Schedule

When OO 6474 flies

OO 6474 flies PHX to FLG without a single fixed slot. Its most common scheduled departure was 19:00, used on 41 of 258 flights, with 22:00 (37 flights) and 22:50 (34 flights) next.

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

A 19:00 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and OO 6474 runs 5 points better at 73.5%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year

OO 6474 quarter by quarter

OO 6474 did not run the same all year. Its best quarter was Apr–Jun 2026 at 79.5% on time and its weakest Jul–Sep 2025 at 67.2%, a swing of 12 points on roughly 65 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.

By weekday, OO 6474 did best on Thursday at 80.0% on time and worst on Sunday at 55.8%. Each day rests on about 37 flights, so a gap of 24 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 6474 runs late

One category carries most of the weight here. Carrier accounts for 65% of the 16,000 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.

The largest share of delay minutes, 65%, 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 10,000 of the 16,000 delay minutes reported here. The split is drawn from 16,014 delay minutes reported on OO 6474.

Cancellations sit at 1.94% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 13.4% 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.

Every one of the 258 flights under OO 6474 in the data flew PHX to FLG. The number was not reused on any other city pair, which makes this a clean record of one route.

One caution: this is a thin sample. 258 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 6474

For a booking, OO 6474 is a flight to put a long connection behind. 13.4% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
