I think it also depends what time you are flying out. We took the first flight out to Orlando on Wednesday October 3,2007 and we waited 45 minutes in line for security. Many people in line were talking about missing their flights. We even saw two people begging the security officer at the front of the line to let them ahead because they had been paged and were about to miss their flight. The airport staff just told them, sorry you should have been here earlier.
We arrived at the airport at 5:45am for a 7:00am flight. It took us 5 minute to navigate the airport (first time flying from Buffalo) 10 minutes to check in bags, 45 minutes in security. I was worried that we would miss our flight when I saw the line. We only had about 15 minutes to spare. I am glad we had those A boarding passes!!
I am interested to find out if it is always like this on the first flight out?
