Here's the deal: Yes, your metabolism affects your size, and the faster your personal motor runs, the more calories you'll burn. But the truth is, a slow metabolism isn't the real reason you're packing on pounds. You are the reason.
As a general rule, arrive at the airport no later than two hours before your domestic flight is scheduled to depart. This is somewhat later than the typical suggestion of three hours for an international flight.
Also because of the fear of terrorist attacks, you should be there at least 2 hours before the flight. The airlines usually expect you to arrive 90 minutes prior to a domestic and 2 hours prior to an international flight. If you're really tight on time tho, don't worry, because they usually call your name many times before departing. ultimatecanucksfan Â· 8 years ago.
