These figures cover 356 flights between July 2025 and June 2026. The median arrival is 6 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 2437 flies

DL 2437 flies MSP to GEG without a single fixed slot. Its most common scheduled departure was 11:59, used on 127 of 356 flights, with 12:13 (37 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 11:59 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and DL 2437 runs 9 points better at 88.1%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

DL 2437 quarter by quarter

DL 2437 did not run the same all year. Its best quarter was Jul–Sep 2025 at 94.5% on time and its weakest Jan–Mar 2026 at 80.5%, a swing of 14 points on roughly 89 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 202591 flights94.5%

By weekday, DL 2437 did best on Tuesday at 95.9% on time and worst on Sunday at 80.4%. Each day rests on about 51 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 2437 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 1,871 reported delay minutes.

National Airspace System
36%
Carrier
33%
Late-arriving aircraft
16%
Extreme weather
14%

Extreme weather accounts for 14% 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 2.3 times the usual weather exposure. The split is drawn from 1,871 delay minutes reported on DL 2437.

Cancellations are rare at 0.84%, 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 2.3% 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 1,175 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.

DL 2437 is not only a MSP to GEG flight. It also flew GEG to MSP (356 flights, 89.2% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.

One caution: this is a thin sample. 356 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.
