I reckon it could work. But it would have to be sustainably run with slow growth initially. It would be a much bigger risk than buying a lot of 737's. You'd have to find a jet that is able to run from Germany to USA. That jet would be used on all LH operations to keep costs low. Staff would be put up in houses owned by the airline. They would clean and cook for themselves. No hotels. Only 3/4 bases in Europe, strategically situated such as London, Madrid and somewhere in Germany and or France. Cheap fares offered to travel to these bases with Ryanair. Options to buy dinner when booking ticket and selected seating an added cost. The planes will have entertainment but you will pay for it. This model will differ in that it won't ever be free. During slacker months fares will be higher and always cheaper than main operators.... Going to the loo will be free but toilet paper and soap added extra. Showers on board an option.... A bar area provided by drink supplier that pays rent to use the area. Cargo operation also to help cover costs.
