Historical statistics for July 2025 to June 2026, not live status. For today’s AA 2230, check with American Airlines.
AA 2230 sits in the middle of the pack with a C. About seven flights in ten arrive on time by the DOT's definition, 9 points worse than the national rate of 77.6%. The late ones land about an hour behind schedule. That rests on 362 flights, with a median arrival 2 minutes early.
The national on-time rate over the same period is 77.6%, so AA 2230 runs 9 points behind the country as a whole. Across a thousand flights that is about 89 extra late arrivals.

These figures cover 362 flights between July 2025 and June 2026. Beyond the headline rate, 10.4% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Schedule
When AA 2230 flies
AA 2230 flies MIA to IAH without a single fixed slot. Its most common scheduled departure was 22:10, used on 106 of 362 flights, with 21:50 (98 flights) and 22:40 (37 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 22:10 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and AA 2230 runs level with that at 68.7%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year
AA 2230 quarter by quarter
AA 2230 did not run the same all year. Its best quarter was Apr–Jun 2026 at 74.4% on time and its weakest Jan–Mar 2026 at 62.1%, a swing of 12 points on roughly 91 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

- Oct–Dec 202589 flights73.9%
- Jan–Mar 202690 flights62.1%

By weekday, AA 2230 did best on Wednesday at 80.4% on time and worst on Sunday at 51.0%. Each day rests on about 52 flights, so a gap of 29 points is worth noticing but could still narrow in another year.
Delay causes
Why AA 2230 runs late
One category carries most of the weight here. Carrier accounts for 46% of the 7,144 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 46%Carrier
- 37%Late-arriving aircraft
- 13%National Airspace System
- 4%Extreme weather
- 0%Security
37% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 7,144 reported delay minutes here, that single category outweighs weather by 10 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 7,144 delay minutes reported on AA 2230.
Cancellations sit at 1.66% against a national 1.81%, which is ordinary. Diversions add another 0.28%.
Connections and routes
What a delay on this flight costs
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 10.4% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
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.
