These figures cover 2,107 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.

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 16 points, against half a point between the best and worst carrier.
- 5am–8am343 flights85.9%
- 8am–11am365 flights82.8%
- 11am–2pm592 flights86.2%
- 2pm–5pm222 flights85.0%
- 5pm–8pm339 flights70.0%
- 8pm–5am246 flights74.5%
Scale runs 60% to 90%.
The best window here is not the first bank but the 11am–2pm slot at 86.2% on time, ahead of 5pm–8pm at 70.0%. Where the curve peaks mid-day rather than at dawn, the constraint is usually congestion at one end rather than the aircraft's own rotation. The 11am–2pm window is the busiest, with 592 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 29 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 63.8% on time, against 92.7% in September. 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. July was the busiest month here, with 208 flights.
Across the week, Tuesday is the strongest day at 88.4% on time and Sunday the weakest at 74.1%, a spread of 14 points.
Delay causes
Why this route gets delayed
Carrier accounts for 52% of the 20,000 delay minutes carriers reported here, and the remaining four split what is left.
- 52%Carrier
- 24%Late-arriving aircraft
- 23%National Airspace System
- 2%Extreme weather
The largest share of delay minutes, 52%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 10,000 of the 20,000 delay minutes reported here. The split is drawn from 19,923 reported delay minutes.
Cancellations sit at 1.00% against a national 1.89%, which is ordinary. Diversions add another 0.09%.
Connections and stage length
What a delay here actually costs
Badly late arrivals are rare here: only 4.6% 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.
At 1,535 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.
The return leg is a different operation and performs like one: it runs 86.2% on time across 2,109 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 2,107 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 92.7% on time and December 63.8%, a swing of 29 points. If the dates move at all, move them out of December before you think about anything else. 2,084 completed flights over 12 months sit behind that.
Common questions
MSP to LAX questions
How often is MSP to LAX delayed?
Roughly 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 18.5% of the 2,107 flights in this analysis, against 22.7% nationally. Delayed flights are late by roughly 50 minutes on average.
How reliable is MSP to LAX compared with the rest of the country?
81.5% of flights arrive on time here against a national 77.3%, a difference of 4 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 LAX?
The 11am–2pm departure window is the strongest at 86.2% on time. The 5pm–8pm window is the weakest at 70.0%, 16 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 LAX?
December is the weakest month at 63.8% on time, compared with 92.7% in September. Across the year that is 29 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
