Possibly might help. On our last trip, we down loaded the VeriFLY app, it was literally like walking thru an airport. You have to get use to walking past the long lines and just showing your phone to the person at the end, once he or she sees the green VeriFLY app, they can’t wave you thru fast enough. Good luck!
We always fly first class. The last couple of trips the lines stretched down the sidewalk outside. You just need to walk up to the door and tell the attendant that you are flying first class. They will immediately wave you in. If you didn't know, you could needlessly wait in a long line.
