Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with SkyWest Airlines.

SkyWest on PHX to TUL lands a B+, 2 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That is a workable record, not a spotless one. That rests on 404 flights, with a median arrival 3 minutes early.

The US average over the same twelve months is 77.6%, so there is little to separate SkyWest on PHX to TUL from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

These figures cover 404 flights between July 2025 and June 2026. Beyond the headline rate, 9.5% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Carrier by carrier

SkyWest against every carrier on PHX to TUL

SkyWest flew 404 of the 1,277 flights on PHX to TUL, about 32% of it. Its 79.1% on time is 4 points better than the route as a whole, which runs 75.1%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from Envoy at 81.5% to Southwest at 69.4%. 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 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 404 flights.

  • 5am–8am
  • 8am–11am195 flights84.0%
  • 11am–2pm5 flights
  • 2pm–5pm
  • 5pm–8pm81 flights75.3%
  • 8pm–5am123 flights74.6%

Scale runs 65% to 90%. Rows with fewer than 30 flights show a dash.

Book the morning departure. Flights leaving between 8am–11am arrive on time 84.0% of the time, against 74.6% for the overnight window. That is 9 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8am–11am window is the busiest, with 195 flights scheduled in it.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 79.1% on time across 404 flights.

SkyWest on PHX to TUL did not run the same all year. Its best quarter was Apr–Jun 2026 at 86.0% on time and its weakest Jan–Mar 2026 at 72.5%, a swing of 14 points on roughly 135 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

Across the week, Friday is the strongest day at 85.5% on time and Tuesday the weakest at 73.7%. 12 points is a smaller lever than departure hour, but it is free.

Delay causes

Why SkyWest runs late on this route

One category carries most of the weight here. Carrier accounts for 64% of the 7,786 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
    64%
  • Late-arriving aircraft
    25%
  • Extreme weather
    6%
  • National Airspace System
    5%

The largest share of delay minutes, 64%, 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 5,016 of the 7,786 delay minutes reported here. The split is drawn from 7,786 reported delay minutes.

Cancellations are rare at 0.25%, below the national 1.81% 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

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 9.5% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

The 935 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 return leg runs 81.0% on time across 402 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. 404 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 TUL

Put together: treat all of this as provisional. 404 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 79.1% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 402 completed flights over 12 months sit behind that.
