Holiday travel could break records, experts say. Here’s what you should know

The two weekends on either side of Christmas look to be some of the most crowded times on the road and at airports.
WASHINGTON — Drivers and airline passengers without reindeer and sleighs better make a dash for it: it’s beginning to look like another record for holiday travel in the U.S.
The auto club AAA predicts that more than 119 million people will travel at least 50 miles from home between Saturday and New Year’s Day, which would top the previous holiday-season high set in 2019. The two weekends on either side of Christmas look to be some of the most crowded times on the road and at airports.
Trade group Airlines for America also foresees record travel, saying it expected U.S. airlines to carry 54 million passengers during a 19-day period that started Thursday and ends Monday, Jan. 6. The number would represent a 6% increase over last year.
A government shutdown that could start as soon as Saturday would likely be too close to the holidays to immediately affect flights and airport operations, but that might change if a shutdown dragged on.
What will be the busiest travel days?
Airlines expect to have their busiest days on Friday and Sunday, and on Dec. 26, Dec. 27 and Dec. 29. Flight traffic is expected to be light on both Christmas Day and New Year’s Day. The slowest U.S. air-travel day this year — by a wide margin — was Thanksgiving Day.
The Transportation Security Administration expects to screen 40 million passengers over the holidays and through January 2.
About 90% of Americans traveling far from home over the holidays will be in cars, according to AAA.
“Airline travel is just really high right now, but most people do drive to their destinations, and that is true for every holiday,” AAA spokesperson Aixa Diaz said.
Gasoline prices are similar to last year. The nationwide average Thursday was $3.05 a gallon, down from $3.08 a year ago, according to AAA. Charging an electric vehicle averages just under 35 cents per per kilowatt hour, but varies by state.
Transportation-data firm INRIX says travel times on the nation’s highways could be up to 30% longer than normal over the holidays, with Sunday expected to see the heaviest traffic. Boston, New York City, Seattle and Washington, D.C., are the metropolitan areas primed for the greatest delays, according to the company.
Weather and other wildcards
Because the holiday travel period lasts weeks, airports and airlines typically have smaller peak days than they do during the rush around Thanksgiving, but the grind of one hectic day followed by another takes a toll on flight crews. And any hiccups — a winter storm or a computer outage — can snowball into massive disruptions.
Many flights during the holidays are sold out, which makes cancellations even more disruptive than during slower periods. That is especially true for smaller budget airlines that have fewer flights and fewer options for rebooking passengers. Only the largest airlines, including American, Delta and United, have “interline agreements” that let them put stranded customers on another carrier’s flights.
This will be the first holiday season since a Transportation Department rule took effect that requires airlines to give customers an automatic cash refund for a canceled or significantly delayed flight. Most air travelers were already eligible for refunds, but they often had to request them.
Passengers still can ask to get rebooked, which is often a better option than a refund during peak travel periods. That’s because finding a last-minute flight on another airline yourself tends to be very expensive.
“When they rebook you, they will pay for the fare difference. If my flight to visit grandma that I booked six months ago for $200 gets canceled, and I turn around and book a flight four hours from now for $400, I have to pay that difference,” said Sally French, a travel expert at consumer-affairs company Nerdwallet.
People traveling on budget airlines with fewer flights and no partnerships with other carriers may face a difficult choice in the event of a canceled flight.
“They will put you on the next outgoing Spirit or Frontier flight, but that could be a while from now. Sometimes waiting three days for that next flight is not going to work for you,
