I don't know much about planes, but the most recent generation of planes are so very nice indeed. Especially that 787 with the low cabin air pressure. I sat on a 15 hour +/- flight from Singapore to San Francisco, in coach, full flight, and the air quality helped contribute to significant less stress during the entire flight than I used to experience in older generation aircraft. Sailing is very peaceful, there's a nice quietness and solitary quality to it. Flying can have a similar feeling to it too!
