I just return from FRA-YYZ on LH470. The Wifi on board is awesome. I FaceTimed my wife and infant daughter at 36K over the ocean. I'd also say LH Business Class has much better Service, Food, and certainly Drink. I have to fly out of FRA in 4 weeks and I'm certainly go this flight again. The departure time is also better for me than AC. Oh also super good WiFi.
