United Airlines is trying to attract flyers with another luxurious perk: an empty middle seat.

The Chicago-based carrier announced plans this week to roll out a new row of its “Economy Plus” seats with no neighbor in the middle spot — and instead use the space for a shared table (and more elbow room) between the aisle and window travelers.

The offering is only set to be available in one row on United’s new Airbus A321XLR aircraft, with pricing and sales expected to be disclosed later this year. But United suggested it could expand the no-middle-seat option to other planes down the road.

The move arrives amid a broader push from airlines advertising more and more special tiers and separate add-ons to their flights — particularly when it comes to courting passengers who are willing to pay more for comfort.

United is following the footsteps of a handful of European airlines, including Lufthansa and Finnair, already offering empty middle seats to business class passengers. And other carriers have also allowed travelers for years to pay extra or buy additional tickets to keep seats near them empty.
