Schedule
When F9 2428 flies
F9 2428 flies LAS to ATL without a single fixed slot. Its most common scheduled departure was 23:59, used on 63 of 317 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 23:59 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and F9 2428 runs level with that at 71.6%. 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 2428 quarter by quarter
F9 2428 did not run the same all year. Its best quarter was Oct–Dec 2025 at 76.9% on time and its weakest Jul–Sep 2025 at 64.8%, a swing of 12 points on roughly 79 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 202558 flights64.8%
- Oct–Dec 202578 flights76.9%
- Jan–Mar 202690 flights75.0%

By weekday, F9 2428 did best on Wednesday at 83.3% on time and worst on Sunday at 58.8%. Each day rests on about 45 flights, so a gap of 25 points is worth noticing but could still narrow in another year.
Delay causes
Why F9 2428 runs late
One category carries most of the weight here. Carrier accounts for 46% of the 6,311 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.
- 46%Carrier
- 41%Late-arriving aircraft
- 11%National Airspace System
- 3%Extreme weather
41% 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 6,311 reported delay minutes here, that single category outweighs weather by 14 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 6,311 delay minutes reported on F9 2428.
Cancellations sit at 2.21% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
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. 11.3% 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.
At 1,747 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.
Every one of the 317 flights under F9 2428 in the data flew LAS 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. 317 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.
