Delay causes
Why F9 4725 runs late
Late-arriving aircraft accounts for 83% of the 10,000 delay minutes carriers reported here, and the remaining four split what is left.
- 83%Late-arriving aircraft
- 13%Carrier
- 4%National Airspace System
83% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 10,000 reported delay minutes here, that single category outweighs weather by 83 to one. The split is drawn from 10,417 delay minutes reported on F9 4725.
Cancellations are rare at 0.36%, 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
15.6% 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.
The 1,188 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.
Every one of the 276 flights under F9 4725 in the data flew SJU 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. 276 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 F9 4725
For a booking, F9 4725 is a flight to put a long connection behind. 15.6% 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.
