Delay causes
Why DL 1450 runs late
Late-arriving aircraft accounts for 45% of the 5,360 delay minutes carriers reported here, and the remaining four split what is left.
- 45%Late-arriving aircraft
- 41%Carrier
- 11%National Airspace System
- 3%Extreme weather
- 1%Security
45% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 5,360 reported delay minutes here, that single category outweighs weather by 15 to one. The split is drawn from 5,360 delay minutes reported on DL 1450.
Cancellations sit at 1.44% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
9.6% 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 same number turns up on one other city pair in the data, including ATL to BHM (16), but none flew often enough under DL 1450 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ATL to MSY only.
One caution: this is a thin sample. 348 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

For a booking, DL 1450 is one of the weaker ways to fly ATL to MSY: 6 points below the route as a whole. If the schedule allows, compare it with the other departures listed on the route page before settling on this one.
