Share of 320 completed flights by arrival against schedule.
16 of 80 late departures made up the time and arrived on time, 20% of them. In the other direction, 32 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 LAS.
The worst days
Worst days for DL 916
The latest arrival of the period was on 13 March 2026, 20 hours 5 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 13 March 2026 | 20 hours 5 minutes | Carrier |
| 9 July 2026 | 3 hours 14 minutes | Carrier |
| 24 September 2025 | 3 hours 5 minutes | Carrier |
| 7 April 2026 | 2 hours 53 minutes | Carrier |

Delay causes
Why DL 916 runs late
Carrier accounts for 59% of the 6,658 delay minutes carriers reported here, and the remaining four split what is left.
- 59%Carrier
- 25%National Airspace System
- 14%Late-arriving aircraft
- 1%Extreme weather
- 1%Security
The largest share of delay minutes, 59%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 3,928 of the 6,658 delay minutes reported here. The split is drawn from 6,658 delay minutes reported on DL 916.
Cancellations are rare at 0.62%, 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
10.3% 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.
At 1,749 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.
Every one of the 322 flights under DL 916 in the data flew DTW to LAS. 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. 322 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 916
