Historical statistics for July 2025 to June 2026, not live status. For today’s F9 3097, check with Frontier Airlines.
F9 3097 earns an F−, which is as low as this site's scale goes for a reason. Only 51.6% of flights arrive inside the 15-minute window, 26 points worse than the national rate of 77.6%. Late arrivals average a little over an hour. Treat any tight connection here as a coin flip. That rests on 321 flights, with a median arrival 13 minutes late.
The national on-time rate over the same period is 77.6%, so F9 3097 runs 26 points behind the country as a whole. Across a thousand flights that is about 260 extra late arrivals.

These figures cover 321 flights between July 2025 and June 2026. Beyond the headline rate, 23.2% 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 3097 flies
F9 3097 flies ATL to DFW without a single fixed slot. Its most common scheduled departure was 21:15, used on 98 of 321 flights, with 21:00 (40 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 21:15 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and F9 3097 runs 19 points worse at 51.6%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year
F9 3097 quarter by quarter
F9 3097 did not run the same all year. Its best quarter was Oct–Dec 2025 at 60.0% on time and its weakest Jul–Sep 2025 at 45.0%, a swing of 15 points on roughly 80 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.
- Jul–Sep 202564 flights45.0%
- Oct–Dec 202587 flights60.0%
- Jan–Mar 202685 flights47.6%

By weekday, F9 3097 did best on Wednesday at 77.8% on time and worst on Monday at 38.3%. Each day rests on about 46 flights, so a gap of 40 points is worth noticing but could still narrow in another year.
Delay causes
Why F9 3097 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 61% of the 12,000 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.
- 61%Late-arriving aircraft
- 22%Carrier
- 16%National Airspace System
- 1%Extreme weather
61% 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 12,000 reported delay minutes here, that single category outweighs weather by 43 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 11,587 delay minutes reported on F9 3097.
Cancellations run at 3.43%, 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. 23.2% 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 731 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.
Every one of the 321 flights under F9 3097 in the data flew ATL to DFW. 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. 321 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 3097
For a booking, the cancellation rate is the figure to plan around on F9 3097: 3.43% of its 321 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.
