An amendment adopted by the Senate to the FAA bill would prohibit airports from using passenger facility charge revenue to build bike storage facilities.
The amendment was offered by Sen. John McCain, R-AZ, and approved by unanimous consent as part of a manager's package.
"Most airline passengers would agree with me that they would rather see more improvements to ensure faster travel times and safer departures and arrivals," McCain said on the Senate floor.
That provision is also likely to be debated during a conference committee with the House as several key representatives, including House Transportation and Infrastructure Committee Chairman James Oberstar, D-MN, are major supporters of bicycling.
"This is just providing another mode of transportation option to people who travel to and from the airport," said Oberstar spokesman Jim Berard. He noted bike parking racks at airports are especially useful given the nation's emphasis on reducing the use of fossil fuels.
