Yes, you can check-in using the app. If you check-in with the app, you have the following options to retrieve your boarding pass:
• Visit wizzair.com, enter your flight confirmation number and print your boarding pass
• Save your boarding pass to Passbook* to have access even when your phone is offline
• Retrieve your boarding pass via the app if your phone is connected to the internet
It is your responsibility to make sure that either you have your boarding pass saved to Passbook or you have internet access at all times during the check-in and boarding process.
Some airports in the Wizz Air network do not yet support mobile boarding passes. In such cases, when you check-in using the app, a mobile boarding pass will not be generated. Please visit wizzair.com, retrieve your reservation and print your boarding card.
