I have a question similar for my son, who is an AS MVP returning from Europe on an award ticket via MIA to SEA arriving 10:09PM so earliest SEA/PDX he could book was 6am next day. If he gets in early, he is in first with no bags so can get off the plane fast can he get the 10:30 739 or the 11:00 Q400 on standby? He will have cleared customs in MIA.
