United Airlines announced United Airlines A321XLR Economy Plus, a coach option on its Airbus A321XLRs that uses a row with an open middle seat and a shared table. The product will go on sale later this year, and United expects to use it on its entire order of 50 A321XLRs.
The airline says the aircraft will have 150 seats. That puts it below the 151 to 200 seats range that would require 4 flight attendants under 14 CFR §121.391, and the 150-seat configuration calls for 3 flight attendants.
United Airlines and 14 CFR §121.391
Under 14 CFR §121.391, airplanes with more than 100 seats need 2 flight attendants plus 1 additional flight attendant for each unit of 50 passenger seats above 100. United’s 150-seat plan sits at the top of the lower staffing band, while 151 seats would move the aircraft into the next band and require 4 flight attendants.
United’s natural layout for the Airbus A321XLR would have produced 152 seats in coach when paired with 20 business class seats and 12 premium economy seats. Blocking two middle seats lets the airline keep the aircraft at 4 total flight attendants instead of 5.
Open middle seats on A321XLRs
The seat is not a traditional empty middle seat. United describes it as extra elbow room with access to a shared table across the open middle seat, a setup closer to European Business Class than standard coach.
The company says the version on its Airbus A321XLRs does not include elevated catering or lounge access. That keeps the product inside coach while selling the extra space as a distinct option.
United Airlines later this year
United ended the practice of blocking middle seats next to elite frequent flyers in 2007, so the new product is not a return to that old benefit. It is a new seat design tied to the Airbus A321XLR cabin and to the staffing threshold built into CFR rules.
For travelers, the practical question is whether the open middle seat will be part of a paid upgrade or a broader seating benefit. United has said the new Economy Plus offering will be available for sale later this year, and it is also exploring these seats on other aircraft types.
The immediate takeaway is simple: passengers booked on United’s 50 A321XLRs will see a cabin built around keeping one seat unusable in selected rows, and the airline is using that layout to stay inside a lower flight-attendant count.
