Historical statistics for July 2025 to June 2026, not live status. For today’s OO 6305, 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 6305 draws a C. About one flight in three arrives at least 15 minutes late, and the typical late arrival is an hour and a half behind schedule. Build slack into anything you connect to. That rests on 360 flights, with a median arrival 2 minutes early.
The national on-time rate over the same period is 77.6%, so OO 6305 runs 10 points behind the country as a whole. Across a thousand flights that is about 102 extra late arrivals.

A 19:00 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and OO 6305 runs level with that at 67.4%. 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 6305 quarter by quarter
OO 6305 did not run the same all year. Its best quarter was Oct–Dec 2025 at 73.9% on time and its weakest Jan–Mar 2026 at 59.8%, a swing of 14 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.

By weekday, OO 6305 did best on Wednesday at 77.6% on time and worst on Sunday at 57.7%. Each day rests on about 51 flights, so a gap of 20 points is worth noticing but could still narrow in another year.
Delay causes
Why OO 6305 runs late
One category carries most of the weight here. Carrier accounts for 42% of the 11,000 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.
- 42%Carrier
- 29%Extreme weather
- 21%Late-arriving aircraft
- 8%National Airspace System
Extreme weather accounts for 29% 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 4.6 times the usual weather exposure. The split is drawn from 11,386 delay minutes reported on OO 6305.
Cancellations sit at 2.22% against a national 1.81%, which is ordinary. Diversions add another 0.56%.
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. 18.0% 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 846 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 360 flights under OO 6305 in the data flew DFW to SBN. 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. 360 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 6305
For a booking, OO 6305 is a flight to put a long connection behind. 18.0% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
