These figures cover 622 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.

Darker means more delays. Figures are on-time percentages.February best, December worst

December is the weak month at 72.1% on time, against 89.1% in February. 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. January was the busiest month here, with 62 flights.

Across the week, Wednesday is the strongest day at 88.6% on time and Sunday the weakest at 80.7%, a spread of 8 points.

Delay causes

Why SkyWest runs late on this route

Carrier accounts for 42% of the 5,374 delay minutes carriers reported here, and the remaining four split what is left.

  • Carrier
    42%
  • Late-arriving aircraft
    33%
  • National Airspace System
    21%
  • Extreme weather
    4%

The largest share of delay minutes, 42%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,265 of the 5,374 delay minutes reported here. The split is drawn from 5,374 reported delay minutes.

Cancellations are rare at 0.00%, below the national 1.89% and low enough to earn the plus on the grade. Almost no flights are called off; the risk here is arriving late, not not arriving.

Connections and stage length

What a delay here 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 959 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 92.9% on time across 626 flights, 8 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 8 points of difference.

One caution: this is a thin sample. 622 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 SkyWest on DEN to MRY

Put together: treat all of this as provisional. 622 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 84.5% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 619 completed flights over 12 months sit behind that.
