The flights must be incredibly uncomfortable. They are packing many more passengers into their planes[1]. E.g. that article linked to a previous one where Norwegian Air was unable to fly into Vegas during the summer, because their heavy planes couldn't legally take off in hot weather.

By comparison, United's 787-8 and 787-9 Dreamliner models seat 219 and 252 passengers, respectively. http://www.usatoday.com/story/travel/flights/todayinthesky/2016/11/17/too-hot-fly-norwegian-air-suspends-summer-las-vegas-flights/94025902/ http://www.usatoday.com/story/travel/flights/todayinthesky/2...
