These figures cover 343 flights between July 2025 and June 2026. Beyond the headline rate, 14.1% 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 1879 flies

AA 1879 flies CLT to MCO without a single fixed slot. Its most common scheduled departure was 20:15, used on 80 of 343 flights, with 22:25 (71 flights) and 22:28 (71 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 20:15 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and AA 1879 runs 9 points worse at 61.4%. 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 1879 quarter by quarter

AA 1879 did not run the same all year. Its best quarter was Oct–Dec 2025 at 67.9% on time and its weakest Jul–Sep 2025 at 50.0%, a swing of 18 points on roughly 86 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.

By weekday, AA 1879 did best on Wednesday at 80.9% on time and worst on Sunday at 34.7%. Each day rests on about 49 flights, so a gap of 46 points is worth noticing but could still narrow in another year.

Delay causes

Why AA 1879 runs late

One category carries most of the weight here. Carrier accounts for 43% of the 11,000 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.

Carrier
43%
Late-arriving aircraft
42%
National Airspace System
11%
Extreme weather
3%

42% 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 11,000 reported delay minutes here, that single category outweighs weather by 13 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 10,977 delay minutes reported on AA 1879.

Cancellations sit at 2.04% against a national 1.81%, which is ordinary. Diversions add another 0.58%.

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. 14.1% 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.

Every one of the 343 flights under AA 1879 in the data flew CLT to MCO. 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. 343 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 AA 1879

For a booking, AA 1879 is a flight to put a long connection behind. 14.1% 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.
