Air travel could be snarled heading into Thanksgiving thanks to a large snowstorm poised to sweep across the country on Tuesday and Wednesday.
As a result, United and Delta have both announced waivers for some travelers impacted by this week's storm. The waivers allow travelers to rebook their flight without penalty.
Adding insult to injury, a second storm could toil with travelers following the holiday.
According to the National Weather Service, nearly a foot of snow is expected to fall in Denver, which is a major hub for United Airlines. The National Weather Service also cautioned drivers who will use Interstates 70, 26 and 76.
United Airlines announced on Sunday travel waivers for those departing from Denver now through Nov. 29.
The pre-Thanksgiving storm is then expected to travel north, where 5-7 inches of snow are expected around Minneapolis. Minneapolis is a major hub for Delta.
Delta announced late Monday waivers for those flying out of Minneapolis.
Although snow is expected to stay well to the north and west, Chicago, Indianapolis, Detroit and Cincinnati are expecting an extreme wind event. Much of the Midwest was placed under a high wind watch for Wednesday.
Another storm is expected to sweep across the Rockies and Upper Midwest on Friday and Saturday, but it is too early to predict the amount of snow.
