A possible increase in the Transportation Security Administration (TSA) security tax has aviation industry organizations feeling dizzy. And they're getting proactive to tell Congress and travelers that this is a bad idea.

Airlines for America (A4A) has formed a coalition with other groups such as the Air Line Pilots Association (ALPA) and the Global Business Travel Association (GBTA) to urge Congress not to close the proposed budget deal, according to Airlines.org.

A joint letter was sent out on Nov. 20 to House and Senate Budget Committee Chairmen Paul Ryan (R-WI) and Patty Murray (D-WA) warning of the dangers of such a hike.

The airline industry expects the security tax on non-stop flights to double (similar to prior proposals).

So that means that where you're paying $2.50 in security tax for each leg of a non-stop flight. So you'd pay $10 for the roundtrip, instead of the $5 travelers currently pay. 

Multi-leg trips would be unaffected and remain at $10 total for the roundtrip.

“Raising taxes is lose-lose for airlines, passengers, jobs  and our overall economy. It’s inappropriate for Congress to use airline passengers as an ATM when it needs more money,” said A4A President and CEO Nicholas E. Calio.

“Doubling the TSA passenger security tax would cost passengers more than $730 million annually, placing a huge additional tax on the traveling public, with no direct benefit to those who pay it.”

In the letter, the associations and alliances acknowledged that this tax may be put in place because of the large budget deficit, but stressed that taxing passengers more wasn't a practical way to do it.

The letter notes that consumers are already paying roughly 20 percent of taxes and fees on a $300 round-trip ticket. This represents a greater tax for the consumer than through the alcohol or tobacco industries.

In 20 years, annual taxes and fees have increased from $3.7 billion to $19 billion, according to the letter.

And while Airlines for America acknowledges that the tax is designed to strengthen security, the trade organization notes that the proposed tax wouldn't do its job, instead needlessly charging passengers more.

“There is no question TSA is adequately funded to fulfill its commitment to the security of the traveling public,” Calio said. “This is strictly a revenue raiser to close a budget deal and it should not be done on the backs of airlines and their customers who are already paying much more than their fair share.”

The coalition has set up the website StopAirTaxNow.com to allow consumers to contact Congress concerning the tax.

Members of the coalition gathered at Ronald Reagan International Airport Monday to hand out air sickness bags to members of Congress returning to Washington from their holiday break.
