The latest arrival of the period was on 7 December 2025, 22 hours 9 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 7 December 2025 | 22 hours 9 minutes | Carrier |
| 28 January 2026 | 17 hours 33 minutes | Carrier |
| 15 February 2026 | 16 hours 50 minutes | Late-arriving aircraft |

Delay causes
Why AA 1205 runs late
Carrier accounts for 45% of the 13,000 delay minutes carriers reported here, and the remaining four split what is left.
- 45%Carrier
- 40%Late-arriving aircraft
- 8%National Airspace System
- 7%Extreme weather
- 0%Security
40% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 13,000 reported delay minutes here, that single category outweighs weather by 6 to one. The split is drawn from 13,033 delay minutes reported on AA 1205.
Cancellations are rare at 0.64%, 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
16.7% 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.
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 313 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. 313 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. 16.7% 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.
