Thanksgiving air travel did not reach the record highs of 2019, but it was close. About 2.3 million people passed through Transportation Safety Administration checkpoints Wednesday, more travelers than on any other day during the pandemic.

The figure was more than twice the total on the Wednesday before Thanksgiving last year and about 88% of the number of travelers who flew on the same Wednesday in 2019.

Social media was abuzz with nearly equal complaints about the longest airport lines people had experienced in years and surprise that lines were so short, reinforcing the idea pandemic unpredictability persists.

Among the travelers sharing a sense of excitement about being able to visit family this Thanksgiving was Katie Thurston of San Diego, known to some as the Bachelorette from Season 17 of that reality show.

“To go back to something that feels normal makes me feel so emotional,” she said in a telephone interview after tweeting about her tearful reaction to landing in Seattle to visit her mother and sister and meet her baby niece for the first time.

Hundreds of airport food service workers picketed Wednesday at San Francisco International Airport over a dispute involving health care. But contrary to some passengers’ fears — and warnings from the Southwest Airlines pilots union in August — there were no walkouts by flight attendants or pilots.

Typically, the busiest days for air travel during the Thanksgiving period are the Tuesday and Wednesday before the holiday and the Sunday after it, according to a TSA spokesperson. United said that the airline expected the Sunday after Thanksgiving to be its busiest day since the pandemic began.
