These figures cover 356 flights between September 2025 and August 2026. The median arrival is 6 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.

A 07:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 2915 runs 9 points worse at 80.4%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year
DL 2915 quarter by quarter

Share of 352 completed flights by arrival against schedule.
11 of 59 late departures made up the time and arrived on time, 19% of them. In the other direction, 21 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 2915
The latest arrival of the period was on 30 October 2025, 4 hours 44 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on five of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 30 October 2025 | 4 hours 44 minutes | Carrier |
| 1 September 2025 | 3 hours 45 minutes | Carrier |
| 3 November 2025 | 3 hours 22 minutes | Carrier |

Delay causes
Why DL 2915 runs late
Carrier accounts for 58% of the 3,855 delay minutes carriers reported here, and the remaining four split what is left.
- 58%Carrier
- 22%Late-arriving aircraft
- 18%National Airspace System
- 2%Extreme weather
- 1%Security
The largest share of delay minutes, 58%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,217 of the 3,855 delay minutes reported here. The split is drawn from 3,855 delay minutes reported on DL 2915.
Cancellations are rare at 0.84%, 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
Badly late arrivals are rare here: only 4.8% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
At 1,678 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 356 flights under DL 2915 in the data flew CVG 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. 356 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 2915
