The 737 is no longer your average little jet. The 800 and 900 series both have about the same capacity as the 707-300 or DC-8-50 or DC8-8-62, the original big birds of the airlines. It can fly almost as far and, because it doesn’t have a flight engineer, has 2 less (and more efficient) engines, it can do it cheaper than a 707
As I mentioned elsewhere in the forum, the 737 has come a long ways! It was at first strictly a short to medium haul aircraft. It is possible (and has been for many years) to circle the world on a 737.
I’ll have to admit, there is no place in the world I enjoy visiting more than Switzerland, but I have never considered using this service. Does this Swiss/Privatair ZRH-EWR 738 business class-only operation make money? Can’t imagine the Swiss not figuring out how to operate anything pretty well. Sorry, I forgot, Swissair!
What makes this operation tick, given so many other business-only services kaput?
