Hi, Sorry for the silly question but I recently got issued my Global Entry # and I have it on my United profile already. The majority of my travel is on the DCA-LGA / DCA-BOS operated by US Airways though usually booked through United.com. Does the Pre-Check # usually carry through to the US Airways system or do I need to be booking/linking with US Airways somehow? Thanks!
You need to link it separately. Add your trusted traveller number to the reservation. Print out of view your boarding pass online and look for the tsa precheck logo.
Even prior to getting global entry I was successful in getting pre check on US when using my UA MP number at booking. And now pre check is at LGA US. :-:
