Historical statistics for July 2025 to June 2026, not live status. For today’s AA 1205, check with American Airlines.

AA 1205 earns a D+, which is as low as this site's scale goes for a reason. Only 57.2% of flights arrive inside the 15-minute window, 20 points worse than the national rate of 77.6%. Late arrivals average close to two hours. Treat any tight connection here as a coin flip. That rests on 329 flights, with a median arrival 8 minutes late.

The national on-time rate over the same period is 77.6%, so AA 1205 runs 20 points behind the country as a whole. Across a thousand flights that is about 204 extra late arrivals.

These figures cover 329 flights between July 2025 and June 2026. Beyond the headline rate, 21.1% 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 1205 flies

AA 1205 flies MCO to LAX without a single fixed slot. Its most common scheduled departure was 17:55, used on 46 of 329 flights, with 19:20 (40 flights) and 17:42 (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 17:55 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and AA 1205 runs 11 points worse at 57.2%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Against the route

AA 1205 next to MCO to LAX

Every carrier on MCO to LAX combined arrived on time 80.4% of the time across 3,489 flights, so AA 1205 is 23 points behind it. American flew 735 flights on the same city pair under all its flight numbers, including this one, and those ran 73.4% on time. Across its whole network American Airlines managed 74.4%, which this flight trails by 17 points.

Across the year

AA 1205 quarter by quarter

AA 1205 did not run the same all year. Its best quarter was Jan–Mar 2026 at 72.7% on time and its weakest Jul–Sep 2025 at 31.9%, a swing of 41 points on roughly 82 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 202577 flights62.3%

Scale runs 25% to 80%. Rows with fewer than 30 flights show a dash.

By weekday, AA 1205 did best on Tuesday at 70.0% on time and worst on Monday at 46.0%. Each day rests on about 47 flights, so a gap of 24 points is worth noticing but could still narrow in another year.

Delay causes

Why AA 1205 runs late

One category carries most of the weight here. Carrier accounts for 44% of the 17,000 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
    44%
  • Late-arriving aircraft
    37%
  • Extreme weather
    13%
  • National Airspace System
    7%
  • Security
    0%

Extreme weather accounts for 13% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.1 times the usual weather exposure. The split is drawn from 17,050 delay minutes reported on AA 1205.

Cancellations are rare at 0.61%, below the national 1.81% 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

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 21.1% 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.

At 2,218 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.

Every one of the 329 flights under AA 1205 in the data flew MCO to LAX. 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. 329 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 1205

For a booking, AA 1205 is a flight to put a long connection behind. 21.1% 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.
