Time lost at the gate mostly stays lost. Of 100 departures that left 15 minutes late or more, only 11 made it up before arrival. In the other direction, 17 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at DAY.

Delay causes
Why OH 5435 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 11,000 reported delay minutes.
- 41%Late-arriving aircraft
- 37%Carrier
- 11%Extreme weather
- 11%National Airspace System
Extreme weather accounts for 11% 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 1.9 times the usual weather exposure. The split is drawn from 10,980 delay minutes reported on OH 5435.
Cancellations sit at 1.53% against a national 1.89%, which is ordinary. Diversions add another 0.31%.
Connections and routes
What a delay on this flight costs
17.8% 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.
Every one of the 327 flights under OH 5435 in the data flew CLT to DAY. 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. 327 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 OH 5435
For a booking, OH 5435 is a flight to put a long connection behind. 17.8% 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.
