Do you have to print your boarding pass when you check in online?

People checking in to their flight online do not have to print their boarding pass. Most airlines provide the option of printing a boarding pass from a home computer or at the airport kiosk.

Checking in online is convenient as it helps prevent standing in a long line at the airport. Even if a passenger doesn’t print the boarding pass after checking in, she can still avoid long lines by using a kiosk to check in. Some airlines email boarding passes to a mobile device. This email contains a boarding pass bar code that the passenger can show at the security checkpoint to gain entry.
