On Sept. 2, roughly 5,000 Delta and Delta Connection flights crisscrossed the globe without a single cancellation. The next day it happened again. And then again. For more than eight days, the operation hummed along sans cancel, beating the previous record by about 12 hours.
During that time, 38,531 flights flew to 321 destinations in 56 countries. The record-breaking streak, which ended Saturday, brings the number of cancel-free days across the combined Delta and Delta Connection operation to 46.1
“It’s astounding what Delta people have accomplished so far this year to be the most reliable airline in the industry for our customers,” said Dave Holtz, Delta’s Senior Vice President – Operations and Customer Center. “It was just a few short years ago that a completely cancel-free day was almost unheard of in the industry, we’re already at 46 with three months still to go.”
By comparison, by this time last year, Delta had notched just six so-called “brand days” with 11 for the full year 2015.2
Similarly, Delta’s mainline operation—which excludes regional flights—is just one cancel-free day away from matching last year’s 161 days without a cancellation. Holtz says the airline could reach 200 mainline cancel-free days by year’s end.
Year-to-date through July, the latest publically available Department of Transportation comparative data for all airlines, Delta’s domestic mainline operation saw 147 cancel-free days, six more than American Airlines, Alaska Airlines, JetBlue Airways, United Airlines and Southwest Airlines combined.3
