Get ready to pay more for your flights because starting next week, there will be an increase to the TSA September 11 Security Fee. It’s not a huge increase but something worth noting if you travel frequently or travel with a family. Effective July 21, 2014, the September 11 Security Fee will be increased from $2.50 per flight segment with a $5.00 cap to $5.60 per ONE Way with NO cap. On the surface, this increase doesn’t seem like a big deal but the fee structure gets a little more convoluted.

Flying domestically (not including to Alaska and Hawaii), if your itinerary has a layover of 4 or more hours, the flight segment after the layover will be considered a separate trip and will add another $5.60 fee to the cost of your ticket. Each subsequent layover of 4 hours or more will result in an additional $5.60 fee.

Flying internationally or to Alaska and Hawaii, the layover limit is more lenient with a maximum of 12 hours before an additional $5.60 fee will be added to the cost of your ticket. Each subsequent layover of 12 hours or more will result in an additional $5.60 fee.
