September’s On-Time Rankings Are Out—Delta Dominates While American Slips Further Behind

Delta Air Lines was once again the best on-time carrier in the U.S. and Canada in September, according to data from aviation analytics company Cirium.

They were followed by Alaska, which consistently does well on this metric. Every major U.S. airline cancelled fewer than 1% of its flights for the month, though JetBlue was the least on-time carrier (just slightly worse than Frontier) and second-worst for cancelled flights (American was most-likely to cancel).

Overall, United and Spirit performed well. American, Frontier, and JetBlue perofrmed poorly. Wihle Southwest’s on-time performance slipped to be worse than American’s, they tied for U.S. industry-leading in completing and not cancelling their flights.

Given its scale, Delta’s relative performance is even more impressive – and the distance American Airlines is behind becomes even clearer.

Operational performance isn’t just on-time performance, of course. American generally ends up last for mishandled bags and lost wheelchairs, and also for involuntarily denying boarding to passengers due to oversold flights.

Among global airlines, Delta was third. The most on-time was Delta’s vassal to the south, Aeromexico. Looking at performance over the past three months, Delta overcame a poor period to consistently hit high marks. They were tops in August also. July was brutal across-the-board, while August was a bit better and September pretty good for most carriers.

There’s a relationship between most on-time airline and most on-time airport. Aeromexico was the most on-time airline, and Mexico City number two among airports. Delta was tops in the U.S. and Canada, and its Salt Lake City and Detroit hubs were both in the top 6 among the largest world airports for on-time performance. Honolulu, which often has the least weather to deal with, was in the number one slot.

Ultimately, September’s airline punctuality rankings show that Delta is in the lead and United hasn’t actually caught up – but also that American continues to slip. And JetBlue and Frontier, of course, can’t seem to get their acts together. At least at Frontier ‘paying with your time instead of money’ is baked into the value proposition.

  1. @Tim Dunn — “Delta Dominates” great start to the week, eh? Keep Climbing! 100 more years!

  2. it is worth noting that DL’s ontime percentage is further above AS than AS is to UA, AA and WN.

    The fall is always a good time to make up space in the annual on-time race because of good weather

    The difference is that DL adds just a little more block time to reduce the percentage of flights that are delayed in bad weather but those extra minutes in good weather -like the fall – mean that a fairly high percentage of DL flights gets in early. Other airlines just are not willing to invest that much extra in being on-time.

    and poor B6 just can’t get out of the cellar.

  3. None of this really makes sense. AA completed we do we not see the REASON WHY ?

    Also is not the Airport issue of pushback and take off vs the airline.

    Can not tell you how many flights i been on where the doors are shut and we just sit there. Waitinig for a push back, for the tower to clear a runway for take off, , sitting in line “We are #12 for take off”

    Landing at an airport and waiting to get to a gate because there are non free (thanks FAA for sgiving them all the DL). Waiting to get to a gate because rescue and fire was blocking the gate as a man was having a heart attack on another arriving flight. Waiting for snow to be cleared sot he plane could hook up

  4. Anecdotal of course but I flew Delta, United, and AA last week and only the AA flight got delayed. These figures absolutely make a difference when choosing a carrier when there’s a competing route.

    @1990 — Woohoo! @Tim Dunn has spoken (great points), now for @Matt to make an appearance as well!

  5. @Tim Dunn — Speaking of weather, oof, not great in the Mid-Atlantic these 48 hours. Apparently, the post-Sandy resiliency efforts in NY/NJ are paying off, for now (no flooded tunnels, yet.)

    @tomri — Whining about a delay caused by a fellow passenger’s heart-attack… bad karma, dude.

  6. Personally I always “bake in” departure and arrival delays at MIA since the airport runs on Cuban time, habitually late on arriving and leaving.

  7. In September AA got hammered at DFW due to a near week of intense storms. These stats are easily impacted when a mega hub has multiple days of bad weather. Let’s see what happens to UA this month with all the problems at EWR.

  8. @George Nathan Romey — Not to nitpick or ‘defend New Jersey,’ but other than the shutdown, which is affecting all airports, and the issues from earlier this year with the runway construction (now complete) and staffing shortages at the FAA (not great, but not terrible compared to other months), what are “all the problems at EWR” that you’re referring? I mean, this Nor’easter isn’t good, but it’s like a 1-2 day event, not a ‘week of intense storms.’
