Ground delays on rise at U.S. airports
NEW YORK — On a recent morning, Delta Air Lines Flight 435 pushed back early from the gate at New York’s John F. Kennedy International Airport. Passengers watched the safety video and settled in for their trip.
Then they waited. And waited.
Still within sight of the gate, their jet sat motionless due to airport congestion. It wasn’t until 30 minutes after passengers buckled in that they were finally in the sky.
It’s a scene playing out across the country. According to an Associated Press analysis, airplanes spent 23 minutes and 32 seconds, on average, taxiing between gates and runways during the first nine months of the year. That’s the longest it has been since the Bureau of Transportation Statistics started tracking taxi times in 1995 and a 50-second increase over last year’s average.
For passengers, the increasing delays add to the frustrations of travel. A plane might land early but then sit waiting for a gate to open. Flights are still arriving “on time” but only because airlines have increased scheduled flying times to account for the added taxi times. The Delta flight made it to the gate in San Francisco 10 minutes ahead of schedule despite the takeoff delays.
The creep in taxi times is attributed to a series of changes: massive runway construction projects at some of the nation’s busiest airports; schedule changes that increase the number of flights at peak hours; and new, distant runways that relieve congestion but require more time to reach.
The problems on the ground are costing airlines dearly.
“Two, 3, 4, 5 minutes in a fleet of 500 planes a day is significant amounts of money,” says aviation consultant Mike Boyd.
That translates into hundreds
Flights are still arriving “on time,” but only because airlines have increased scheduled flying times to account for the added taxi times.
of millions of dollars extra in operating costs so far this year, according to AP calculations factoring in average operating costs including pilot and flight attendant salaries.
Airlines say the longer taxi times are baked into schedules, so planes generally still arrive on time. So far this year, 79 percent of flights have been at the gate within 15 minutes of their scheduled time, the best performance since 2012.
Passengers might be spending more time on planes, but airlines are better managing their expectations by increasing scheduled times. That masks some of the problems, such as taxi delays.
For instance, 10 years ago, the average scheduled time from gate to gate between Chicago and San Francisco was 4 hours and 32 minutes. Today, flights are scheduled for an extra 11 minutes, according to PlaneStats.com.
All it takes are a few problems at some of the country’s busiest airports to drive up the national taxi time average.
The top offender in the past year was Chicago’s O’Hare International Airport. Of all the additional taxi-time minutes in the nation, 1 of out of 5 extra minutes can be traced to delays at O’Hare.
Planes in Chicago this year spent an average of 1 minute and 18 seconds extra navigating the taxiways. And taxi times are up 3 minutes and 24 seconds from five years ago, a 20 percent increase.
Most of the problems at O’Hare stem from a construction project that is reconfiguring taxiways and runways.
Delays have also been climbing at the two main airports in Dallas, but for different reasons.
At Dallas Love Field, taxi times are up 2 minutes, or 13 percent, so far this year. That’s the highest percent gain of any major airport.
Home to Southwest Airlines, Love Field saw the number of scheduled flights during the first nine months of this year spike 41 percent, to 47,438, after the repeal of a federal law restricting most long-distance flights from that airport.
Terry L. Mitchell, the airport’s assistant director for operations, says the increase in flights, construction projects and the use of a further runway to reduce noise concerns of neighbors all led to the run up in taxi times.
At Dallas-Fort Worth International Airport, taxi times climbed 21⁄ minutes, or 11.7 percent. In this case, the increase was due to new scheduling procedures by American Airlines, which carries 82 percent of the passengers at the airport.
“When they try to cram as many flights as possible into their hubbing complexes,” says airline consultant Paul Sterbenz, “they create logjams.”
