Across the year
DL 1490 quarter by quarter
DL 1490 did not run the same all year. Its best quarter was Oct–Dec 2025 at 75.9% on time and its weakest Jul–Sep 2026 at 60.7%, a swing of 15 points on roughly 67 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

Share of 260 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 55 departures that left 15 minutes late or more, only 4 made it up before arrival. In the other direction, 22 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at BNA.
The worst days
Worst days for DL 1490
The latest arrival of the period was on 17 July 2026, 3 hours 16 minutes behind schedule; most of its delay minutes were filed as national airspace system delay. The five worst days are spread across July, April, May and December, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 17 July 2026 | 3 hours 16 minutes | National Airspace System |
| 19 July 2026 | 3 hours 2 minutes | Carrier |
| 28 April 2026 | 2 hours 50 minutes | National Airspace System |

Delay causes
Why DL 1490 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 3,896 reported delay minutes.
- 37%Carrier
- 35%National Airspace System
- 24%Late-arriving aircraft
- 4%Extreme weather
35% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 1,357 minutes out of 3,896, against a national NAS share of 21%. The split is drawn from 3,896 delay minutes reported on DL 1490.
Cancellations sit at 2.24% against a national 1.89%, which is ordinary. Diversions add another 0.75%.
Connections and routes
What a delay on this flight costs
9.2% 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 two other city pairs in the data, including BNA to ATL (80) and PIT to ATL (6), but none flew often enough under DL 1490 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ATL to BNA only.
One caution: this is a thin sample. 268 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
