These figures cover 255 flights between July 2025 and June 2026. Beyond the headline rate, 11.7% 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 F9 3782 flies

F9 3782 flies ATL to TPA without a single fixed slot. Its most common scheduled departure was 10:03, used on 27 of 255 flights. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 10:03 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and F9 3782 runs 14 points worse at 70.0%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

F9 3782 quarter by quarter

F9 3782 did not run the same all year. Its best quarter was Jan–Mar 2026 at 75.4% on time and its weakest Apr–Jun 2026 at 62.3%, a swing of 13 points on roughly 64 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

By weekday, F9 3782 did best on Thursday at 75.0% on time and worst on Friday at 58.5%. Each day rests on about 36 flights, so a gap of 17 points is worth noticing but could still narrow in another year.

Delay causes

Why F9 3782 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 45% of the 5,073 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.

Late-arriving aircraft
45%
Carrier
38%
National Airspace System
17%

45% 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 5,073 reported delay minutes here, that single category outweighs weather by 45 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 5,073 delay minutes reported on F9 3782.

Cancellations run at 3.14%, against 1.81% nationally. That is about one flight in 30 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. 11.7% 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 255 flights under F9 3782 in the data flew ATL to TPA. 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. 255 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 F9 3782

For a booking, the cancellation rate is the figure to plan around on F9 3782: 3.14% of its 255 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
