Record rush off to a smooth start

The late crush of holiday travelers is picking up steam, with about 2.7 million people expected to board flights on Wednesday and millions more planning to drive or take the train to Thanksgiving celebrations.

Airline officials say they are confident they can avoid the kind of massive disruptions that have marred past holiday seasons, such as the meltdown at Southwest Airlines over last Christmas. And as of mid-day Wednesday that appeared to be the case. U.S. airports were reporting only five flight cancellations and 364 flight delays, according to Flightaware, a tracking service.

But snow showers could still snarl traffic in some parts of the country. The National Weather Service was predicting accumulating snow in northern New England Wednesday, including up to 8 inches (20.3 centimeters) of snowfall in northern Maine. Snow was also expected to hit the northern Rocky Mountains on Thanksgiving Day, bringing up to 1 foot of snow to parts of Wyoming by Friday.

Security lines at airports could be long. Delta Air Lines is telling passengers to arrive at the airport at least two hours before their flight if they are traveling within the United States, three hours early if they’re flying overseas — and maybe earlier on Sunday and Monday.

The Transportation Security Administration said it screened more than 2.6 million passengers Tuesday and it expected another 2.7 million passengers to come through airport security on Wednesday. On Sunday, it expects to screen 2.9 million passengers, which would surpass a previous record set on June 30.

Lines ebbed and flowed all morning Wednesday at Moynihan Train Hall in New York. Some travelers said they opted to travel by train for convenience or lower prices. Others said they just wanted to avoid any chaos at the airport.

Matthew Hudnall and Abby Greenbaum were traveling from Atlanta to New York to Boston to visit family with their 5-year-old daughter. By the time they reach Boston, they will have taken a total of nine trains, they said.

“I think we thought it would be calmer and less stressful than flying. So, far that’s true,” Greenbaum said.

Amtrak said passengers could see some boarding delays because of high passenger volumes this weekend. The holiday will also test the Federal Aviation Administration, which faces shortages of air traffic controllers at key facilities that caused reductions in flights to the New York City area this summer and fall.

U.S. Transportation Secretary Pete Buttigieg said during a news conference Monday that the government prepared for holiday travel by hiring more air traffic controllers, opening new air routes along the East Coast and providing grants to airports for snowplows and deicing equipment.

Airlines have also added tens of thousands of employees in the last couple of years, and Southwest says it bought more winter equipment to keep planes moving even during sub-freezing temperatures.

AAA predicts that 55.4 million people will travel at least 50 miles from home between Wednesday and Sunday, the third-highest forecast ever by the auto club. AAA says most of them — 49.1 million — will drive.
