United Airlines put tickets on sale today for nonstop flights to cities that currently have no United service, including Luxembourg City and Okinawa.
In an August 25, 2026 announcement, the airline called the package its largest international expansion yet: 10 new cities for 2027, three extra routes to cities it already serves, and a San Francisco to Tel Aviv restart, with government approvals still required.
- Sale date: Tickets are available now on united.com and the United app.
- New cities: Ten destinations join the map in 2027, eight of them exclusive among U.S. airlines.
- Earliest starts: San Francisco to Okinawa and Los Angeles to Osaka begin March 27, 2027.
- Europe hubs: Most new European cities launch from Newark between April and June 2027.
- Caveat: Every new route remains subject to government approval.
What United put on sale today
United’s August 25 newsroom release lists 10 first-time cities for the airline: Okinawa, Toulouse, Luxembourg City, Marseille, Ibiza, Valencia, Terceira in the Azores, Ljubljana, Olbia in Sardinia, and Catania in Sicily.
Eight of those cities will have no other U.S. airline nonstop, according to United. That exclusivity claim is why Luxembourg and Okinawa matter immediately for trip planners who previously needed a connection or a foreign carrier.
Simple Flying independently tallied the European schedule from Newark, Denver, and Washington Dulles and noted that six of the European airports will regain or gain U.S. nonstops after long gaps. Use that reporting for context, and treat United’s release as the booking authority for dates and aircraft.
The 10 new cities and when they start
San Francisco to Okinawa opens the calendar on March 27, 2027, with three weekly Boeing 777-200ER flights. Newark to Luxembourg follows on April 2 as a daily Airbus A321XLR route.
Washington Dulles to Toulouse starts April 26 on the A321XLR. Newark then adds Ljubljana on May 12, Olbia on May 27, Catania on May 28, Ibiza on May 31, Valencia on June 2, Marseille on June 4, and Terceira on June 9.
Frequencies range from three weekly flights on thinner leisure routes to daily service on Luxembourg, Toulouse, and Marseille. Aircraft mix spans the A321XLR, Boeing 767s, a 777-200ER, and a 737 MAX 8 on the short Azores hop.
Those details come from United’s published table. Schedules can still move before summer 2027, so confirm the live offer in the app before locking hotels or park tickets around a specific inbound day.
Extra routes to places United already flies
Beyond the 10 new cities, United is adding Los Angeles to Osaka as daily service from March 27, becoming the only airline to serve Osaka from two continental U.S. cities alongside San Francisco.
Washington Dulles gains three weekly Milan Malpensa flights on May 28, restoring a city pair United last flew in 2003. Denver gets a new daily Paris Charles de Gaulle nonstop beginning May 27 on a Boeing 787-9.
San Francisco to Tel Aviv is scheduled to restart March 28 with three weekly flights. United says that restart will offer the most business-class seats between the two cities of any airline once it begins.
United also says summer 2026 European additions from Newark to Split, Bari, Glasgow, and Santiago de Compostela return for summer 2027. Those repeats are not new cities, but they matter if you already planned around last year’s seasonal calendar.
Why the A321XLR is part of the story
United is using the Airbus A321XLR to open thinner European markets that do not justify a widebody every day. The airline says the type will fly Ibiza, Luxembourg, Marseille, Toulouse, and Valencia among the new destinations.
The same aircraft debuts international service on December 1, 2026, on Washington Dulles flights to Amsterdam and Dublin. Tickets for those first international XLR sectors go on sale Thursday, August 27, two days after this route package.
Cabin features United highlights include United Polaris suites with privacy doors, Economy Plus seats with an open middle and shared table, Starlink Wi-Fi for MileagePlus members, and more premium seats than the Boeing 757-200s the XLR is meant to replace on selected long thin routes.
For travelers comparing long-haul products, Deep Arrival’s United Airlines guide remains the place to check bags, elite access, and cabin names before you choose a fare brand on a brand-new city pair.
How to decide which new route is worth booking now
If your trip depends on a city that only United will serve from the United States, buying early protects inventory more than it protects a fare. Exclusive markets such as Luxembourg, Toulouse, Okinawa, and Terceira can thin out peak-summer Polaris and Premium Plus seats first.
If Denver to Paris is the draw, compare United’s May 27, 2027 daily nonstop with existing United Paris flights from Newark, Dulles, Chicago, and San Francisco, plus other U.S. carriers already selling 2027 Paris seats. The new DEN flight is about hub convenience, not inventing Paris access.
If you are watching Japan, Okinawa and the new Los Angeles to Osaka flight sit beside United’s existing Pacific map. Confirm aircraft and cabin before assuming Polaris density matches a 777 or 787 long-haul you already know.
Related Paris competition already includes Alaska’s planned Seattle to Paris flights and Delta’s Austin to Paris launch, covered earlier on Deep Arrival at the Alaska Seattle Athens and Paris guide and the Delta Austin Paris nonstop report. Those posts are chronology, not substitutes for United’s August 25 booking window.
What is confirmed, inferred, and still open
Confirmed today: the city list, start dates United published, aircraft assignments in the release, ticket availability on united.com, and the statement that routes need government approval.
Supported interpretation: United is using the A321XLR and existing widebodies to chase secondary European leisure cities and deepen Japan and Paris coverage from West Coast and Rocky Mountain hubs. That reading matches the route mix United published.
Still unknown: final approved schedules, exact introductory fares by cabin, how rival carriers respond on Olbia and Catania, and whether any announced city slips after regulatory review. Do not treat a screenshot from today as a forever schedule.

United framed the day as network breadth for every trip stage, from business to honeymoon to visiting family. For travelers, the usable fact is simpler: new city pairs are searchable today, with March through June 2027 start dates already on the calendar.
