Delay causes

Why American runs late on this route

Late-arriving aircraft accounts for 44% of the 21,000 delay minutes carriers reported here, and the remaining four split what is left.

  • Late-arriving aircraft
    44%
  • Carrier
    41%
  • Extreme weather
    8%
  • National Airspace System
    7%
  • Security
    0%

44% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 21,000 reported delay minutes here, that single category outweighs weather by 5 to one. The split is drawn from 21,416 reported delay minutes.

The largest share of delay minutes, 41%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 8,688 of the 21,000 delay minutes reported here.

Cancellations sit at 2.41% against a national 1.89%, which is ordinary. Diversions add another 0.29%.

Connections and stage length

What a delay here costs

9.8% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.

The 592 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.

The return leg is a different operation and performs like one: it runs 76.7% on time across 1,037 flights, 8 points above this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 8 points of difference.

One caution: this is a thin sample. 1,037 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.

What to do with this

Booking American on DFW to COS

Put together: treat all of this as provisional. 1,037 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 68.3% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 1,009 completed flights over 12 months sit behind that.
