Security Lines: How to Speed Through

More travelers may mean longer lines at airport security and customs and immigration checkpoints. The Transportation Security Administration said this week that it expects to screen 2.6 million passengers on Friday, which it predicts to be the busiest travel day of Memorial Day weekend. That’s more even than 2019, when 2.4 million travelers were screened.

In advance of the holiday, the agency said that it was taking measures to speed travelers through. Teenagers under 18 can now accompany parents or guardians who are enrolled in T.S.A. PreCheck through security when traveling on the same reservation; children 12 and under had previously been able to accompany their parents.

And the agency said its staffing levels were up because all its employees were getting a raise as of July 1. The promise of higher wages had made making recruiting efforts easier.

The agency says technology will also speed things up.

Now, at 16 U.S. airports, passengers no longer need to show their boarding passes to go through security, although they may need to show them at the gate. At these airports, travelers can swipe their identifying documents — a driver’s license or a passport, for example — in front of the security officer, and facial recognition technology will check for a match. Then an officer will check the ID before sending the passenger through.

New scanners that expedite security by allowing liquids and laptops to stay inside the bags are on the way as well, but “it’s going to be years before this becomes a reality,” said the T.S.A. press secretary, R. Carter Langston.

To speed your way, it can help to sign up for one of the programs offered by the government or Clear, a private company. But time is running out.

T.S.A.’s PreCheck program permits travelers departing from U.S. airports to go through screening without removing their shoes, belts or laptops, which can speed the process so significantly that in April, the T.S.A. said, 89 percent of PreCheck passengers waited less than five minutes in line. Many credit cards reimburse for PreCheck enrollment, which normally costs $78. And once approved, PreCheck lasts for five years. Although approval can be quick, it could take up to 60 days.

For $22 more, passengers can apply for Global Entry, which includes PreCheck, is also valid for five years and expedites entry into the U.S. from international destinations. Many credit cards also reimburse for Global Entry. The big drawback is that approval requires an…
