These figures cover 340 flights between September 2025 and August 2026. The median arrival is 7 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 16 October 2025 | 5 hours 41 minutes | Carrier |
| 14 October 2025 | 5 hours 25 minutes | Carrier |
| 26 April 2026 | 5 hours 2 minutes | Carrier |

Delay causes
Why DL 446 runs late
Carrier accounts for 53% of the 4,183 delay minutes carriers reported here, and the remaining four split what is left.
- 53%Carrier
- 34%Late-arriving aircraft
- 13%National Airspace System
34% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,183 reported delay minutes here, that single category outweighs weather by 34 to one. The split is drawn from 4,183 delay minutes reported on DL 446.
Cancellations sit at 1.18% against a national 1.89%, which is ordinary. Diversions add another 0.59%.
Connections and routes
What a delay on this flight costs
5.1% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last an hour and a half, which a normal layover absorbs.
At 1,947 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.
The same number turns up on one other city pair in the data, including MIA to BOS (16), but none flew often enough under DL 446 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LAX to ATL only.
One caution: this is a thin sample. 340 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 DL 446
