These figures cover 365 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 2651 flies

DL 2651 flies MSP to SLC without a single fixed slot. Its most common scheduled departure was 12:45, used on 106 of 365 flights, with 11:00 (100 flights) and 12:40 (41 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

A 12:45 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and DL 2651 runs 10 points better at 89.2%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

DL 2651 quarter by quarter

DL 2651 did not run the same all year. Its best quarter was Apr–Jun 2026 at 95.6% on time and its weakest Jan–Mar 2026 at 83.0%, a swing of 13 points on roughly 91 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 2651 did best on Thursday at 96.2% on time and worst on Wednesday at 80.4%. Each day rests on about 52 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 2651 runs late

One category carries most of the weight here. Carrier accounts for 62% of the 2,266 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.

National Airspace System
23%
Late-arriving aircraft
13%
Extreme weather
2%

The largest share of delay minutes, 62%, 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 1,413 of the 2,266 delay minutes reported here. The split is drawn from 2,266 delay minutes reported on DL 2651.

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 4.4% 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 991 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 365 flights under DL 2651 in the data flew MSP 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. 365 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 2651

For a booking, DL 2651 has one of the better records a US domestic flight can show: 89.2% on time and 0.82% cancelled. That is a base rate, not a promise about any single day.
