Connections and routes
What a delay on this flight costs
7.2% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last an hour and a half, which a normal layover absorbs.
The same number turns up on one other city pair in the data, including SBN to ORD (20), but none flew often enough under OO 5649 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LNK to DEN only.
One caution: this is a thin sample. 339 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 5649
For a booking, OO 5649 has one of the better records a US domestic flight can show: 85.6% on time and 1.47% cancelled. That is a base rate, not a promise about any single day.
