Across the year
DL 2855 quarter by quarter

The latest arrival of the period was on 28 February 2026, 15 hours 23 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 |
|---|---|---|
| 28 February 2026 | 15 hours 23 minutes | Carrier |
| 13 April 2026 | 15 hours 22 minutes | Carrier |

Delay causes
Why DL 2855 runs late
Carrier accounts for 76% of the 5,084 delay minutes carriers reported here, and the remaining four split what is left.
- 76%Carrier
- 13%Late-arriving aircraft
- 9%National Airspace System
- 2%Extreme weather
The largest share of delay minutes, 76%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 3,846 of the 5,084 delay minutes reported here. The split is drawn from 5,084 delay minutes reported on DL 2855.
Cancellations are rare at 0.38%, 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
8.0% 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 1,565 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 three other city pairs in the data, including TVC to ATL (3), ATL to TVC (3) and SLC to BUR (1), but none flew often enough under DL 2855 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SLC to CLE only.
One caution: this is a thin sample. 264 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 2855
