TSA Precheck on all connecting flights

If my fist leg of international travel is on Alaska Airlines and I have a TSA Precheck, will my connecting flight on British Airways also be TSA precheck?

We start in Sacramento, CA on Alaska Airlines, then connect in Seattle to London on British Airways.

Best Answer

Any gate at Sea-Tac is reachable from any other gate without passing through TSA security again.

You can walk between concourses A, B, C, and D, but if you are traveling to or from the N or S gates, (you should be as they serve international flights) which are in separate buildings, then you can't walk; you must take the train. You will see signs directing you to trains which you can take between concourses. When you arrive in Sea-Tac, look for signs directing you to the N & S Gates.

If you see a TSA security checkpoint from either side, you took a wrong turn. (Though you may see US Immigration on your way out.)

Does TSA PreCheck cover all airlines?

TSA PreCheck\xae is currently available at more than 200 airports with 80 participating airlines nationwide. Eligible passengers can learn where by selecting a state or by entering airport information below.

Do you have to go through TSA again for a connecting flight?

Yes, a security check is mandatory when you take a connecting flight. This is because there is a time lag between getting off one aeroplane and getting on-board another to reach your destination.

Why do I not get TSA PreCheck every time?

The most common problem is that their date of birth or government \u201cknown traveler number\u201d has been entered incorrectly into a reservation. Other times, the name on the itinerary doesn't match the name used to enroll in PreCheck, Global Entry or one of the other government programs.

Can you go through TSA PreCheck if its not on your boarding pass?

Participating airlines display a TSA PreCheck\xae indicator directly on your boarding pass if you are eligible for TSA PreCheck\xae based on your provided Known Traveler Number (KTN). If you do not have a valid boarding pass with a TSA PreCheck\xae indicator on it, you cannot access the TSA PreCheck\xae lane.
