If you have ever been on SQ
19 or 20 and the new EWR SIN
routes you will find out that ultra longhaul is quite nice. Try Emirates ultralonghauls.
I am excited for my first trip on EWR
on the 28th and feel more comfortable on that plane in raffles or exec econ than I do F class UAL domestic.
People do get up and walk around, and people do chat with each other. Your limited experience flying ultra longhaul routes is obviously coming into play here.
20,000+ km ranges does not make sense, as you cannot find two major points in the world that would cover this distance that you would have any market operating service on.
20+ hours is the same story, no points exist with demand for longhaul service, so that obviously slipped your mind, as it makes no sense at all.
Speed up the plane? Fly supersonic over land? That's another great idea of yours. Actually, lets make sure the routes go right over your house so you can experience the sounds along with "speeding up the plane". Remember that joint BA
/SQ concorde? Flying over land supersonic is a wonderful idea.
Try a real longhaul flight, 18+ hours, and use that time to think about some of those things you said.
