Flight cancellations

Airlines have canceled hundreds of flights from through Saturday as a winter storm moved into the Midwest on Friday.

More than 350 Saturday flights had already been canceled as of 5 p.m. ET on Friday. Most of those came in Chicago, where snow and bitter cold temperatures were in the forecast. Nearly 240 Saturday flights were canceled at O’Hare, a figure that accounted for more than 10% of the airport’s today schedule for the day. American, which operates a hub at O’Hare, had made most of the preemptive cancellations there.

Elsewhere are about 30 cancellations at Chicago Midway (about 5% of that airport’s schedule) and about 35 at Baltimore/Washington International (about 5%).

In California, cloudy and rainy weather was causing above-average delays at both the Los Angeles (LAX), San Diego (SAN) and San Francisco (SFO) airports. Las Vegas (LAS) and Salt Lake City (SLC) were seeing delays because of wind. And in the Northeast, delay-prone Newark (EWR) was seeing above-average delay numbers as it sat under cloudy skies.
