These figures cover 363 flights between September 2025 and August 2026. The median arrival is 8 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.

Across the year
DL 2077 quarter by quarter
DL 2077 did not run the same all year. Its best quarter was Jul–Sep 2025 at 100.0% on time and its weakest Jul–Sep 2026 at 79.0%, a swing of 21 points on roughly 73 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.

By weekday, DL 2077 did best on Tuesday at 94.2% on time and worst on Wednesday at 78.8%. Each day rests on about 52 flights, so a gap of 15 points is worth noticing but could still narrow in another year.

The worst days
Worst days for DL 2077
The latest arrival of the period was on 11 January 2026, 3 hours 27 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 |
|---|---|---|
| 11 January 2026 | 3 hours 27 minutes | Carrier |
| 29 May 2026 | 2 hours 50 minutes | Carrier |
| 12 January 2026 | 2 hours 48 minutes | Carrier |

Delay causes
Why DL 2077 runs late
Carrier accounts for 62% of the 2,058 delay minutes carriers reported here, and the remaining four split what is left.
- 62%Carrier
- 23%Late-arriving aircraft
- 15%National Airspace System
The largest share of delay minutes, 62%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,281 of the 2,058 delay minutes reported here. The split is drawn from 2,058 delay minutes reported on DL 2077.
Cancellations are rare at 0.28%, 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 2.5% 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 1,888 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 363 flights under DL 2077 in the data flew SLC to TPA. 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. 363 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 2077
For a booking, DL 2077 has one of the better records a US domestic flight can show: 86.7% on time and 0.28% cancelled. That is a base rate, not a promise about any single day.
