Historical statistics for July 2025 to June 2026, not live status. For today’s DL 1202, check with Delta Air Lines.

DL 1202 earns a B+. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 7 points better than the national rate of 77.6%. When something does go wrong the average delay runs about an hour. That rests on 364 flights, with a median arrival 7 minutes early.

Set against the rest of the country, DL 1202's record is 7 points better than the US average of 77.6%. That gap is worth roughly 68 fewer late arrivals for every thousand flights.

Key figures

These figures cover 364 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 1202 flies

DL 1202 flies SLC to SAN without a single fixed slot. Its most common scheduled departure was 22:45, used on 116 of 364 flights, with 22:50 (67 flights) and 21:45 (51 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

  • Departs 22:5067 flights18.4%
  • Departs 21:4551 flights14.0%

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 22:45 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and DL 1202 runs 14 points better at 84.4%. 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 1202 next to SLC to SAN

Every carrier on SLC to SAN combined arrived on time 83.2% of the time across 2,958 flights, so DL 1202 is about level with it. Delta flew 1,731 flights on the same city pair under all its flight numbers, including this one, and those ran 83.8% on time. Across its whole network Delta Air Lines managed 81.6%, which this flight beats by 3 points.

Across the year

DL 1202 quarter by quarter

Quarter by quarter DL 1202 held fairly steady: 89.0% in Jul–Sep 2025, 79.8% in Oct–Dec 2025, 82.0% in Jan–Mar 2026 and 86.8% in Apr–Jun 2026. A spread of 9 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

  • Oct–Dec 202591 flights79.8%
  • Jan–Mar 202690 flights82.0%

Scale runs 70% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, DL 1202 did best on Tuesday at 92.3% on time and worst on Saturday at 73.1%. Each day rests on about 52 flights, so a gap of 19 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 1202 runs late

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 3,446 reported delay minutes.

  • National Airspace System
    32%
  • Carrier
    26%
  • Late-arriving aircraft
    22%
  • Extreme weather
    19%

Extreme weather accounts for 19% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 3.1 times the usual weather exposure. The split is drawn from 3,446 delay minutes reported on DL 1202.

Cancellations are rare at 0.82%, 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 3.3% 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.

The 626 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

Every one of the 364 flights under DL 1202 in the data flew SLC to SAN. 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. 364 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 1202

For a booking, read DL 1202 as 84.4% on time with 0.82% cancelled over 364 flights. Those are rates from the past twelve months, not a forecast for any particular day.
