Departure window

The best time of day to leave PHX in June

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 33 points, against 25 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

5am–8am1,956 flights90.7%
8am–11am3,925 flights81.9%
11am–2pm2,158 flights73.3%
2pm–5pm2,749 flights65.1%
5pm–8pm2,291 flights57.4%
8pm–5am2,606 flights64.4%

Scale runs 50% to 95%. Rows with fewer than 30 flights show a dash.

The 5pm–8pm window is where this operation falls apart: 57.4% on time, against 90.7% for the 5am–8am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 8am–11am window is the busiest, with 3,925 flights scheduled in it.

Across the week, Tuesday is the strongest day at 77.0% on time and Sunday the weakest at 66.9%. 10 points is a smaller lever than departure hour, but it is free.

Carrier by carrier

Which airlines ran best at PHX in June

The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 87.7% of the time; Southwest Airlines manages 63.2%. Sample sizes sit next to every figure, because a two-point gap across 5,220 flights means less than a ten-point one.

The spread between Delta and Southwest is 25 points, wide enough that it should decide the booking. On a hundred trips that is 25 more arrivals inside the on-time window.

Delay causes

What held PHX up in June

One category carries most of the weight here. Late-arriving aircraft accounts for 47% of the 279,000 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.

47% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 279,000 reported delay minutes here, that single category outweighs weather by 47 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 279,209 reported delay minutes.

Cancellations are rare at 0.43%, below the national 1.65% 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.

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 9.0% of arrivals land a full hour or more behind schedule, against 9.7% 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.

What to do with this

Flying from PHX in June

For a June trip through PHX: plan on this being one of the airport's harder months. The 5am–8am departures held up best at 90.7% on time, and with 9.0% of arrivals an hour or more late, a connection here deserves more slack than the same trip in February would.
