Luxair Luxembourg Airlines

The application at the end, while payment gives an error and exit. I tried immediately the second time, the price became higher and it gave me at the end the same error.

When trying to check in using a group booking reference or even individual e-ticket numbers issued to passengers on the same group booking, everyone in a group booking can see the confidential personal data like date of birth, passport number, etc of other passengers in the group when checkin in using this app.

The Luxair app keeps thinking I have no Internet connection, when I clearly do. Can't find my bookings, can't remember my personal details, asking me to input them again and again ;terrible app.
