This route earns a B+. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 7 points better than the national rate of 77.3%. When something does go wrong the average delay runs an hour and a half. That rests on 2,091 LAS to MSP flights, with a median arrival 11 minutes early.
Best time to fly LAS to MSP: a 8am–11am departure, ideally on a Tuesday. Flights in that window arrived on time 92.1% of the time and Tuesday flights 89.8%, against 84.7% for the route overall.
Set against the rest of the country, this route's record is 7 points better than the US average of 77.3%. That gap is worth roughly 74 fewer late arrivals for every thousand flights.

These figures cover 2,091 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.

Departure window
The best time of day to leave
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 15 points, against half a point between the best and worst carrier.
- 5am–8am374 flights91.8%
- 8am–11am410 flights92.1%
- 11am–2pm449 flights81.8%
- 2pm–5pm329 flights78.2%
- 5pm–8pm366 flights76.9%
- 8pm–5am163 flights88.2%
Scale runs 70% to 100%.
Book the morning departure. Flights leaving between 8am–11am arrive on time 92.1% of the time, against 76.9% for the evening window. That is 15 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 11am–2pm window is the busiest, with 449 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.
July is the worst month at 74.3% on time, 16 points below April, the best at 90.5%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck. March was the busiest month here, with 215 flights.
Across the week, Tuesday is the strongest day at 89.8% on time and Friday the weakest at 78.8%, a spread of 11 points.
Delay causes
Why this route gets delayed
Carrier accounts for 52% of the 26,000 delay minutes carriers reported here, and the remaining four split what is left.
- 52%Carrier
- 38%Late-arriving aircraft
- 9%National Airspace System
- 1%Extreme weather
- 0%Security
38% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 26,000 reported delay minutes here, that single category outweighs weather by 30 to one. The split is drawn from 26,043 reported delay minutes.
The largest share of delay minutes, 52%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 13,000 of the 26,000 delay minutes reported here.
Cancellations sit at 0.96% against a national 1.89%, which is ordinary. Diversions add another 0.14%.
Connections and stage length
What a delay here actually costs
Badly late arrivals are rare here: only 4.7% 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 1,299 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 is a different operation and performs like one: it runs 80.1% on time across 2,086 flights, 5 points below this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 5 points of difference.
The sample behind these figures is 2,091 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.

What to do with this
Booking this route
Put together: the calendar is the biggest lever here, not the carrier or the hour. April runs 90.5% on time and July 74.3%, a swing of 16 points. If the dates move at all, move them out of July before you think about anything else. 2,068 completed flights over 12 months sit behind that.

The 8am–11am departure window is the strongest at 92.1% on time. The 5pm–8pm window is the weakest at 76.9%, 15 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 July delays on LAS to MSP?
