I finally flew Lufthansa Business Class on a trip from Chicago to Frankfurt, and it was a huge step up from economy. The lounge access was the first perk I noticed — quiet space, free food, and showers before the flight. Onboard, the lie-flat seat made the overnight trip so much easier, and the amenity kit had all the basics I needed. They don’t hand out pajamas like in First Class, but the service, meals, and wine selection felt really special. Wi-Fi was available for a fee, which I used to catch up on emails mid-flight. I originally wasn’t sure if the upgrade would be worth it, but after calling 877-764-3622, the agent explained the options and helped me switch using miles and a little cash. If you ever need to instantly book, cancel, or modify a Lufthansa flight — or check upgrade perks — that number is the fastest way.
