This route lands a B, 4 points better than the national rate of 77.3%. About one flight in five arrives 15 minutes late or worse, and those flights are late by about 55 minutes on average. That rests on 838 MSP to BDL flights, with a median arrival 8 minutes early.
Best time to fly MSP to BDL: a 5am–8am departure, ideally on a Wednesday. Flights in that window arrived on time 89.1% of the time and Wednesday flights 87.8%, against 80.8% for the route overall.
The US average over the same twelve months is 77.3%, so there is little to separate this route from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

These figures cover 838 flights between September 2025 and August 2026. The median arrival is 8 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.

Book the early departure. Flights leaving between 5am–8am arrive on time 89.1% of the time, against 76.4% for the afternoon window. That is 13 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8pm–5am window is the busiest, with 329 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 16 points from best month to worst, which is wide. An annual average tells you very little about the week you are actually flying, so read the strip rather than the headline if your dates are fixed.
December is the weak month at 72.4% on time, against 88.1% in November. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. August was the busiest month here, with 87 flights.
Across the week, Wednesday is the strongest day at 87.8% on time and Monday the weakest at 73.8%, a spread of 14 points.
Delay causes
Why this route gets delayed
Carrier accounts for 62% of the 8,493 delay minutes carriers reported here, and the remaining four split what is left.
- 62%Carrier
- 16%Late-arriving aircraft
- 16%National Airspace System
- 6%Extreme weather
The largest share of delay minutes, 62%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 5,241 of the 8,493 delay minutes reported here. The split is drawn from 8,493 reported delay minutes.
Cancellations sit at 2.27% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and stage length
What a delay here actually costs
6.3% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about 55 minutes, which a normal layover absorbs.
The 1,050 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 return leg runs 82.5% on time across 837 flights, within 2 points of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
One caution: this is a thin sample. 838 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 this route
Put together: treat all of this as provisional. 838 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 80.8% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 819 completed flights over 12 months sit behind that.

The 5am–8am departure window is the strongest at 89.1% on time. The 2pm–5pm window is the weakest at 76.4%, 13 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.
How bad are December delays on MSP to BDL?
