Thanks for all the replies. I applied for Global Entry but unfortunately I won't have the card in time. My question concerning the priority security line seems to remain unanswered - is there a priority security line for those traveling in first class and/or have AAdvantage Platinum status but who don't have NEXUS or GE? Fortunately my flight is in the afternoon so I won't have to deal with what appears to be chaos in the early morning.
