How can we use the E-ticket?

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 traveling 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.
