Historical statistics for July 2025 to June 2026, not live status. For today’s OO 4944, check with SkyWest Airlines. SkyWest Airlines flies under contract for larger airlines, so a ticket for this flight may show a different airline code and number.

OO 4944 earns an A+. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 13 points better than the national rate of 77.6%.

These figures cover 279 flights between July 2025 and June 2026. The median arrival is 13 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.

Schedule

When OO 4944 flies

OO 4944 flies PHX to PSC without a single fixed slot. Its most common scheduled departure was 10:45, used on 60 of 279 flights, with 12:20 (45 flights) and 11:30 (37 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 10:45 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and OO 4944 runs 7 points better at 90.7%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

OO 4944 quarter by quarter

Quarter by quarter OO 4944 held fairly steady: 92.3% in Jul–Sep 2025, 91.3% in Oct–Dec 2025 and 87.8% in Jan–Mar 2026. A spread of 5 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, OO 4944 did best on Thursday at 100.0% on time and worst on Saturday at 82.5%. Each day rests on about 40 flights, so a gap of 18 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 4944 runs late

One category carries most of the weight here. Carrier accounts for 71% of the 1,953 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

Carrier
71%
Late-arriving aircraft
22%
Extreme weather
6%
National Airspace System
1%

The largest share of delay minutes, 71%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 1,396 of the 1,953 delay minutes reported here. The split is drawn from 1,953 delay minutes reported on OO 4944.

Cancellations are rare at 0.00%, below the national 1.81% 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 routes

What a delay on this flight costs

5.0% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.

The 962 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

The same number turns up on four other city pairs in the data, including PSC to PHX (167), SLC to PHX (44) and BUR to PHX (41), but none flew often enough under OO 4944 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to PHX to PSC only.

One caution: this is a thin sample. 279 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 OO 4944

For a booking, OO 4944 has one of the better records a US domestic flight can show: 90.7% on time and 0.00% cancelled. That is a base rate, not a promise about any single day.
