In case of buying tickets of low cost airlines: Ryanair, Wizz Air or EasyJet be sure to check in on line before your flight. An additional fee will be paid for airport check in. In most cases, free check in opens 48 hours before the scheduled flight.
If you are flying with RyanAir airline and do not have a European Union passport, you will receive on e-mail boarding pass after you check in online, which you will need to print. If you want to check in before the due date, it is necessary to make an additional payment. The company calls this a priority boarding and seat purchase.
Wizz Air, on the other hand, allows you to have boarding pass recorded on your smart phone. However, there are destinations for which online registration is not possible at all. In this case, do check in at the airport.
