Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with SkyWest Airlines.
SkyWest on PHX to MFR lands a B+, about a point better than the national rate of 77.3%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That rests on 516 flights, with a median arrival 9 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate SkyWest on PHX to MFR from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Carrier by carrier
SkyWest against every carrier on PHX to MFR
SkyWest flew 516 of the 754 flights on PHX to MFR, most of the route. Its 78.2% on time is 3 points worse than the route as a whole, which runs 80.9%. Ranked by on-time rate it is last of two carriers on the route, where the range runs from Envoy at 86.8% to SkyWest at 78.2%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

Departure window
When SkyWest runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 21 points, against half a point between the best and worst carrier.
- 5am–8am—
- 8am–11am205 flights83.9%
- 11am–2pm43 flights62.8%
- 2pm–5pm55 flights78.2%
- 5pm–8pm25 flights—
- 8pm–5am188 flights76.3%
Scale runs 55% to 90%. Rows with fewer than 30 flights show a dash.
The weak window here is the middle of the day, not the evening: 11am–2pm runs 62.8% on time against 83.9% for 8am–11am. That shape usually means a departure bank rather than an accumulating delay, so the recovery later in the afternoon is real rather than noise. The 8am–11am window is the busiest, with 205 flights scheduled in it.
Across the year
SkyWest on PHX to MFR through the year
December is the weak month at 60.0% on time, against 92.9% 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. March was the busiest month here, with 62 flights.
Across the week, Wednesday is the strongest day at 83.1% on time and Saturday the weakest at 68.6%, a spread of 15 points.

The worst days
Worst days for SkyWest on PHX to MFR
The latest arrival of the period was on 21 March 2026, 12 hours 41 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. Three of the five worst days fell in July 2026.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 21 March 2026 | 12 hours 41 minutes | Late-arriving aircraft |
| 2 July 2026 | 10 hours 17 minutes | Carrier |

Delay causes
Why SkyWest runs late on this route
Late-arriving aircraft accounts for 55% of the 9,039 delay minutes carriers reported here, and the remaining four split what is left.
- 55%Late-arriving aircraft
- 36%Carrier
- 5%National Airspace System
- 4%Extreme weather
55% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 9,039 reported delay minutes here, that single category outweighs weather by 14 to one. The split is drawn from 9,039 reported delay minutes.
The largest share of delay minutes, 36%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 3,259 of the 9,039 delay minutes reported here.
Cancellations are rare at 0.19%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and stage length
What a delay here costs
9.0% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
The 855 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 83.4% on time across 516 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.
One caution: this is a thin sample. 516 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 PHX to MFR
Put together: treat all of this as provisional. 516 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 78.2% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 513 completed flights over 12 months sit behind that.
