Delay causes
Why OO 6305 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 12,000 reported delay minutes.
- 38%Carrier
- 34%Extreme weather
- 20%Late-arriving aircraft
- 8%National Airspace System
Extreme weather accounts for 34% 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 5.6 times the usual weather exposure. The split is drawn from 12,248 delay minutes reported on OO 6305.
Cancellations sit at 1.67% against a national 1.89%, which is ordinary. Diversions add another 0.56%.
Connections and routes
What a delay on this flight costs
17.9% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection 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.
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. 17.9% 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.
