Delta Air Lines was named the World’s Most On-Time Airline among mainline carriers by the aviation data and analytics company FlightGlobal, incorporating FlightStats, and is the first U.S. airline to earn the industry-leading distinction in the nine years FlightGlobal’s FlightStats has presented its OPS Awards, according to a release by the company Tuesday.

In 2017, Delta’s mainline operation saw 85.94 percent of flights arrive within 14 minutes of the scheduled arrival time, the industry’s widely used definition of on-time, according to FlightStats.

“We are extremely proud of what Delta employees have been able to accomplish in service to our customers to drive a safe and reliable global operation,” said Gil West, Delta’s Executive Senior Vice President and Chief Operating Officer. “The results reported by FlightStats are humbling and yet another proof point that Delta employees worldwide are redefining operational excellence. Hats off to all Delta employees who come to work every day looking for ways to make meaningful improvements to the airline and continue to differentiate ourselves from our competitors.”

Delta was also recognized as North America’s most on-time major carrier—a title that takes into account the Delta Connection regional operation.

FlightStats reports that Delta, together with its regional partners, saw 84.06 percent of flights arrive on time in 2017, based on FlightStats’ analysis of flight status and arrival data pulled from over 600 global sources and data feeds.

Delta flies more than 180 million customers annually on approximately 5,000 daily mainline and Delta Connection flights. The airline achieved its strong operational performance in 2017 despite a string of hurricanes in the U.S. and Caribbean, and a snow storm at Delta’s largest hub in Atlanta in December. Still Delta recorded several company bests, including a record 242 days in 2017 without a mainline flight cancellation and 90 days in which mainline and Delta Connection were cancel-free.
