Share of 251 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 47 departures that left 15 minutes late or more, only 3 made it up before arrival. In the other direction, 19 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at ASE.

The latest arrival of the period was on 26 July 2026, 8 hours 1 minute behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The five worst days are spread across July, March, December, February and October, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 26 July 2026 | 8 hours 1 minute | Late-arriving aircraft |

Delay causes
Why OO 5814 runs late
Carrier accounts for 45% of the 4,828 delay minutes carriers reported here, and the remaining four split what is left.
- 45%Carrier
- 35%National Airspace System
- 18%Late-arriving aircraft
- 3%Extreme weather
35% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 1,686 minutes out of 4,828, against a national NAS share of 21%. The split is drawn from 4,828 delay minutes reported on OO 5814.
Cancellations are rare at 0.76%, 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 routes
What a delay on this flight costs
12.7% 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 913 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 same number turns up on two other city pairs in the data, including CRW to ORD (2) and ORD to DAY (1), but none flew often enough under OO 5814 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to IAH to ASE only.
One caution: this is a thin sample. 263 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 OO 5814
For a booking, OO 5814 is a flight to put a long connection behind. 12.7% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
