What exactly are the criteria for taking non-elite companions through the priority late at TSA checkpoints? I've taken plenty of with me when they were traveling on the same flight. This weekend my gf and I are heading from SEA to LAS with another couple. She and I have elite status with UA, but they do not and are traveling on a separate AS flight. AS and UA are right next to each other at SEA, so I figure I should at least try to give them some benefits of my status and get them through security faster. SEA is also has some of the nicer TSOs. Am I setting myself up for embarrassment as they turn my friends away, or will all of us be able to get in the line together? My feeling is that we're still traveling "together" even if we use different planes past security.
