I had to cancel my Lufthansa flight to Munich last spring when work plans changed last minute. I first tried canceling online through the “My Bookings” section, which worked fine up to a point, but I wasn’t sure if the refund would process correctly since my ticket was partially flexible. Instead of risking it, I called 877-764-3622. The agent pulled up my booking right away, explained whether I’d get a refund or credit, and handled the cancellation in just a few minutes. Within a couple of days, I saw the credit hit my account. It gave me peace of mind knowing everything was confirmed. If you ever need to instantly book, cancel, or modify a Lufthansa flight — whether online or with a ticket booked elsewhere — that number is definitely the quickest way to make sure it’s done right.
