Fliers gripe that getting through airport security lines can be too slow. Now, it may be fliers who are slow to sign up for a program to speed them through the lines. The Transportation Security Administration is aggressively trying to encourage more people to sign up for TSA Precheck, reports The Wall Street Journal (April 17, 2014). 

Precheck, launched in 2011, is much-loved among travelers because they don’t have to take off their shoes and jackets, don’t have to pull liquids and laptops out of baggage, and can walk through metal detectors without a full-body scan. By doing background checks on Precheck enrollees and scanning law-enforcement databases, TSA offers what is essentially pre-9/11 screening to “trusted travelers.”

TSA wants lots more people enrolled in Precheck to make better use of its designated security lanes, which currently number 590 at 118 U.S. airports. “It’s one of the last great bargains the U.S. government is offering,” TSA Administrator John Pistole has joked. To entice travelers into Precheck and test TSA’s ability to handle more people, the agency has been selecting regular passengers to go through Precheck security lanes and get it printed on their boarding passes. Selection is based on criteria like passengers’ travel history and the route being flown. TSA officers trained in behavior detection also can move passengers they deem low risk from regular queues into Precheck lanes.

Pistole said he has heard the complaints about Precheck lanes getting clogged, and TSA has already decided to stop moving travelers 75 years of age and older into Precheck service, unless they are enrolled, because they sometimes can take 10 minutes to move through. “It used to be great, but recently the Precheck lines have been the slowest of all the lines,” said Northeastern University OM Professor Fred Van Bennekom, who has timed TSA lines. “Sometimes there’s almost no one in regular lines and we’re all backed up at Precheck.”

“The crew of Delta Air Lines Flight 55 last Thursday couldn’t legally fly from Lagos, Nigeria, to Atlanta unless they waited a day due to new limits on how much pilots can fly in a rolling 28-day period,” writes The Wall Street Journal (April 3, 2014). The trip would have to be canceled. Instead, Delta headquarters told the captain to fly to San Juan, which they could reach within their duty limits. There, two new pilots would be waiting to take theBoeing 767 on to Atlanta. The plane arrived in San Juan at 2:44 a.m., quickly took on fuel and pilots, and landed in Atlanta only 40 minutes late.

The episode, unorthodox in the airline industry, illustrates the fanaticism Delta now has for avoiding cancellations. Last year, Delta canceled just 0.3% of its flights. That was twice as good as the next-best airlines, Southwest and Alaska, and five times better than the industry average of 1.7%.

As it cut cancellations with a more-reliable operation, overall on-time arrivals improved and Delta has fewer delays. Managers in Delta operations center (featured in our Global Company Profile  in Chapter 15) move planes, crews and parts around hourly trying to avoid canceling flights. How well an airline maintains its fleet and how smartly it stashes spare parts and planes at airports affect whether a flight goes or not. Delta’s new analytical software and instruments that can help monitor the health of airplanes and predict which parts will soon fail. Empty planes are ferried to replace crippled jets rather than waiting for overnight repairs. Typically the airline has about 20 spare airplanes of different sizes each day. About half are stationed in Atlanta and the rest spread around other domestic hubs and two in Tokyo.
