Congressmen Richard Hudson and Cedric Richmond have introduced new legislation that would restore a cap on passenger security tax in the US.
The duty imposed by the Transportation Security Administration (TSA) is at the centre of a lawsuit filed by IATA and Airlines for America (A4A).
The groups argue that the TSA has misinterpreted changes made to the fee structure last year and is overcharging passengers by imposing the fee per flight.
“Congress made this change against the backdrop of the existing round-trip cap and expected it to remain in place,” states A4A.
If passed into law the proposed bill would restore the cap. According to A4A the TSA is currently collecting more than $1bn in additional passenger security taxes.
