Fliers won't suffer disruptions as severe as the ones from Christmastime storms that brought flights to a halt at several major airports. But, passengers scheduled to fly today (Jan. 28) should brace for problems in the Midwest and East Coast.

Flight-tracking service FlightAware says more than 400 U.S. flights have been canceled so far today, with the majority of those coming at airports experiencing poor weather from today's storm.

And, as has become the norm during poor weather, nearly every major airline is waiving change fees for fliers schedule to fly into the storm's path. The policies come with significant fine print, but - generally - they allow customers to make one change to their itineraries without having to pay change fees or any differences in fares.

Cancellations
The hardest hit as of 8 a.m. this morning are the New York City-area airports, where 146 departures and arrivals have been canceled at Newark Liberty and 79 at New York LaGuardia.

At Toronto's Pearson International, where snow and ice were being reported as of 8 a.m. ET, 96 flights had been canceled as of early morning, according to FlightAware.

Other airports seeing notable cancellation totals as of 8:15 a.m. ET: Chicago O'Hare (30), Minneapolis/St. Paul (26), Detroit (25), Washington Dulles (22) and Washington Reagan National (21).

Delays
Fliers whose flights aren't canceled could be hit with delays. FlightStats, another flight-tracking service, shows "significant" and "excessive" delays at a half-dozen airports (as of 8:30 a.m. ET) in the Midwest, Northeast and mid-Atlantic.

Flights bound for Philadelphia and Toronto are being delayed by an average of 75-80 minutes, according to the Federal Aviation Administration's delay map. And, of course, late arriving planes mean delays are likely for many departures as well.

Delays and continued cancellations remain a significant risk for much of the day - especially at the delay-prone airports of Newark Liberty, New York LaGuardia and Philadelphia.

To the north, freezing rain and drizzle are expected to develop after 5 p.m. ET in Boston and other parts of New England. Depending on the severity of the icing, that could mean problems for flights at Boston Logan and other airports in the region if the forecasts are accurate.
