United Airlines is planning to configure its new Airbus A321XLR aircraft with blocked middle seats in economy, according to multiple aviation reports. The approach is intended to allow the airline to staff the flights with fewer flight attendants than its standard configuration. One account describes United’s plan as flying with three attendants rather than four, using the blocked seats to create a reduced seating pattern. The reports say the concept resembles a European-style business or premium cabin seating layout, where unused seats can help preserve a wider passenger spacing. Both sources frame the blocked-seat arrangement as a way to make better use of the aircraft’s cabin layout and potentially convert the middle seats into a sellable “extra space” product, rather than leaving them permanently unused. The information discussed relates specifically to United’s A321XLR fleet and the onboard staffing and seating configuration changes associated with it.
