As a record number of people in the United States prepare to travel for Thanksgiving, three storm are lining up to disrupt the rush with snow and rain.
AAA expects a record 82 millionpeople to travel at least 50 miles from Tuesday to Dec. 1. The National Weather Service is urging travelers to check forecasts and brace for delays.
Airports will feel the strain, too. Tuesday is expected to be the busiest air travel day this week, with 52,185 forecast flights,according to the Federal Aviation Administration.
And even though the government shutdown has ended, travelers should expect wait times at airports.
"Even with having all our staffing back, there's going to be wait times," Reiko Walker, who has been a Transportation Security Administration agent for 20 years, told NBC News on Sunday.
Walker, who works at George Bush Intercontinental Airport in Houston, calls Thanksgiving week "our Super Bowl."
