Schedule
When OO 6335 flies
OO 6335 flies SBN to DFW without a single fixed slot. Its most common scheduled departure was 07:25, used on 62 of 365 flights, with 07:11 (50 flights) and 07:22 (43 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 07:25 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and OO 6335 runs 15 points worse at 73.9%. 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 6335 quarter by quarter
OO 6335 did not run the same all year. Its best quarter was Jul–Sep 2025 at 82.0% on time and its weakest Oct–Dec 2025 at 67.4%, a swing of 15 points on roughly 91 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 flights82.0%
- Oct–Dec 202592 flights67.4%
- Jan–Mar 202690 flights70.9%

By weekday, OO 6335 did best on Wednesday at 84.0% on time and worst on Saturday at 65.3%. Each day rests on about 52 flights, so a gap of 19 points is worth noticing but could still narrow in another year.
Delay causes
Why OO 6335 runs late
One category carries most of the weight here. Carrier accounts for 49% of the 9,874 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.
- 49%Carrier
- 26%Extreme weather
- 16%Late-arriving aircraft
- 9%National Airspace System
- 0%Security
Extreme weather accounts for 26% 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 4.2 times the usual weather exposure. The split is drawn from 9,874 delay minutes reported on OO 6335.
Cancellations sit at 1.64% against a national 1.81%, which is ordinary. Diversions add another 0.82%.
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. 10.1% 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 365 flights under OO 6335 in the data flew SBN to DFW. 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. 365 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.
