnessed or leashed) and behaves appropriately during the flight.
Confirm that the dog fits safely at the passenger’s feet without blocking aisles.

Both IAH and HOU airports provide designated Service Animal Relief Areas (SARAs) to make travel more comfortable for service dogs. These areas are conveniently located post-security in each terminal for easy access before or between flights.

TSA Screening for Service Animals

When going through security, passengers with service dogs will proceed through the TSA checkpoint together. According to TSA.gov:

Handlers should keep the dog leashed at all times.
TSA officers will inspect the dog’s harness and collar.
Travelers may be asked to walk through the metal detector together, or the officer may use alternate screening methods.
Treats, toys, and food for the service dog are allowed in carry-on bags but must follow standard TSA liquid and food screening rules.

TSA officers are trained to interact respectfully with service animals and will never separate handlers from their dogs.

Service Dog Amenities at Houston Airports

Both Houston airports make it simple for travelers with service dogs to navigate their journey:

At IAH: Service Animal Relief Areas are located in Terminals A, B, C, D, and E.
At HOU: A Service Animal Relief Area is located near Gate 44, across from the Interfaith Chapel.
Both airports also participate in accessibility programs to support wheelchair accessible travel, accessible travel services for seniors, and other mobility assistance needs.

Final Thoughts

Flying with a service dog is a right protected under U.S. law. As long as your dog is trained to perform tasks for a qualifying disability, you can fly for free with your service animal through Houston’s airports (IAH and HOU).

To ensure a smooth experience:

Contact your airline before travel.
Review the TSA service dog requirements.
Take advantage of Houston Airport’s Service Animal Relief Areas for your companion’s comfort.
