E ticket is a document you receive after making an online purchase on our site. You don’t have to print it, it’s enough to have it in your mobile phone. It is important that you know the ticket number.
If you do available online check in for traditional airline, you don’t need to print it but you do need to have it in your mobile. If you do check in at the airport, the desk clerk will hand you a paper boarding pass. Be sure to keep it as you need the document to board the plane (with your passport of course). You can also get a boarding pass at the airport’s interactive machine if you check in for a flight.
The procedure for boarding pass at low cost airlines carriers is different. Take special care if you fly with RyanAir. They are explicit that travellers who do not have an EU passport must print a boarding pass. You check that printed document at the airport at the RyanAir company counter. Also desk representative checks if you need a visa for the country in which you are travelling for. After that a stamp and signature are placed on the boarding pass. With a certified document you can board on a plane.
On the other hand, Wizz Air does not require the printing of a boarding pass. With them, it is not possible to check in online for certain destinations at all. In this case, the flight check in is done at the airport and you get a boarding pass there.
