A winter storm prompts flight cancellations in the northeast US.

Airlines had canceled more than 2,000 flights Friday as a powerful nor'easter brought rain, snow and severe wind to much of the Mid-Atlantic and Northeast. Most carriers were waiving change fees for fliers there.

Nationwide, 2,130 flights had been canceled and another 550 delayed as of 9:35 a.m. ET, according to flight-tracking service FlightAware.
