Delay causes
Why American runs late on this route
Late-arriving aircraft accounts for 45% of the 33,000 delay minutes carriers reported here, and the remaining four split what is left.
- 45%Late-arriving aircraft
- 36%Carrier
- 13%National Airspace System
- 6%Extreme weather
45% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 33,000 reported delay minutes here, that single category outweighs weather by 7 to one. The split is drawn from 32,690 reported delay minutes.
The largest share of delay minutes, 36%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 12,000 of the 33,000 delay minutes reported here.
Cancellations sit at 1.44% against a national 1.89%, which is ordinary. Diversions add another 0.24%.
Connections and stage length
What a delay here costs
11.9% 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 700 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.
The return leg is a different operation and performs like one: it runs 78.4% on time across 1,666 flights, 6 points above this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 6 points of difference.
The sample behind these figures is 1,662 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.
What to do with this
Booking American on MIA to RDU
Put together: the calendar is the biggest lever here, not the carrier or the hour. October runs 79.9% on time and July 56.6%, a swing of 23 points. If the dates move at all, move them out of July before you think about anything else. 1,634 completed flights over 12 months sit behind that.
