Online check-in enables passengers to download their boarding passes to a computer or mobile device. This procedure often gives the possibility to select seats, view upgrade options, pay for baggage, and more.

It is recommended that you visit your airline's website to view their online resources while getting ready for your trip. Use online check-in if available, as this can help reduce the time you spend queuing at the airport. [Many travelers find it best to check-in online and get their boarding passes from the comfort of their rooms.]
