Historical statistics for July 2025 to June 2026, not live status. For today’s DL 2075, check with Delta Air Lines.

DL 2075 lands a B, 3 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by roughly 45 minutes on average. That is a workable record, not a spotless one. That rests on 267 flights, with a median arrival 5 minutes early.

These figures cover 267 flights between July 2025 and June 2026. The median arrival is 5 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 2075 flies

DL 2075 flies SLC to PHL without a single fixed slot. Its most common scheduled departure was 23:38, used on 41 of 267 flights, with 23:30 (31 flights) and 23:59 (30 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

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

A 23:38 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and DL 2075 runs 10 points better at 80.9%. 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 2075 next to SLC to PHL

Every carrier on SLC to PHL combined arrived on time 84.7% of the time across 833 flights, so DL 2075 is 4 points behind it. Delta flew 613 flights on the same city pair under all its flight numbers, including this one, and those ran 82.9% on time. Across its whole network Delta Air Lines managed 81.6%, close to this flight's figure.

Across the year

DL 2075 quarter by quarter

DL 2075 did not run the same all year. Its best quarter was Apr–Jun 2026 at 90.5% on time and its weakest Oct–Dec 2025 at 66.0%, a swing of 25 points on roughly 67 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 202572 flights80.3%
Oct–Dec 202553 flights66.0%
Jan–Mar 202678 flights84.0%

Scale runs 60% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, DL 2075 did best on Monday at 83.7% on time and worst on Sunday at 71.7%. Each day rests on about 38 flights, so a gap of 12 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 2075 runs late

One category carries most of the weight here. Carrier accounts for 53% 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
53%
National Airspace System
34%
Late-arriving aircraft
13%

34% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 736 minutes out of 2,151, against a national NAS share of 21%. The split is drawn from 2,151 delay minutes reported on DL 2075.

Cancellations sit at 1.87% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 2.3% 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 1,927 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 267 flights under DL 2075 in the data flew SLC to PHL. 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. 267 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.
