United to swap middle seat for shared center table on select A321XLRs

United Airlines will debut Economy Plus on its new Airbus A321XLRs later this year by replacing the middle seat with a fixed center table that allows passengers on either side to share a desk (two small cup-holders, space for snacks or a travel board game). About 50 A321XLR aircraft will feature one middle-seat row with two tables, expanding elbow room for four passengers in that row. Pricing and booking details will be announced before the planes launch service domestically in the fall and internationally next year, while Polaris lie-flat suites remain available for eligible travelers.
