Travelers are advised to contact your airline
prior to going to the airport (even if you already have your
boarding pass) in order to verify that your flight has not been
cancelled or delayed. This will ensure that do not arrive at
the airport only to find that you made the trip unnecessarily.
In addition, so that your airline can notify you directly
of any last minute changes, make sure that you give the travel
agency your cell phone number and home telephone number.
