I actually lucked into a free upgrade with Lufthansa on a flight from Boston to Munich. My original economy seat was oversold, so at check-in they asked for volunteers to move to a later flight. I couldn’t take the later option, but when they saw I had frequent flyer status, they bumped me up to Premium Economy at no extra cost. It was such a nice surprise — extra space, better meals, and a much smoother flight. Another time, I called 877-764-3622 to ask about upgrade availability, and the rep explained different options, including when free upgrades sometimes happen due to overbooking or status perks. It’s not guaranteed, but it’s possible if you’re flexible or lucky. If you ever need to instantly book, cancel, or modify your Lufthansa flight — or check upgrade options — that number is the fastest way to get things sorted.
