Another US DOT dataset has been updated, covering on-time performance through March 2025.
There is a lot to unpack here. The line curves on page one are interactive. Click on 2025, and the charts open to months. Click a month, and it expands to display the days of that month. You can also select an airline to view its performance throughout the year.
- The top 15 destinations table provides clear clues right away. There is no green as the industry’s performance is less “on-time. Remember, the FAA gives a 15-minute grace period. YTD, the industry is already over that.
- The airports are listed in descending order of delays. Newark does not fall into the top 15, in case you’re wondering. ATL, despite being the busiest airport in the world, does surprisingly well.
- Notice schedule padding time is creeping up, too.
- The reasons for delays reported show that the industry continues to make “own goals.”
