These figures cover 326 flights between July 2025 and June 2026. Beyond the headline rate, 12.1% 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.

Schedule

When OO 6313 flies

OO 6313 flies DFW to BPT without a single fixed slot. Its most common scheduled departure was 21:25, used on 99 of 326 flights, with 21:30 (67 flights) and 21:37 (42 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

A 21:25 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and OO 6313 runs 5 points better at 75.9%. 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 OO 6313 runs late

One category carries most of the weight here. Carrier accounts for 46% of the 13,000 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.

Carrier
46%
Extreme weather
40%
Late-arriving aircraft
12%
National Airspace System
2%

Extreme weather accounts for 40% 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 6.4 times the usual weather exposure. The split is drawn from 13,455 delay minutes reported on OO 6313.

Cancellations run at 4.91%, against 1.81% nationally. That is about one flight in twenty cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.

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. 12.1% 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.

Every one of the 326 flights under OO 6313 in the data flew DFW to BPT. 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. 326 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 6313

For a booking, the cancellation rate is the figure to plan around on OO 6313: 4.91% of its 326 scheduled flights did not operate. A late arrival costs about 3.0 hours, but a cancellation costs the day, so leave a later option open.
