close video Christmas snowstorm: Travel tips from expert Jeff Hoffman

Global Entrepreneurship Network chairman of the board Jeff Hoffman advises how to prepare for a potential holiday travel nightmare on ‘Varney & Co.’

Flight cancelations are top of mind for holiday travelers as a harsh winter storm is expected to hit a large swath of the U.S. 

More than 799 flights in, out of and across the U.S. have been delayed as of 6 a.m. ET on Friday, according to flight tracking website FlightAware. Nearly 3,051 have been canceled, the data shows. 

On Thursday, more than 10,028 flights in, out of and across the U.S. were delayed and nearly 2,539 were canceled.

Heavy snow, ice and strong winds are among the conditions expected from Thursday to Saturday in various parts of the country, stretching from the Plains and Midwest all the way to the East Coast. On top of that, forecasters expect severe cold during the holiday weekend. 

Airlines have proactively issued travel waivers to help travelers whose flights are canceled during a certain stretch of the holiday. This means travelers won't have to pay any change fee or fare difference when rebooking their flight.

However, it's important to read the fine print. Passengers need to book within a certain time frame and buy a seat in the same cabin. They must also rebook the same cities they were previously flying between. Impacted travel dates will differ depending on the area of the country. 

The Department of Transportation's new online dashboard, which launched just ahead of Labor Day, shows what kinds of guarantees major domestic airlines offer for disruptions due to circumstances within the airline’s control.
