United To Block Some A321XLR Middle Seats To Fly With 3 Flight Attendants, Not 4

United Airlines may be installing some peculiar-looking rows of seats in the new Airbus A321XLR’s economy section. The extra-long-range A321neo narrowbody jets can carry more than 200 flyers in higher-density layouts, but United’s XLRs that are planned to debut this summer will only be outfitted with 150 seats.
