Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with SkyWest Airlines.
SkyWest on DEN to MFR lands a B+, level with the national rate of 77.3%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by about an hour on average. That rests on 156 flights, with a median arrival 2 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate SkyWest on DEN to MFR from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

These figures cover 156 flights between September 2025 and August 2026. The median arrival is 2 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
When SkyWest runs best on this route
Departure time is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 156 flights.
There are not enough flights in each departure window to split SkyWest's DEN to MFR record by time of day without the percentages moving on noise. The headline rate of 77.9% is the reliable figure here.

Split by quarter, SkyWest on DEN to MFR logged 69 flights in Oct–Dec 2025 and 87 flights in Jan–Mar 2026. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 77.9% annual figure is the one to use.

Share of 154 completed flights by arrival against schedule.
7 of 28 late departures made up the time and arrived on time, 25% of them. In the other direction, 13 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at MFR.
The worst days
Worst days for SkyWest on DEN to MFR
The latest arrival of the period was on 30 November 2025, 4 hours 3 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The five worst days are spread across November, February, December and January, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 30 November 2025 | 4 hours 3 minutes | Late-arriving aircraft |
| 17 February 2026 | 2 hours 35 minutes | Extreme weather |

Delay causes
Why SkyWest runs late on this route
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 1,934 reported delay minutes.
- 37%Carrier
- 27%Late-arriving aircraft
- 20%Extreme weather
- 16%National Airspace System
Extreme weather accounts for 20% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the monthly strip above is the more useful view of the risk. The national share is 6%, so this operation carries roughly 3.4 times the usual weather exposure. The split is drawn from 1,934 reported delay minutes.
The largest share of delay minutes, 37%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 711 of the 1,934 delay minutes reported here.
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
5.8% 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 964 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 76.0% on time across 154 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. 156 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 MFR
Put together: treat all of this as provisional. 156 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 77.9% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 154 completed flights over 12 months sit behind that.
