If you forgot to enter your membership number during the booking process, you can add it later.

You can enter your Miles & More service card number after booking but prior to departure by logging into your flight or your profile. If your flight is not displayed under "My Bookings", your number can also be entered by our staff at the check-in counter. You can of course also enter your Miles & More service card number after you have boarded your flight. You will find the form for adding mileage credit after your flight at miles-and-more.com.
