Because the majority of the people in those seats are business travelers and they’re paying for a convenient schedule. Their employers are likely paying for it and many of those employers have negotiated discounted prices in exchange for a certain volume. I’m in DC and I know a lot of people who travel to London Monday- Friday every week for work, paying j fares of $10k-$13k toundtrip for work. They get on the plane in dc fall asleep then wake up in London and go to work. They don’t care about all the stuff people complain about endlessly here, and the ua seats, even the dreaded 2-4-2 , are comfortable and enable sleep. These are the people who drive the paid j business. Not those who come here and complain endlessly about certain service standards while traveling on upgrades or deep discounted j class tix.
