Thanks. This makes sense to some extent, but then why wouldn’t it be printed on all boarding passes within the reservation on that basis? In my case, TSA PRE was printed on my IAH-LHR and LHR-IAH passes, but not on my LHR-ABZ or ABZ-LHR ones. Does it only get included only on boarding passes that include a US city?

If you have a connection on the same reservation after arriving in the US, surely it’s the boarding pass for the connecting flight that is the important one, which should have pre check indicated on it in any case? Just trying to understand how you would use your LHR-US BP during a US domestic connection, after that international segment was flown.

Sorry for all the questions, still learning all these ins and outs.
