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.
How long in advance should you arrive at an airport for an international flight? 2 hours is the general guideline. You should definitely be there AT LEAST 90 minutes in advance for an international flight - things can and have gone wrong with booking, secâ¦urity, etc.
