Across the year
AA 300 quarter by quarter

| 24 February 2026 | 13 hours 48 minutes | Carrier |
| 4 April 2026 | 11 hours 37 minutes | Carrier |

Delay causes
Why AA 300 runs late
Late-arriving aircraft accounts for 48% of the 9,932 delay minutes carriers reported here, and the remaining four split what is left.
- 48%Late-arriving aircraft
- 36%Carrier
- 12%National Airspace System
- 4%Extreme weather
- 0%Security
48% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 9,932 reported delay minutes here, that single category outweighs weather by 12 to one. The split is drawn from 9,932 delay minutes reported on AA 300.
Cancellations run at 3.32%, against 1.89% nationally. That is about one flight in 30 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and routes
What a delay on this flight costs
16.1% 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 2,475 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 361 flights under AA 300 in the data flew JFK 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. 361 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 300
For a booking, the cancellation rate is the figure to plan around on AA 300: 3.32% of its 361 scheduled flights did not operate. A late arrival costs an hour and a half, but a cancellation costs the day, so leave a later option open.
