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.
WestJet check-in and baggage drop closes 45 minutes before a domestic flight, and one hour before an international departure. We recommend guests arrive no later than 90 minutes prior to the departure of a domestic departure and two hours prior to an international flight. Be sure to plan extra time to get to the airport in case of traffic conditions or longer-than-expected airport lineups.
