The weeks surrounding Christmas and New Year's are historically peak travel periods, but three dates in particular are set to see extra volume this year, according to the TSA.
December 1 became the busiest day ever in TSA history as the agency processed 3.09 million travelers, capping off one of the busiest Thanksgiving travel periods on record.
TSA Administrator David Pekoske said at the Skift Global Forum Wednesday he was "100% confident" that at least one airport would be under the program in 2025.
Clear, which rose to popularity by allowing flyers to speed through long security lines with its use of biometrics, will now be the third enrollment provider for TSA Pre-Check.
