I ran into Lufthansa’s booking classes when I booked a trip to Munich and saw all these codes like “K” and “Z” on my ticket. At first, I had no idea what they meant. Later, I learned they determine things like fare rules, upgrade eligibility, and mileage earning. For example, my “K” fare was one of the cheaper economy options, so it had stricter change rules and earned fewer miles. A friend of mine had a “Z” fare in Business Class, which was fully upgradeable and flexible. I got confused trying to figure it all out online, so I just called 877-764-3622. The agent explained what my fare allowed and helped me decide whether paying a little more for a flexible ticket was worth it. If you ever need to instantly book, cancel, or modify a Lufthansa flight — or understand booking codes — that number is the easiest way.
