First two hours, now three hours — this is how far in advance authorities are
recommending people show up to catch a domestic flight, at least at some major U.S.
airports with increasingly massive security lines.
Americans are willing to tolerate time-consuming security protocols in return for
increased safety. The crash of EgyptAir Flight 804, which terrorists may have downed
over the Mediterranean Sea, provides another tragic reminder of why. But demanding too
much of air travelers or providing too little security in return undermines public support
for the process. And it should: Wasted time is a drag on Americans' economic and private
lives, not to mention infuriating.
Last year, the Transportation Security Administration(TSA) found in a secret check that
undercover investigators were able to sneak weapons — both fake and real — past airport
security nearly every time they tried. Enhanced security measures since then, combined
with a rise in airline travel due to the improving economy and low oil prices, have
resulted in long waits at major airports such as Chicago's O'Hare International. It is not
yet clear how much more effective airline security has become — but the lines are
obvious.
Part of the issue is that the government did not anticipate the steep increase in airline
travel, so the TSA is now rushing to get new screeners on the line. Part of the issue is that
airports have only so much room for screening lanes. Another factor may be that more
people are trying to overpack their carry-on bags to avoid checked-baggage fees, though
the airlines strongly dispute this.
There is one step the TSA could take that would not require remodeling airports or
rushing to hire: Enroll more people in the PreCheck program. PreCheck is supposed to be
a win-win for travelers and the TSA. Passengers who pass a background check are
eligible to use expedited screening lanes. This allows the TSA to focus on travelers who
are higher risk, saving time for everyone involved. TSA wants to enroll 25 million people
in PreCheck.
It has not gotten anywhere close to that, and one big reason is sticker shock: Passengers
must pay $85 every five years to process their background checks. Since the beginning,
this price tag has been PreCheck's fatal flaw. Upcoming reforms might bring the price to a
