I actually went through this with Lufthansa last spring. I’d booked the wrong return date by accident and panicked when I noticed it the next morning. The good news is Lufthansa does let you change or cancel within 24 hours without a penalty. What helped me the most was just calling their support directly—honestly way quicker than trying to sort it out online. I dialed 877-764-3622, explained the situation, and the agent fixed my ticket in under 10 minutes. No extra fees, no stress. If you’re inside that 24-hour window, that number is hands-down the fastest way to confirm changes, cancellations, or even rebook if you spot a better time. Learned the hard way, but now I always double-check my flights right after booking!
