United Airlines has added 10 new domestic destinations for flights departing O'Hare International, an expansion the US major says was enabled by the addition of five new gates allocated to it by the city of Chicago. The Chicago-based carrier notes that the Illinois city reallocates airport gates annually. It adds that gates are reallocated based on how many O'Hare flights each carrier flew in the prior year. In full-year 2024, United operated the most flights departing from and arriving at O'Hare, with 352,383, followed by American Airlines (255,061 flights) and Delta Air Lines (27,476), Cirium schedules data shows. Flights commence in 2026 for United routes connecting O'Hare with Santa Barbara and Monterey, in California; Eugene, Oregon; Paducah, Kentucky; Lynchburg, Virginia; St George, Utah; Rochester, Minnesota; Wausau, Wisconsin; Marquette, Michigan; and Idaho Falls, Idaho. "United is already flying its busiest schedule in history at O'Hare, and now these additional gates have unlocked new opportunities to intertwine cities across the country, serve more customers in Chicago and strengthen our hometown hub," states Patrick Quayle, senior vice-president of global network planning and alliances, for United.

Brunei's department of civil aviation has granted the Chinese-manufactured Comac C909 type certification. The type certification covers ARJ21-700 (C909's former name) and its converted freighter, business, medical and emergency variants, according to a type certificate acceptance report dated 22 October. The certification comes on the heels of Brunei's civil aviation authority accepting the design standards of the Civil Aviation Authority of China on 18 October. With the type certification, Brunei is poised to be the fourth country outside China to operate the regional jet. Startup carrier GallopAir has a letter of intent with Comac to purchase 30 aircraft, with confirmed orders for 15 C909s and 15 convertible orders for the regional jets and C919s. Indonesia's TransNusa and Lao Airlines operate five and two of the type, respectively, while VietJet previously wet-leased a pair of C909s from Chengdu Airlines.

Alaska Airlines is resuming flights late on 23 October after a temporary ground stop that was triggered by an IT outage, its second in four months. Alaska Air Group says in a statement that its airline "experienced an IT outage that affected operations. A temporary ground stop was put in place for Alaska and Horizon. The ground stop was lifted at 11:30 pm Pacific [time]". It has delayed a third quarter earnings call that was scheduled for 24 October "to allow our teams to focus on supporting our guests and the recovery of our operation". Reports indicate the ground stop was requested around 15:30 Pacific time for all Alaska Airlines and Horizon Air flights, but those operated by sister carrier Hawaiian Airlines and partner SkyWest Airlines were not affected. Alaska has issued a general waiver, allowing passengers booked on 23 and 24 October free rebooking up to 27 October. The airline is likely to face significant disruption as it resumes its schedule. Cirium schedules data shows that prior to the outage, it was scheduled to operate 743 flights on 24 October. The latest issue follows another IT outage on 20 July that forced it to ground flights for around three hours.
