What is an e-ticket?
An e-ticket (electronic ticket) is a non-physical ticket required by the airlines to allow passengers to fly. The e-tickets are issued by either a travel agency or an airline when a booking has been confirmed and paid.
Note that your e-mail trip confirmation is not your e-ticket and you should always make sure that the e-ticket has been issued by checking your online itinerary at www.tripcase.com. We do also send the E-ticket to you, when the ticket is issued, this sometimes ends up in your spam-folder, so please keep an eye there as well.
What if I lose or forget to bring a print of my e-ticket?
You will be registered in the airline's system and you need to show a personal ID like your passport. Bringing a print of your e-ticket is however strongly advised.
You should be aware that some airports will not let you in unless you can document you actually have a flight to catch. In those cases it's always recommended to have a print or some other way to document that you actually are flying out so you don't have to argue with security or to contact the airline.
