Delta Air Lines Meltdown — Hundreds Of Flights Canceled While Rivals Run Fine Amid Internal “Crew Restrictions”

Delta Air Lines has cancelled hundreds of flights over the past two days. A number of readers have asked me what on earth is going on, and I’ve been a bit perplexed.

• Delta has cancelled nearly as many flights as Spirit Airlines today, and Spirit Airlines ceased operations entirely. They’ve also delayed 1,000 flights over the past two days.

• Weather is basically good, and they do not appear to be having technology issues.

• Everything I’ve heard is crew – pilots – but the stories about pilots calling out sick en masse do not check out, and it’s not clear what would have triggered that in any case. (No clear motive, always ask ‘why now?’)

The airline is no longer nearly as reliable as it used to be. And they do a poor job recovering from operational meltdowns now. Their pilot contract gets a lot of the blame and executives talked about working with the pilot union to fix this during their first quarter earnings call.

But this is only a problem when the operation itself becomes a problem. Nothing here appears to have triggered that in the first place! Aviation watchdog JonNYC is on the case.

today so far, Delta at 6% cancellation rate, AA and UA effectively 0%.

not overly relevant, but,DOT numbers are out for January.

DL canceled 4.5% of flights, ranking number 6 of the large US carriers.

Delta is cancelling flights while American and United and Southwest are not cancelling flights. Delta is at 209 cancels for the day so far (Spirit shows 277). Southwest is at 21 (0%), United 15 (0%), American 4 (0%). Here’s what JonNYC has been able to confirm:

1. This is a Delta-specific issue
   
2. They are not handling it well (he notes there’s been a lot of turnover in scheduling at Delta).
   
3. As I expected, there’s no sick out
   
4. So it seems like the trigger could have been a delayed snowball effect from weather at the beginning of this past week. My guess here is that when scheduling fills trips, they break future pilot sequences, and then they have to go start filling those.

As far as the current situation

This definitely all seems to be directly related to DL's systems and staffing (including the fact that there are a far amount of new/inexperienced folks working in [the relevant department(s) that deal with IRROPS recovery.)

The one small caveat…

The entire airline industry is in flux in an interesting way. Delta clearly isn’t as premium as it used to be, they’re even cutting drink service on short flgihts. And isn’t as reliable. They used to be operationally head and shoulders above others, but now there’s room for competition. And Delta’s President, who really ran the airline, has retired. They lost their operations guru during the pandemic (he’s now CEO of Hertz, and Hertz has stopped arresting customers!).

No airline has improved as much as United over the past decade, but they certainly aren’t meaningfully ahead of others – except for their mobile app and with Starlink wifi installs. It seems, then, there’s a real opening at the top right as there’s a real shakeup in the industry.
