Over the Christmas break I'm flying from YYC-ATL with a layover in IAH. Will go to a hotel in IAH for the night and re-clear security in the morning. I have NEXUS. Would I be eligible for PRECheck on the IAH-ATL leg?

as best as it can be assumed, Precheck is determined by the TSA on a flight-by-flight basis, so there really is no telling.

Hard to tell as the start date for NEXUS members has not come yet so no actual examples. Technically its an international itin so might not be available.

I believe its trip by trip basis. Out of all my experiences with Pre-check, every single segment clear or every single segment does not clear. Never a mix of yes and no.

No. You are not eligible if any segment is international.

It certainly would be a mix if, for example, some of the flights are on airlines that don't yet participate in the program.

Thanks for the info.

NEXUS members are all eligible for PreCheck. You use the PASSID on the back of the card.

Kind of interesting how that works.

There's nothing on the checkpoint signage that indicates it's only for domestic itineraries. I don't recall anything in the airline emails about that either.

A couple months ago, at SEA (again, sigh). At that time, Pre-check and elite lanes were side by side, led to two side-by-side TDCs. I'm in the elite lane, no one at the pre-check TDC, so she motions me to step up. She checks my BP/DL, then says 'Pre-check is only eligible for domestic itineraries'.

Mildly annoying because 1) Her manner was downright snotty, 2) She summoned me to her podium (five or six feet from the 'elite' podium, so it should have been clear to her that I wasn't claiming Pre-check eligibility and 3) no airport signage and none of the various emails I received ever mentioned the domestic flight restriction, so why would she assume I should know it? (I do, but only because of FT).

You are eligible for the program being in NEXUS but no international travel will be cleared on PreCheck, is my understanding
