I had to cancel a Lufthansa flight from Chicago to Frankfurt last year, and I was nervous about the fees. What I learned is that Lufthansa’s cancellation policy depends a lot on the fare type. Flexible tickets usually allow free cancellations, but the cheaper economy ones often come with a fee or just a credit instead of a refund. In my case, I had booked a semi-flex fare, so I got most of my money back minus a small fee. To avoid confusion, I called 877-764-3622, and the agent broke down exactly what I’d get back and processed the cancellation right away. The whole thing took less than 15 minutes, and the refund hit my card in a few days. If you’re ever unsure about Lufthansa’s cancellation policy or need to instantly book, cancel, or modify a flight, that number is by far the quickest way to sort it out.
