Historical statistics for July 2025 to June 2026, not live status. For today’s OO 4060, 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 4060 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 about 2.4 hours on average. That is a workable record, not a spotless one. That rests on 295 flights, with a median arrival 11 minutes early.

Set against the rest of the country, OO 4060's record is 6 points better than the US average of 77.6%. That gap is worth roughly 63 fewer late arrivals for every thousand flights.

These figures cover 295 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 4060 flies

OO 4060 flies LAN to DTW without a single fixed slot. Its most common scheduled departure was 05:35, used on 126 of 295 flights, with 05:30 (40 flights) and 05:40 (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 05:35 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and OO 4060 runs 5 points worse at 83.9%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

OO 4060 quarter by quarter

OO 4060 did not run the same all year. Its best quarter was Jul–Sep 2025 at 96.7% on time and its weakest Jan–Mar 2026 at 71.1%, a swing of 26 points on roughly 74 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 flights96.7%
Oct–Dec 202557 flights77.2%
Jan–Mar 202686 flights71.1%
Apr–Jun 202660 flights88.3%

Scale runs 65% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, OO 4060 ranged from 79.1% on Wednesday to 88.1% on Friday. With about 42 flights behind each day, a spread of 9 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why OO 4060 runs late

One category carries most of the weight here. Carrier accounts for 90% of the 6,737 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
90%
Extreme weather
6%
National Airspace System
4%

The largest share of delay minutes, 90%, 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 6,058 of the 6,737 delay minutes reported here. The split is drawn from 6,737 delay minutes reported on OO 4060.

Cancellations sit at 1.02% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

7.5% 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 about 2.4 hours, which a normal layover absorbs.

Every one of the 295 flights under OO 4060 in the data flew LAN to DTW. 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. 295 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.
