Historical statistics for July 2025 to June 2026, not live status. For today’s OH 5115, check with PSA Airlines. PSA Airlines flies under contract for larger airlines, so a ticket for this flight may show a different airline code and number.
OH 5115 sits in the middle of the pack with a C. About seven flights in ten arrive on time by the DOT's definition, 7 points worse than the national rate of 77.6%. The late ones land a little over an hour behind schedule. That rests on 269 flights, with a median arrival 5 minutes early.

These figures cover 269 flights between July 2025 and June 2026. Beyond the headline rate, 11.9% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 17:56 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and OH 5115 runs 2 points better at 70.5%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Delay causes
Why OH 5115 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 44% of the 5,804 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.
- 44%Late-arriving aircraft
- 37%National Airspace System
- 15%Carrier
- 4%Extreme weather
44% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 5,804 reported delay minutes here, that single category outweighs weather by 10 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 5,804 delay minutes reported on OH 5115.
Cancellations sit at 2.23% against a national 1.81%, which is ordinary. Diversions add another 0.74%.
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. 11.9% 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 861 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.
The same number turns up on three other city pairs in the data, including DFW to DAY (44), CHA to DFW (41) and DFW to CHA (41), but none flew often enough under OH 5115 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DAY to DFW only.
One caution: this is a thin sample. 269 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
