Actually the seats aren't too bad on most planes. For sure nicer than LH Kont-C unless you get a seat with lots of legroom. LH should bring back the Kont-F they had until the early 90s to provide both a good seat and reasonable service
IŽd much rather have it our way....middle seat empty gives me a more spacious feeling than US domestic F wider seats but jam packed. And the in the air and on the ground experience "differs", too...
