These figures cover 345 flights between July 2025 and June 2026. Beyond the headline rate, 8.7% 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 4797 flies

F9 4797 flies RDU to ATL without a single fixed slot. Its most common scheduled departure was 06:10, used on 79 of 345 flights, with 06:00 (75 flights) and 06:15 (68 flights) next. 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 06:10 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and F9 4797 runs 10 points worse at 79.3%. 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 4797 quarter by quarter

Quarter by quarter F9 4797 held fairly steady: 77.9% in Jul–Sep 2025, 80.0% in Oct–Dec 2025, 76.2% in Jan–Mar 2026 and 82.4% in Apr–Jun 2026. A spread of 6 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, F9 4797 did best on Thursday at 92.0% on time and worst on Sunday at 73.5%. Each day rests on about 49 flights, so a gap of 19 points is worth noticing but could still narrow in another year.

Delay causes

Why F9 4797 runs late

One category carries most of the weight here. Carrier accounts for 44% of the 7,852 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.

The largest share of delay minutes, 44%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 3,432 of the 7,852 delay minutes reported here. The split is drawn from 7,852 delay minutes reported on F9 4797.

Cancellations run at 3.48%, 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

8.7% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last close to two hours, which a normal layover absorbs.

Every one of the 345 flights under F9 4797 in the data flew RDU to ATL. 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. 345 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 4797

For a booking, the cancellation rate is the figure to plan around on F9 4797: 3.48% of its 345 scheduled flights did not operate. A late arrival costs close to two hours, but a cancellation costs the day, so leave a later option open.
