Historical statistics for July 2025 to June 2026, not live status. For today’s OO 4016, check with SkyWest Airlines. SkyWest Airlines flies under contract for larger airlines, so a ticket for this flight may show a different airline code and number.

OO 4016 lands a B+, 3 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 a little over an hour on average. That is a workable record, not a spotless one. That rests on 365 flights, with a median arrival 11 minutes early.

These figures cover 365 flights between July 2025 and June 2026. Beyond the headline rate, 8.6% 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 4016 flies

OO 4016 flies AUS to MSY without a single fixed slot. Its most common scheduled departure was 13:55, used on 61 of 365 flights, with 13:59 (40 flights) and 07:35 (37 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 13:55 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and OO 4016 runs level with that at 80.4%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

OO 4016 quarter by quarter

OO 4016 did not run the same all year. Its best quarter was Jul–Sep 2025 at 93.5% on time and its weakest Jan–Mar 2026 at 66.3%, a swing of 27 points on roughly 91 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.

Jul–Sep 202592 flights93.5%
Oct–Dec 202592 flights82.6%
Jan–Mar 202690 flights66.3%

By weekday, OO 4016 did best on Saturday at 88.2% on time and worst on Wednesday at 73.1%. Each day rests on about 52 flights, so a gap of 15 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 4016 runs late

One category carries most of the weight here. Carrier accounts for 64% of the 5,702 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%
Extreme weather
22%
National Airspace System
13%
Security
1%

Extreme weather accounts for 22% 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 3.6 times the usual weather exposure. The split is drawn from 5,702 delay minutes reported on OO 4016.

Cancellations are rare at 0.27%, 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 routes

What a delay on this flight costs

8.6% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.

OO 4016 is not only a AUS to MSY flight. It also flew MSY to AUS (365 flights, 80.4% 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. 365 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.
