United Airlines' newest Airbus jet is easily the airline's fanciest narrowbody yet.
Adorned in a blue-and-white livery and packed with 150 new luxe seats, the Airbus A321XLR underscores United's continued push to court higher-paying travelers as demand for greater comfort grows.
Most notably, sliding doors are now offered in Polaris business class — an increasingly common feature in newer premium cabins and something long requested by many of United's most valuable flyers.
Meanwhile, during a tour of the jet at the UK's Farnborough International Airshow in July, Peter Wolkowski, United's director of onboard products and partnerships, told Business Insider that premium economy is particularly popular these days.
"It's that nice buy-up from economy, where you can get more space and nicer amenities, as well as that opportunity to rest," he said. "We are making a conscious effort to increase the size of the new Premium Plus."
Coach also got upgrades, including a self-service snack bar and "extra elbow room" seats for an added fee, a sign the airline is investing in economy, not just its highest-paying customers.
On Tuesday, United announced that its first international A321XLR routes will be from Washington Dulles to Amsterdam and Dublin, beginning December 1, 2026, with tickets going on sale Thursday. The airline plans to use the aircraft on five all-new routes to Europe starting in 2027.
It will replace aging Boeing 757s, mostly on transatlantic routes. With its up to 11-hour range, the jet is well-suited for far-flung Europe routes because it can reach destinations that don't have enough demand for a widebody but are too far for most other narrowbodies.
Here's what passengers can expect onboard.
The A321XLR will launch in December, with new routes to Europe slated for spring 2027.
After flying select domestic routes from September and then making its international debut in December, United said the A321XLR will fly five all-new routes to Europe next year.
Service from Newark, New Jersey, to Luxembourg is expected to begin in April, followed by Ibiza in May, and Marseille and Valencia in June. It is also set to fly from Washington Dulles to Toulouse starting in April.
Business class is essentially a mini living room.
The 20 large business-class loungers each convert into a lie-flat bed up to 78 inches long, with a 19-inch television, a remote control, several charging ports, a cubby, and Bluetooth connectivity.
Closing the door cocoons the seat into a cozy, private little suite.
Wolkowski said the design underwent two rounds of overnight sleep trials, with customers spending the night in a mockup of the new seat while experiencing simulated service from flight attendants.
"Every part of the layout, the detail, everything you see, is very thought out and intentional," he said. "From the labeling to the control panel being right at your fingertips."
The privacy doors weren't easy to certify.
The doors' added complexity during emergency evacuations created certification challenges, and the A321XLR requires an additional flight attendant.
Wolkowski said that the A321XLR doors are fully certified and will not be locked open at launch.
Unlike the A321XLR, United's new Boeing 787 Polaris privacy doors were locked open at launch but can now be closed after the Federal Aviation Administration certified the design in early August.
Premium Plus is now more private.
United added a large privacy divider between the window and aisle seats in its upgraded premium economy cabin, and there are no middle seats on the narrowbody A321XLR.
The 12 plush, deep-reclining loungers also have a 16-inch seatback screen, a footrest and legrest, extra table space, and elevated linens and meals.
Premium economy demand is booming.
Wolkowski said premium economy is increasingly popular with flyers as a cheaper yet amenity-rich middle ground between coach and lie-flat business.
He said Premium Plus is the fastest-growing cabin on the company's 787s.
Coach has Bluetooth connectivity and Starlink.
United has been offering Bluetooth on select planes for years, so it's no surprise the A321XLR got the feature.
The airline is also rolling out Starlink across its fleet; it has launched on regional jets and some 737s and 777s.
Economy has a self-serve snack bar.
United removed several rows of coach seats to add a snack bar in the back galley.
The walk-up perk, already on the airline's CRJ550 and A321neo, will be available to all passengers, who can expect complimentary items like water, soda, and chips.
The entire cabin has custom mood lighting.
Wolkowski said United developed custom lighting scenes to help passengers combat jet lag by illuminating the cabin in specific hues during specific phases of flight.
For example, a blue-and-white scene, intended to resemble shooting stars, is for boarding. There are also darker hues for bedtime, and orange and pink hues for daytime and meals.
Bigger overhead bins mean fewer gate checks.
United said its A321XLR will feature larger overhead bins designed by Airbus as part of its Airspace XL cabin. These will accommodate more roller bags and reduce gate-checking during boarding.
The same bin design is already in service on United's A321neo aircraft.
