Historical statistics for July 2025 to June 2026, not live status. For today’s DL 2045, check with Delta Air Lines.

DL 2045 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 11 points better than the national rate of 77.6%. When something does go wrong the average delay runs about an hour. That rests on 307 flights, with a median arrival 7 minutes early.

Set against the rest of the country, DL 2045's record is 11 points better than the US average of 77.6%. That gap is worth roughly 106 fewer late arrivals for every thousand flights.

These figures cover 307 flights between July 2025 and June 2026. The median arrival is 7 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 2045 flies

DL 2045 flies TPA to SLC without a single fixed slot. Its most common scheduled departure was 07:15, used on 148 of 307 flights, with 07:00 (120 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 07:15 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 2045 runs level with that at 88.2%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Against the route

DL 2045 next to TPA to SLC

Every carrier on TPA to SLC combined arrived on time 87.5% of the time across 368 flights, so DL 2045 is about level with it. Across its whole network Delta Air Lines managed 81.6%, which this flight beats by 7 points.

Across the year

DL 2045 quarter by quarter

DL 2045 did not run the same all year. Its best quarter was Apr–Jun 2026 at 94.3% on time and its weakest Jul–Sep 2025 at 83.7%, a swing of 11 points on roughly 77 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.

Jul–Sep 202592 flights83.7%
Oct–Dec 202590 flights91.0%
Jan–Mar 202690 flights87.8%
Apr–Jun 202635 flights94.3%

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

By weekday, DL 2045 ranged from 82.2% on Tuesday to 93.2% on Thursday. With about 44 flights behind each day, a spread of 11 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 2045 runs late

One category carries most of the weight here. Carrier accounts for 46% of the 2,151 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
46%
Late-arriving aircraft
39%
National Airspace System
15%

39% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 2,151 reported delay minutes here, that single category outweighs weather by 39 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 2,151 delay minutes reported on DL 2045.

Cancellations are rare at 0.33%, 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 2.6% 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 307 flights under DL 2045 in the data flew TPA to SLC. 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. 307 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 2045

For a booking, DL 2045 has one of the better records a US domestic flight can show: 88.2% on time and 0.33% cancelled. That is a base rate, not a promise about any single day.
