      First, please check if your question is answered by the following Q&A. Additionally, our customer service team can always be reached at support@flex.lu or via the hotline (+352) 2883 3882.

      It’s very simple; start the old Flex app on your smartphone and confirm the message for the update. If this message does not appear, please uninstall the old app and simply search for the “FLEX Carsharing” app in the Apple App Store / Google Play Store on your smartphone and download it.

    • What needs to be updated to make a booking with the new FLEX App?

      As soon as the new app is ready, each customer will receive an activation link by email. This will allow existing account data (e.g. bookings) to be automatically transferred by users. They will then be asked to enter a new password. Important: existing credit card information will not be transferred and must also be entered again.

    • What happens to my already created bookings that were planned for the period after the update?

      Confirmed reservations from 11.03. onwards will automatically be transferred to the new app. However, to be on the safe side, please check this again.

      Please navigate to the customer portal at www.flex.lu via Login. At the top right of your profile, select a suitable location. All vehicles available at the station will be displayed there.

      Customers who booked a liability reduction for 50€ 7 months ago will automatically receive a travel credit of 25€ on their Flex account.

      This credit can be activated and used in the booking process in the payment step under “Redeem discount code”.

      Existing travel credits will be transferred to the new system. The credit can be activated in the booking process in the payment step under “Redeem discount code”.
