Airlines canceled more than 4,000 flights across the U.S. this weekend as heavy snow and thunderstorms snarled operations at major airports in cities like Chicago and Dallas, leaving some travelers stranded overnight.
Storms dumped more than 5.3 inches of. snow at OHare International Airport on Sunday, prompting airlines to cancel more than 1,000 flights. Those that did take off Sunday were delayed by an average delay of 44 minutes, according to the Chicago Department of Aviation. Another 189 flights were canceled Monday morning at OHare, while travelers stuck overnight on Sunday were still struggling to schedule their trips.
American Airlines said it canceled more than 1,700 flights due to the Chicago snowfall over the weekend and thunderstorms along the East Coast on Monday morning. Southwest has canceled over 400 flights since Saturday.
Overall, more than 38.5 thousand flights have been delayed since Saturday, and over 4,500 have been canceled, according to flight-tracking site Flightaware.com.
Heavy rainfall and flash flooding will exit the Northeast later on Monday, but threats of "severe" thunderstorms and some flash flooding will continue to spread across the Eastern US through Friday, the National Weather Service said.
After heavy snowstorms, Chicago temperatures are increasing and are expected to reach mid-50s on Monday and mid-to-high 60s by Tuesday, forecast models show.
