My main reason for saying I'm using my US passport as that's the one that's linked to my Global Entry membership and so provides TSA-Pre.
If I told United I was using my UK (or French) passport, would I still be able to have TSA-Pre outbound?
For departures, TSA Pre√ keys of the Known Traveler ID and not passport. For inbound to US, you’ll want to use the passport that has GE.
