This route lands a B, 3 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 an hour on average. That rests on 2,086 MSP to LAS flights, with a median arrival 6 minutes early.
Best time to fly MSP to LAS: a 5am–8am departure, ideally on a Tuesday. Flights in that window arrived on time 89.6% of the time and Tuesday flights 85.2%, against 80.1% 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 2,086 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.

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 25 points, against half a point between the best and worst carrier.

Scale runs 55% to 95%.
Book the early departure. Flights leaving between 5am–8am arrive on time 89.6% of the time, against 65.1% for the evening window. That is 25 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5am–8am window is the busiest, with 467 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 25 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.
August is the worst month at 68.5% on time, 25 points below September, the best at 93.4%. 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 85.2% on time and Monday the weakest at 76.8%, a spread of 8 points.
Delay causes
Why this route gets delayed
Carrier accounts for 56% of the 25,000 delay minutes carriers reported here, and the remaining four split what is left.
- 56%Carrier
- 22%National Airspace System
- 16%Late-arriving aircraft
- 5%Extreme weather
The largest share of delay minutes, 56%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 14,000 of the 25,000 delay minutes reported here. The split is drawn from 25,365 reported delay minutes.
Cancellations sit at 1.05% against a national 1.89%, which is ordinary. Diversions add another 0.14%.
Connections and stage length
What a delay here actually costs
6.1% 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 an hour, which a normal layover absorbs.
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 84.7% on time across 2,091 flights, 5 points above 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 2,086 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. September runs 93.4% on time and August 68.5%, a swing of 25 points. If the dates move at all, move them out of August before you think about anything else. 2,061 completed flights over 12 months sit behind that.
Common questions

About one flight in five arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 19.9% of the 2,086 flights in this analysis, against 22.7% nationally. Delayed flights are late by about an hour on average.
How reliable is MSP to LAS compared with the rest of the country?
80.1% of flights arrive on time here against a national 77.3%, a difference of 3 points in its favour. That is worth a B on this site's grading scale.
What time of day has the fewest delays on MSP to LAS?
The 5am–8am departure window is the strongest at 89.6% on time. The 5pm–8pm window is the weakest at 65.1%, 25 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 August delays on MSP to LAS?
August is the weakest month at 68.5% on time, compared with 93.4% in September. Across the year that is 25 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
