After as many as 6,600 flights were cancelled between New York and New England since Thursday while Winter Storm Nemo swept the region, near-normal operations began to return to area airports on Monday.

Some flights had resumed this morning at JFK, LaGuardia and Newark -- and schedules were expected to continue ramping up throughout the day. Even in Boston and New England, where the storm wreaked most of its havoc, flights began to fly again, USA Today reported.

At Boston Logan, the last airport to restart operations, some flights resumed Monday morning -- and airport officials said they expected that restoration to continue throughout the day.

"Airlines will be rebuilding their schedules throughout the day, and we should be at full capacity by the end of the day," Massport spokesman Matthew Brelis told The Boston Globe. "We've had very experienced snow crews working throughout the storm, with the exception of five or six hours at the height of the storm when we had to pull."

In other areas also hard-hit by the storm, including Providence and Hartford, flights began to resume.

"We actually opened early at 5:55 (a.m.) and we had our first incoming flight soon after, and we've had our first outgoing flight at 7:10," Harford Bradley International spokesman John Wallace told The Hartford Courant. "The first incoming was around 6:30."

Storm-related flight cancellations began in the Midwest on Wednesday, USA Today reported. While FlightStats counted 6,600 cancellations, rival firm FlightAware tallied only about 5,800. It's uncertain what led to the discrepancy, according to USA Today.
