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 19 points, against half a point between the best and worst carrier.

  • 8am–11am111 flights78.5%
  • 11am–2pm38 flights92.1%

Scale runs 65% to 100%. Rows with fewer than 30 flights show a dash.

The best window here is not the first bank but the 11am–2pm slot at 92.1% on time, ahead of 5pm–8pm at 73.0%. Where the curve peaks mid-day rather than at dawn, the constraint is usually congestion at one end rather than the aircraft's own rotation. The 5am–8am window is the busiest, with 360 flights scheduled in it.

Delay causes

Why SkyWest runs late on this route

Carrier accounts for 51% of the 15,000 delay minutes carriers reported here, and the remaining four split what is left.

  • Carrier
    51%
  • Late-arriving aircraft
    25%
  • National Airspace System
    20%
  • Extreme weather
    4%

The largest share of delay minutes, 51%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 7,683 of the 15,000 delay minutes reported here. The split is drawn from 14,973 reported delay minutes.

Cancellations sit at 1.02% against a national 1.89%, which is ordinary. Diversions add another 0.00%.

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.

At 261 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 11am–2pm window matters as much as it does.

The return leg is a different operation and performs like one: it runs 75.8% on time across 684 flights, 6 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 6 points of difference.

One caution: this is a thin sample. 684 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 PSP to PHX

Put together: treat all of this as provisional. 684 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 81.5% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 677 completed flights over 12 months sit behind that.
