Airlines have already started issuing wide-ranging change fee waivers to allow flexible travelers the opportunity to reschedule their flights to avoid the mess.While the winter storm is expected to dump snow in the Rockies Thursday, it’ll pick up strength as it sweeps eastward. By the time it hits Maine, more than three feet of snow is expected in parts of the state.Image courtesy of Weather Underground.However, it’s not just the snow forecast that’s expected to impact travel. Harper will bring very strong winds to the region – dropping the wind chill and wreaking havoc on air travel.Airlines are preparing for this storm by issuing weather waivers. Travelers with plans to fly during the storm may be able to change their flights to an earlier/later date or route through another airport that isn’t expected to be affected by the storm.Through 9:30am ET Thursday, only four airlines have issued weather waivers so far.
