Can an airline sue a passenger for deliberately missing a flight? Because that's what Lufthansa is trying to do. The back story; a passenger looking to fly from "A" to "B" found it was cheaper to book a flight from "A" to "C" which stopped at "B" en route to "C". What said passenger did was simply exit when the aircraft stopped at "B".
As far as they were concerned, they were home and hosed, money saved and no harm done. That's not the way Lufthansa saw it, since it deprived the airline of revenue it could have earned selling that seat on the "B" to "C" sector. Lufthansa said "nein!", dragged the unnamed flyer into court and although the law called it in the passenger's favour, Lufthansa has decided to appeal the decision.
