Period: July 2025 to June 2026

Historical statistics for July 2025 to June 2026, not live status. For today’s OO 6403, 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 6403 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 2.2 hours on average. That is a workable record, not a spotless one. That rests on 282 flights, with a median arrival 11 minutes early.

Set against the rest of the country, OO 6403's record is 6 points better than the US average of 77.6%. That gap is worth roughly 60 fewer late arrivals for every thousand flights.

These figures cover 282 flights between July 2025 and June 2026. Beyond the headline rate, 9.5% 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 6403 flies

OO 6403 is scheduled to leave Santa Fe (SAF) at 06:15 local time and reach Dallas-Fort Worth (DFW) at 09:09. That slot held for 241 of the 282 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 06:15 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and OO 6403 runs 6 points worse at 83.6%. 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 6403 quarter by quarter

OO 6403 did not run the same all year. Its best quarter was Jul–Sep 2025 at 87.8% on time and its weakest Apr–Jun 2026 at 77.5%, a swing of 10 points on roughly 71 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 flights87.8%
Oct–Dec 202546 flights87.0%
Jan–Mar 202653 flights83.7%

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

By weekday, OO 6403 did best on Thursday at 95.0% on time and worst on Tuesday at 76.3%. Each day rests on about 40 flights, so a gap of 19 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 6403 runs late

One category carries most of the weight here. Carrier accounts for 59% of the 5,915 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.

Late-arriving aircraft
23%
Extreme weather
11%
National Airspace System
7%

The largest share of delay minutes, 59%, 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 3,491 of the 5,915 delay minutes reported here. The split is drawn from 5,915 delay minutes reported on OO 6403.

Cancellations sit at 2.48% against a national 1.81%, which is ordinary. Diversions add another 0.35%.

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. 9.5% 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.

The same number turns up on one other city pair in the data, including DFW to SHV (18), but none flew often enough under OO 6403 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SAF to DFW only.

One caution: this is a thin sample. 282 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.
