We are flying out AJ from JFK June 13, 2010 at 6:00am. I am a little concerned about the switch from AJ to Caribbean. From what I read though on the AJ site, it should be fine...no worries. my biggest concern i guess is the crowds and i heard there are many delays, especially with 1 runway closed for construction. Any experiences or thoughts?? We already plan to get there very early. What does Terminal 4 look like? How is security there? is it long lines and just utter chaos? I'm hoping that the time we are leaving will help us avoid the mass confusion and chaos.
