Air travelers faced travel headaches Monday as wintry weather pulled out of the Midwest and springtime storms fired up around airports in the Northeast. 

Nationwide, 1,085 flights had been canceled and a whopping 6,963 delayed as of 11:05 p.m. ET, according to flight-tracking service FlightAware

Most of Monday’s problems came in the Northeast, where long delays popped up at airports in New York, Philadelphia, Washington and Baltimore as thunderstorms and torrential rains moved across the region. 

Conditions eased around Washington and Baltimore as the storms moved east by late morning, but the New York, Philadelphia and Boston airports saw major disruptions into the evening.

The problems in the Northeast follow another round of major flight disruptions that snarled airports in the Midwest during the weekend. About 2,000 combined flights were canceled Saturday and Sunday as a late-season blizzard forced airports like Minneapolis/St. Paul and Sioux Falls, S.D., to suspend flights for extended periods of the weekend. 

Conditions in the Midwest had improved by Monday, but fliers should expect some residual flight irregularities as airlines get their planes and crews back into place there.
