Carrier by carrier

Southwest against every carrier on DEN to ICT

Southwest flew 559 of the 2,231 flights on DEN to ICT, about 25% of it. Its 61.5% on time is 16 points worse than the route as a whole, which runs 77.7%. Ranked by on-time rate it is last of three carriers on the route, where the range runs from SkyWest at 85.3% to Southwest at 61.5%.

The choice of carrier is not cosmetic here. SkyWest Airlines arrives on time 85.3% of the time; United Airlines manages 75.6%. Sample sizes sit next to every figure, because a two-point gap across 372 flights means less than a ten-point one.

The 8pm–5am window is where this operation falls apart: 49.3% on time, against 85.5% for the 8am–11am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 5pm–8pm window is the busiest, with 181 flights scheduled in it.

Delay causes

Why Southwest runs late on this route

Late-arriving aircraft accounts for 55% of the 13,000 delay minutes carriers reported here, and the remaining four split what is left.

  • Late-arriving aircraft
    55%
  • Carrier
    34%
  • National Airspace System
    8%
  • Extreme weather
    3%
  • Security
    0%

55% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 13,000 reported delay minutes here, that single category outweighs weather by 20 to one. The split is drawn from 12,864 reported delay minutes.

The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 85.5% on time here.

Cancellations are rare at 0.72%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

Connections and stage length

What a delay here costs

14.1% 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.

At 420 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 8am–11am window matters as much as it does.

The return leg is a different operation and performs like one: it runs 81.6% on time across 559 flights, 20 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 20 points of difference.

One caution: this is a thin sample. 559 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 Southwest on DEN to ICT

Put together: treat all of this as provisional. 559 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 61.5% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 553 completed flights over 12 months sit behind that.
