TSA said earlier this year that more than one million airline passengers have signed up for its Pre-Check program.
Dow said it was important that the expansion of the program is continued.
"The volume of U.S. air travel is expected to double in 20 years,” he said. “This forecast, combined with rapidly rising costs to screen passengers, underscores the need to expand trusted traveler programs such as Pre-Check, especially as our nation moves away from a one-size-fits-all approach to a more intelligence-driven, risk-based transportation security system.
"With two million travelers flying daily, Pre-Check can only succeed if participation is greatly expanded beyond the five million passengers that have currently been screened,” Dow continued. “We are encouraged by recent news that TSA is exploring new methods to expand usage of the program."
