But who knows, if it's cheap and more comfortable than flying, maybe people will see the trip as part of the experience.
Something more akin to a recliner that I could actually sleep in, enough legroom, a place to put a laptop that wasn't hunched over and awkward and maybe enough room to get up and stretch for more than 3-5min at a time.
I don't know if it would be feasible to make a really wide, fat winged lifting body dirigible that you can put a huge amount of solar cells on top of but if you could do that and also make it somehow go ~150mph you're getting pretty close to 1/3 the speed of an airliner with the added advantage that you might not need anywhere near as much fuel.
I go from Texas to Florida semi-regularly There's 2-4 hours of pre and post flying travel and sitting around plus about 2-2.5 hours of travel for a total of 4-6 hours of total travel time. If the flying time went to more like 6 hours and you kept the pre and post travel flying times the same it wouldn't make a huge impact on me. I might actually ask if they could slow the "plane" down so that I could make it an overnighter and hopefully get enough sleep!
