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.
If youâre traveling on an international flight, or with children, or have a disability or medical condition that could impact travel, please arrive an additional 30 minutes before your flight. If someone is dropping you off at the terminal, or youâre not checking a bag, youâll need a little less time.
