Historical statistics for July 2025 to June 2026, not live status. For today’s OO 6405, 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 6405 sits in the middle of the pack with a C−. Close to three flights in four arrive on time by the DOT's definition, 4 points worse than the national rate of 77.6%. The late ones land a little over an hour behind schedule. That rests on 361 flights, with a median arrival 4 minutes early.

The national on-time rate over the same period is 77.6%, so OO 6405 runs 4 points behind the country as a whole. Across a thousand flights that is about 41 extra late arrivals.

These figures cover 361 flights between July 2025 and June 2026. Beyond the headline rate, 12.2% 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 6405 flies

OO 6405 flies DFW to SAF without a single fixed slot. Its most common scheduled departure was 20:04, used on 55 of 361 flights, with 20:10 (54 flights) and 20:05 (44 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 20:04 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and OO 6405 runs 3 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 6405 quarter by quarter

OO 6405 did not run the same all year. Its best quarter was Jan–Mar 2026 at 78.3% on time and its weakest Jul–Sep 2025 at 65.2%, a swing of 13 points on roughly 90 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.

Scale runs 55% to 85%. Rows with fewer than 30 flights show a dash.

By weekday, OO 6405 did best on Tuesday at 81.2% on time and worst on Thursday at 66.0%. 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 6405 runs late

One category carries most of the weight here. Carrier accounts for 43% of the 7,431 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
43%
Extreme weather
25%
Late-arriving aircraft
22%
National Airspace System
11%

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 7,431 delay minutes reported on OO 6405.

Cancellations run at 3.88%, against 1.81% nationally. That is about one flight in 25 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.

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. 12.2% 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 551 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.

Every one of the 361 flights under OO 6405 in the data flew DFW to SAF. 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. 361 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 6405

For a booking, the cancellation rate is the figure to plan around on OO 6405: 3.88% of its 361 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
