When do I need to check in for my Wizz Air flight?

Online Check-in:

Online check-in is available from 30 days up to 3 hours before your scheduled departure.
You must present a printed boarding pass along with a valid travel document (passport or national ID) at the gate.
Passengers with ID documents issued outside the European Union are required to visit the check-in desk before boarding for document verification and to have their boarding pass stamped.
If you have checked baggage, make sure to drop it off at the baggage drop desk no later than 40 minutes before departure.

Airport Check-in:

You can choose the paid airport check-in option when booking your ticket.
The fee is 46 PLN per passenger per flight when booked in advance.
If you choose to pay for this service at the airport, a higher fee applies, usually around 140 PLN per passenger per flight.
