Public Transit & Your Service Dog: TSA, Amtrak, Metro, and Local Rules
Federal rules, state rules, and the unwritten rules transit cops actually enforce. A practical guide to riding with a service dog from Boston's T to LA Metro to the New York City Subway.
The federal framework
The ADA Title II covers all public transit operated by state or local government — buses, subways, light rail, commuter trains. Service dogs ride free, no carrier required, anywhere the public is allowed.
Title III covers private transit (Greyhound, Megabus, Lyft, Uber).
Air travel is separate (Air Carrier Access Act) — see the airline post.
TSA at airports
Service dogs go through security with you. The process:
- You and your dog walk through the metal detector together (or are wanded together)
- TSA may pat down both of you separately
- Your dog's vest, harness, and tags may need to come off
- Your dog will NOT go through the X-ray machine
Where it goes wrong: Some TSA agents try to send your dog through the X-ray (illegal — never put your dog through the machine). Politely refuse. Ask for a supervisor if needed.
TSA Cares — free service for passengers with disabilities: 1-855-787-2227. Call 72 hours pre-flight, they assign a dedicated agent to help you through security. Particularly useful for first-time service dog flyers.
Amtrak
Service dogs ride free on Amtrak. No advance documentation required for most routes (some long-haul routes request 48-hour notice for the manifest). Quirks:
- Trains have dedicated accessible seats on most cars — request when booking
- Conductors are generally well-trained
- Long-haul routes (Coast Starlight, California Zephyr) include pet-relief stops at major stations
- Service dogs in private bedrooms: free. Pets must be in carriers.
Metro systems by city
| City / System | Service Dog Policy | Common Friction | Notes |
|---|---|---|---|
| NYC Subway (MTA) | Service dogs welcome anywhere, any time, free | Rush-hour crowding | Drivers generally well-trained |
| Washington DC Metro (WMATA) | Service dogs welcome, free | Pet-vs-service confusion at gates | Carry your card |
| Chicago L (CTA) | Service dogs welcome, free | Occasional driver confusion | Most stations have accessible elevators |
| SF MUNI / BART | Service dogs welcome, free | Low — well-trained system | BART is service-dog-friendly throughout |
| LA Metro | Service dogs welcome, free | Variable | Bus drivers vary; trains better |
| Boston T (MBTA) | Service dogs welcome, free | Lower friction than most | One of the better-trained systems |
| Philadelphia SEPTA | Service dogs welcome, free | Some friction on regional rail | Local transit is fine |
| Atlanta MARTA | Service dogs welcome, free | Less consistent enforcement | Carry ID |
| Seattle Sound Transit | Service dogs welcome, free | Low friction | Well-trained system |
City buses (any city)
Same rules: service dogs ride free, no carrier required. The friction is usually with a driver who's new on the route. Calm correction usually works.
Greyhound and Megabus
Both are private interstate transit (covered by ADA Title III).
- Greyhound: Service dogs free. Book a seat with extra legroom for free if available.
- Megabus: Same. Some routes require advance notice for the manifest.
- Bolt, FlixBus: Similar policies.
What if a transit officer says no?
Transit cops in some cities (most notoriously: NYPD, BART Police, some MARTA officers) occasionally challenge service dog handlers. The script:
"My service dog [Name] is trained to [task]. She has full access rights under the ADA. Could you please verify with your supervisor?"
If they persist, document everything: badge number, time, location, exact words. File a complaint with both the transit agency and the local civilian review board.
