Historical statistics for July 2025 to June 2026, not live status. For today’s DL 2077, check with Delta Air Lines.

DL 2077 earns an A+. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 10 points better than the national rate of 77.6%. When something does go wrong the average delay runs roughly 55 minutes. That rests on 363 flights, with a median arrival 9 minutes early.

Set against the rest of the country, DL 2077's record is 10 points better than the US average of 77.6%. That gap is worth roughly 100 fewer late arrivals for every thousand flights.

These figures cover 363 flights between July 2025 and June 2026. The median arrival is 9 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.

Schedule

When DL 2077 flies

DL 2077 flies SLC to TPA without a single fixed slot. Its most common scheduled departure was 23:55, used on 61 of 363 flights, with 23:46 (47 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 23:55 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and DL 2077 runs 17 points better at 87.6%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Against the route

DL 2077 next to SLC to TPA

Every carrier on SLC to TPA combined arrived on time 86.4% of the time across 368 flights, so DL 2077 is about level with it. Across its whole network Delta Air Lines managed 81.6%, which this flight beats by 6 points.

Across the year

DL 2077 quarter by quarter

Quarter by quarter DL 2077 held fairly steady: 89.1% in Jul–Sep 2025, 93.3% in Oct–Dec 2025, 84.4% in Jan–Mar 2026 and 83.5% in Apr–Jun 2026. A spread of 10 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202592 flights89.1%
Oct–Dec 202590 flights93.3%
Jan–Mar 202690 flights84.4%

Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, DL 2077 ranged from 84.3% on Friday to 96.2% on Tuesday. With about 52 flights behind each day, a spread of 12 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 2077 runs late

One category carries most of the weight here. Carrier accounts for 66% of the 2,383 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

Carrier
66%
Late-arriving aircraft
19%
National Airspace System
10%
Extreme weather
5%

The largest share of delay minutes, 66%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 1,564 of the 2,383 delay minutes reported here. The split is drawn from 2,383 delay minutes reported on DL 2077.

Cancellations are rare at 0.28%, below the national 1.81% 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 3.6% land an hour or more behind schedule, against 8.1% 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: 87.6% on time and 0.28% cancelled. That is a base rate, not a promise about any single day.
