How many hours before your flight do you arrive at the airport?
Thanks to everyone for answering! There were a lot of interesting replies.
I'm about 2 hours, but I've got a wide variation -- from 3 hours to 1 hour plus a few seconds.
I usually aim for 2 hours, but I don't always get it right. I also make the mistake of thinking that I need to be on the *grounds* of the airport 2 hours ahead of time, rather than *checked in with baggage dropped off* 2 hours ahead of time.
Especially if I have a rental car, this can be a big difference.
@evan I'm with you - 2h before leaving my ride is fine, through security more than 1h before departure is what I aim for.
