Delay causes
Why AA 2230 runs late
Carrier accounts for 50% of the 7,802 delay minutes carriers reported here, and the remaining four split what is left.
- 50%Carrier
- 36%Late-arriving aircraft
- 10%National Airspace System
- 5%Extreme weather
- 0%Security
36% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 7,802 reported delay minutes here, that single category outweighs weather by 8 to one. The split is drawn from 7,802 delay minutes reported on AA 2230.
Cancellations sit at 1.38% against a national 1.89%, which is ordinary. Diversions add another 0.28%.
Connections and routes
What a delay on this flight costs
10.7% 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 964 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.
Every one of the 362 flights under AA 2230 in the data flew MIA to IAH. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 362 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.
