what about short-haul flights? Routes such as Berlin-Copenhagen seem to make sense, as in: Not as fast as a plane but faster than a train and possibly cheaper than both (using hydrogen airships). I don't know much about airships but that is what came to my mind (besides obviously the freight side of things that is being researched).
