Delta Air Lines said it has now canceled about 750 flights Wednesday and Thursday due to a massive Nor'easter affecting flights in the Northeast, the Mid-Atlantic and Southeast.

The Atlanta-based airline said even more cancellations are possible, depending on the condition of airports.

Travelers should check their flight status before heading to the airport.

Delta has suspended operations at Boston Logan International Airport through Thursday, and plans to resume flights there Friday morning.
