CFL Telephone
CFL offers a booking hotline where FIP 50 tickets can be purchased. The hotline is available in Luxembourgish, French, German, and English.
To authenticate FIP eligibility, a photo of the inside of the FIP card for all travelers must be sent by email to callcenter@cfl.lu during the booking process. Payment is then made by credit card via a 15-minute payment link sent by email.
CFL charges a booking fee of €5 per booking.
Personal Tip
To avoid additional costs when calling abroad, you can use the Satellite app. It offers 100 free minutes per month for international calls. However, registration may take a few days.
