Business Insider reporters toured United Airlines' new Airbus A321XLR, which will launch to Europe in December.

Taylor Rains/Business Insider We toured United Airlines' new ultra-premium Airbus A321XLR at the UK's Farnborough airshow in July.

The jet has doors in business class, privacy dividers in premium economy, and a snack bar in coach.

The A321XLR's international debut is set for December, with new routes to Europe starting in 2027.

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.
