Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with SkyWest Airlines.
SkyWest on DFW to FSD sits in the middle of the pack with a B−. Close to three flights in four arrive on time by the DOT's definition, 3 points worse than the national rate of 77.6%. The late ones land close to two hours behind schedule. That rests on 125 flights, with a median arrival 4 minutes early.
The US average over the same twelve months is 77.6%, so there is little to separate SkyWest on DFW to FSD from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Every carrier on DFW to FSD, 1,086 flights
These figures cover 125 flights between July 2025 and June 2026. The median arrival is 4 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.
Carrier by carrier
SkyWest against every carrier on DFW to FSD
SkyWest flew 125 of the 1,086 flights on DFW to FSD, about 12% of it. Its 75.0% on time is 9 points better than the route as a whole, which runs 66.5%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from Envoy at 86.1% to American at 56.1%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

Departure window
When SkyWest runs best on this route
Departure time is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 125 flights.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 75.0% on time across 125 flights.
Split by quarter, SkyWest on DFW to FSD logged 38 flights in Jul–Sep 2025, 7 flights in Oct–Dec 2025, 1 flights in Jan–Mar 2026 and 79 flights in Apr–Jun 2026. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 75.0% annual figure is the one to use.
Delay causes
Why SkyWest runs late on this route
One category carries most of the weight here. Carrier accounts for 60% of the 3,014 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.
- 60%Carrier
- 19%Extreme weather
- 16%Late-arriving aircraft
- 5%National Airspace System
Extreme weather accounts for 19% 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 monthly strip above is the more useful view of the risk. The national share is 6%, so this operation carries roughly 3.0 times the usual weather exposure. The split is drawn from 3,014 reported delay minutes.
The largest share of delay minutes, 60%, 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 1,814 of the 3,014 delay minutes reported here.
Cancellations run at 4.00%, 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 stage length
What a delay here 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 close to two hours, which a normal layover absorbs.
The 737 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 return leg is a different operation and performs like one: it runs 69.7% on time across 125 flights, 5 points below this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 5 points of difference.
One caution: this is a thin sample. 125 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 SkyWest on DFW to FSD
Put together: the delay figures matter less here than the 4.00% cancellation rate. A late arrival costs you close to two hours; a cancelled flight costs you the day. Book the 2pm–5pm departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 120 completed flights over 12 months sit behind that.
