48 hours before your flight, make 2 important phone calls. Call the airlines and your ground transportation to reconfirm. For domestic flights, I recommend that you reconfirm all flights prior to departure and at each point of stopover. This will give the airline the opportunity to keep you advised of any changes which may have occurred in your flight. For International flights, I recommend that you reconfirm your continuing or return reservations at least 72 hours prior to flight time at each point of stopover. Make sure you know your airline’s cancellation policy.
