Travelers who waited until the last day to make their Thanksgiving holiday treks need to be prepared for busy highways and the most crowded day yet this week at the nation’s airports.

The Transportation Security Administration expected to screen 2.9 million people on Wednesday and more than 3 million Sunday, when many holiday revelers plan to return home.

Air travelers had reason to give thanks — only a couple dozen U.S. flights had been canceled by late morning on the East Coast, according to FlightAware.

However, more than 1,000 flights were running late, reflecting the tendency toward tardiness that is becoming normal at U.S. airlines. Airlines were averaging more than 4,500 late flights per day since last weekend, and Wednesday’s count was likely to approach or surpass that number by nightfall.

Wednesday afternoon was expected to be the worst time to travel by car, according to forecasters. Drivers headed out of town will be mixing with commuters unlucky enough to be working on the day before the holiday.

Accidents compounded the heavy traffic. A dump truck that struck a bridge over Interstate 95 in Delaware closed the highway for several hours, according to the Delaware Department of Transportation.

Weather is the wild card

An Arctic blast in the Midwest and wet weather in the Eastern U.S. could disrupt travel over the next several days.

From Wednesday into early Thursday, mixed precipitation was expected to stretch from northern Arizona through the Plains and upper Midwest into Pennsylvania, New York and parts of New England, according to the National Oceanic and Atmospheric Administration. A chilly, sloppy mix was expected to linger into Saturday in parts of the Northeast.

Forecasters expect clear weather over most of the western two-thirds of the country on Thursday and Friday, but rain and possibly thunderstorms are predicted for the Southeast, which could raise the risk of flight disruptions.

Thanksgiving, by the numbers

Auto club and insurance company AAA predicted that nearly 80 million Americans would venture at least 50 miles from home between Tuesday and next Monday, with most of them will traveling by car.

Drivers should get a slight break on gas prices. The nationwide average price for gasoline was $3.07 a gallon on Wednesday, down from $3.25 at this time last year.

Airfares, however, are about 4.1% higher than they were a year ago, according to government figures.

The Transportation Security Administration expected to screen 18.3 million people at U.S. airports during the same seven-day stretch. That would be 6% more than during the corresponding days last year but fit a pattern set throughout 2024.

The TSA expects the biggest crowd on Sunday, which could break the record of 3.01 million set on the Sunday after the July Fourth holiday.

FAA staffing shortage could create delays

TSA Administrator David Pekoske said his agency is ready, with its highest staffing ever, but an ongoing shortage of air traffic controllers at the Federal Aviation Administration could cause flight delays.

FAA Administration Administrator Mike Whitaker said last week that his agency likely will use special measures to deal with shortages at some facilities.

“If we are short on staff, we will slow traffic as needed to keep the system safe,” he said.

In the last two years, similar measures have slowed down flights in New York City and Florida.

The FAA has long struggled with a shortage of controllers that airline officials expect will last for years, despite the agency’s lofty hiring goals.

Turkey on the plane

TSA says it’s OK to bring turkey, stuffing and other favorite holiday foods through airport checkpoints, although liquids such as gravy and cranberry sauce can’t exceed 3.4 ounces.

Just because you can carry it on the plane doesn’t mean you should.

“Especially when it comes to gravy, I wouldn’t want that in my carry-on luggage, and I definitely wouldn’t want it in my checked baggage,” TSA spokesperson Lorie Dankers said.

Thanksgiving brings out infrequent flyers, and they often have questions about what they can bring on the plane. The TSA app and website have lists of items that are banned or restricted.

Drive time

Wednesday afternoon was expected to be the worst time to travel by car before Thanksgiving, but it will be smooth sailing on highways Thursday, according to transportation analytics company INRIX.

On the return trip, the least-congested times to drive will be before 1 p.m. Sunday and before 8 a.m. or after 7 p.m. Monday, the company said.

In metropolitan areas like Boston, Los Angeles, New York, Seattle and Washington, “traffic is expected to be more than double what it typically is on a normal day,” INRIX transportation analyst Bob Pishue said.
