Yes, you can absolutely change your Lufthansa booking within 24 hours — I actually did this a few months ago when my travel plans suddenly shifted. I had booked a round-trip flight from Munich to New York but realized right after payment that my return date clashed with a work meeting. I went straight to Lufthansa’s website, logged into “My Bookings,” and used the Manage Booking option to modify my flight. Since it was within 24 hours of purchase, the change was free — no cancellation or rebooking fee at all. The confirmation email arrived almost instantly with the updated itinerary. If you ever need to adjust, cancel, or rebook quickly, doing it online through Lufthansa’s official site or contacting their customer service hotline is the fastest route. It’s super convenient and saves the stress of waiting on hold or paying unnecessary fees later.
