These figures cover 356 flights between September 2025 and August 2026. The median arrival is 11 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.

| 23 July 2026 | 3 hours 36 minutes | Carrier |

Delay causes
Why DL 2649 runs late
Carrier accounts for 50% of the 1,476 delay minutes carriers reported here, and the remaining four split what is left.
- 50%Carrier
- 46%National Airspace System
- 4%Late-arriving aircraft
- 0%Extreme weather
46% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 678 minutes out of 1,476, against a national NAS share of 21%. The split is drawn from 1,476 delay minutes reported on DL 2649.
Cancellations sit at 1.40% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 1.4% 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 1,124 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.
The same number turns up on one other city pair in the data, including MSP to MSN (1), but none flew often enough under DL 2649 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to MSP to BOS only.
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 2649
For a booking, DL 2649 has one of the better records a US domestic flight can show: 89.5% on time and 1.40% cancelled. That is a base rate, not a promise about any single day.
