These figures cover 349 flights between July 2025 and June 2026. Beyond the headline rate, 9.3% 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.

Schedule

When OO 3772 flies

OO 3772 flies JAX to AUS without a single fixed slot. Its most common scheduled departure was 14:26, used on 56 of 349 flights, with 14:21 (41 flights) and 15:42 (36 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 14:26 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and OO 3772 runs 8 points better at 80.8%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

OO 3772 quarter by quarter

OO 3772 did not run the same all year. Its best quarter was Oct–Dec 2025 at 86.2% on time and its weakest Jul–Sep 2025 at 70.7%, a swing of 16 points on roughly 87 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 3772 did best on Sunday at 87.5% on time and worst on Thursday at 72.0%. Each day rests on about 50 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 3772 runs late

One category carries most of the weight here. Carrier accounts for 68% of the 8,608 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
68%
Extreme weather
25%
National Airspace System
6%

Extreme weather accounts for 25% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 4.0 times the usual weather exposure. The split is drawn from 8,608 delay minutes reported on OO 3772.

Cancellations sit at 1.72% 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. 9.3% 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 953 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.

OO 3772 is not only a JAX to AUS flight. It also flew AUS to JAX (349 flights, 86.8% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.

One caution: this is a thin sample. 349 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.
