United Airlines to add 14 new nonstop routes from Chicago O'Hare in 2026

United Airlines plans to launch 14 new nonstop routes from Chicago O'Hare International Airport in 2026, the airline said. The additions cover a range of markets, from smaller regional airports to long-haul international service to Tokyo Narita Airport.

One new route goes to Santa Fe, New Mexico. That market had no nonstop Chicago service until American Airlines began flying it in December 2025. Once both carriers are operating, the Chicago-Santa Fe market will have two daily flights.

The additions are part of a broader effort by United to build up its presence at O'Hare, which the airline and others call the world's busiest airport. Aircraft assignments and exact launch dates for the 14 routes were not fully outlined in available information.

No other airlines were mentioned as adding competing service on the new routes. American Airlines remains the only other carrier named, and only on the Santa Fe route.
