Every carrier on MFR to PHX, 754 flights
These figures cover 516 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.

Carrier by carrier
SkyWest against every carrier on MFR to PHX
SkyWest flew 516 of the 754 flights on MFR to PHX, most of the route. Its 83.4% on time is about level with the route as a whole at 84.4%. Ranked by on-time rate it is last of two carriers on the route, where the range runs from Envoy at 86.4% to SkyWest at 83.4%. 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 23 points, against half a point between the best and worst carrier.
- 5am–8am256 flights92.9%
- 8am–11am10 flights—
- 11am–2pm80 flights70.0%
- 2pm–5pm160 flights77.5%
- 5pm–8pm9 flights—
- 8pm–5am1 flights—
Scale runs 60% to 100%. 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 70.0% on time against 92.9% for 5am–8am. 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 5am–8am window is the busiest, with 256 flights scheduled in it.
Across the year
SkyWest on MFR to PHX through the year
February is the weak month at 69.7% 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, Thursday is the strongest day at 87.7% on time and Saturday the weakest at 78.6%, a spread of 9 points.

Worst days for SkyWest on MFR to PHX
The latest arrival of the period was on 28 April 2026, 11 hours 20 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. On four of the five worst days the largest share was filed as carrier-caused (crew, maintenance, fuelling, baggage).
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 28 April 2026 | 11 hours 20 minutes | Late-arriving aircraft |
| 2 January 2026 | 10 hours 11 minutes | Carrier |

Delay causes
Why SkyWest runs late on this route
Carrier accounts for 61% of the 8,014 delay minutes carriers reported here, and the remaining four split what is left.
- 61%Carrier
- 31%Late-arriving aircraft
- 5%Extreme weather
- 3%National Airspace System
- 0%Security
The largest share of delay minutes, 61%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 4,882 of the 8,014 delay minutes reported here. The split is drawn from 8,014 reported delay minutes.
The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 92.9% on time here.
Cancellations are rare at 0.39%, 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
6.8% 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 an hour and a half, which a normal layover absorbs.
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 78.2% on time across 516 flights, 5 points below 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 MFR to PHX
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 83.4% 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.
