I would like to make a reservation but I don't know my return date yet.
Enter an approximate return date with a fictitious landing time.
Once you know your return date and landing time, go back to your customer area (on the website) and modify your booking. How do I change my booking?
Tips: We advise you to take out the modification option, so that you don't have to pay modification fees unnecessarily. Why should I get a modification/cancellation option ?
