It's usually pretty calm... but I've never flown out on a high-travel day. Ok. Be there by seven. But don't stress.
Traveling with She-who-needs-ritalin is always a trial, but often funny, too. Her idea of getting to the airport two hours early means leaving her house two hours before the flight. It's an hour (+/- traffic) to the airport from our area. Then after screeching about how late we are when we're stuck in the security line, she'll take time to check out the shops on the way down to the gate.
