These figures cover 365 flights between September 2025 and August 2026. The median arrival is 20 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.

| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 6 June 2026 | 8 hours 13 minutes | Late-arriving aircraft |
| 9 October 2025 | 3 hours 10 minutes | Carrier |

Delay causes
Why DL 943 runs late
Carrier accounts for 66% of the 1,567 delay minutes carriers reported here, and the remaining four split what is left.
- 66%Carrier
- 29%Late-arriving aircraft
- 6%National Airspace System
The largest share of delay minutes, 66%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,028 of the 1,567 delay minutes reported here. The split is drawn from 1,567 delay minutes reported on DL 943.
Cancellations are rare at 0.82%, 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 1.9% 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 1,399 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.
Every one of the 365 flights under DL 943 in the data flew SEA to MSP. 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 943
For a booking, DL 943 has one of the better records a US domestic flight can show: 96.4% on time and 0.82% cancelled. That is a base rate, not a promise about any single day.
