Historical statistics for July 2025 to June 2026, not live status. For today’s OO 4067, 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 4067 lands a B+, 6 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by close to two hours on average. That is a workable record, not a spotless one. That rests on 307 flights, with a median arrival 11 minutes early.

Set against the rest of the country, OO 4067's record is 6 points better than the US average of 77.6%. That gap is worth roughly 56 fewer late arrivals for every thousand flights.

These figures cover 307 flights between July 2025 and June 2026. The median arrival is 11 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Schedule

When OO 4067 flies

OO 4067 flies AUS to MFE without a single fixed slot. Its most common scheduled departure was 22:35, used on 65 of 307 flights, with 22:33 (35 flights) and 22:41 (31 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 22:35 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and OO 4067 runs 13 points better at 83.2%. 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 4067 quarter by quarter

OO 4067 did not run the same all year. Its best quarter was Oct–Dec 2025 at 91.2% on time and its weakest Apr–Jun 2026 at 77.3%, a swing of 14 points on roughly 77 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.

Oct–Dec 202580 flights91.2%
Jan–Mar 202676 flights77.3%

Scale runs 70% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, OO 4067 did best on Wednesday at 89.8% on time and worst on Sunday at 72.3%. Each day rests on about 44 flights, so a gap of 18 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 4067 runs late

One category carries most of the weight here. Carrier accounts for 49% of the 5,669 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
49%
National Airspace System
29%
Extreme weather
21%

Extreme weather accounts for 21% 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 3.4 times the usual weather exposure. The split is drawn from 5,669 delay minutes reported on OO 4067.

Cancellations are rare at 0.65%, 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

7.6% 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 close to two hours, which a normal layover absorbs.

Every one of the 307 flights under OO 4067 in the data flew AUS to MFE. 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. 307 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.

Booking OO 4067
