Historical statistics for July 2025 to June 2026, not live status. For today’s F9 4702, check with Frontier Airlines.
F9 4702 earns an F−, which is as low as this site's scale goes for a reason. Only 50.6% of flights arrive inside the 15-minute window, 27 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 253 flights, with a median arrival 14 minutes late.
The national on-time rate over the same period is 77.6%, so F9 4702 runs 27 points behind the country as a whole. Across a thousand flights that is about 270 extra late arrivals.

These figures cover 253 flights between July 2025 and June 2026. Beyond the headline rate, 18.5% 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 17:31 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and F9 4702 runs 18 points worse at 50.6%. 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 4702 quarter by quarter
F9 4702 did not run the same all year. Its best quarter was Apr–Jun 2026 at 56.8% on time and its weakest Jul–Sep 2025 at 34.6%, a swing of 22 points on roughly 63 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 202559 flights34.6%
- Oct–Dec 202551 flights52.0%
- Jan–Mar 202661 flights55.0%

Scale runs 25% to 60%. Rows with fewer than 30 flights show a dash.
By weekday, F9 4702 did best on Thursday at 66.7% on time and worst on Sunday at 39.6%. Each day rests on about 36 flights, so a gap of 27 points is worth noticing but could still narrow in another year.
Delay causes
Why F9 4702 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 64% of the 8,741 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.
- 64%Late-arriving aircraft
- 27%National Airspace System
- 6%Carrier
- 4%Extreme weather
64% 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 8,741 reported delay minutes here, that single category outweighs weather by 16 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 8,741 delay minutes reported on F9 4702.
Cancellations run at 3.95%, against 1.81% nationally. That is about one flight in 25 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. 18.5% 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 813 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 253 flights under F9 4702 in the data flew AUS 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. 253 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 4702
For a booking, the cancellation rate is the figure to plan around on F9 4702: 3.95% of its 253 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.
