These figures cover 356 flights between September 2025 and August 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.

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 96.7% on time and its weakest Jan–Mar 2026 at 80.5%, a swing of 16 points on roughly 71 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.

- Oct–Dec 202589 flights81.8%
- Jan–Mar 202685 flights80.5%

Scale runs 70% to 100%.
By weekday, DL 2437 did best on Tuesday at 95.8% on time and worst on Friday at 80.8%. Each day rests on about 51 flights, so a gap of 15 points is worth noticing but could still narrow in another year.

Share of 352 completed flights by arrival against schedule.
A late pushback is often recovered here: of 34 departures that left 15 minutes late or more, 12 still arrived on time. In the other direction, 20 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at GEG.
The worst days
Worst days for DL 2437
The latest arrival of the period was on 27 December 2025, 4 hours behind schedule; most of its delay minutes were filed as extreme weather. On three of the five worst days the largest share was filed as carrier-caused (crew, maintenance, fuelling, baggage).
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 27 December 2025 | 4 hours | Extreme weather |
| 19 August 2026 | 2 hours 13 minutes | Carrier |
| 29 May 2026 | 2 hours 7 minutes | Carrier |
| 8 November 2025 | 1 hour 27 minutes | Late-arriving aircraft |

Delay causes
Why DL 2437 runs late
Carrier accounts for 42% of the 1,991 delay minutes carriers reported here, and the remaining four split what is left.
- 42%Carrier
- 33%National Airspace System
- 14%Extreme weather
- 11%Late-arriving aircraft
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 1,991 delay minutes reported on DL 2437.
Cancellations are rare at 0.84%, below the national 1.89% 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 8.3% 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.
DL 2437 is not only a MSP to GEG flight. It also flew GEG to MSP (355 flights, 89.8% 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.

What to do with this
Booking DL 2437
For a booking, DL 2437 has one of the better records a US domestic flight can show: 88.1% on time and 0.84% cancelled. That is a base rate, not a promise about any single day.
