Transportation Security Administration fees are doubling Monday, and frequent travelers will notice a slight hike in their airfares.

The TSA fee is currently $2.50 per non-stop flight and $5 per connecting flight, but the new fee will be $5.60 for all flights, and any connection over 4 hours counts as a separate flight.

Congress approved the new fee in December in order to raise $12.6 billion to cut the deficit, and the TSA estimates the fees could raise $16.9 billion.

“It’s like paying for a root canal,” George Hobica, founder of airfarewatchdog.com, told USA Today. “It’s something you didn’t want anyway. Now you’re paying more for it.”

While the fees go into effect today, frustrated travelers can send comments to the TSA until Aug. 19.
