I actually tried Lufthansa’s bid-for-upgrade system on a flight from New York to Frankfurt last year. A few days before my trip, I got an email inviting me to place a bid for Premium Economy or Business Class. I wasn’t sure how much to offer, so I called 877-764-3622 to double-check how it worked. The agent explained the process: you enter the amount you’re willing to pay, and if your bid is accepted, you get the upgrade. I put in a mid-range bid for Business Class, and two days before departure, I got the confirmation that it went through. It was amazing — lie-flat seat, great meals, and lounge access — all for less than the standard upgrade price. If you ever want to instantly book, cancel, or modify a Lufthansa flight, or get help understanding upgrades, that number is the fastest way to do it.
