When you book a flight on AirlinesTicketCorp.com, we will send you an email to confirm your purchase. In that email you’ll find your flight itinerary as well as one or more confirmation numbers. You can check in for your flight at the airport by presenting a printed copy of this confirmation email to the ticket agent (along with a government-issued photo ID; if you’re travelling internationally, you will also need a valid passport).
It’s always a good idea to check your flight information 24 hours prior to your scheduled departure time, as airlines do make schedule changes periodically. You can do this either by calling your airline or by looking up your flight on their website.
