These figures cover 364 flights between July 2025 and June 2026. The median arrival is 4 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.
Schedule
When F9 2633 flies
F9 2633 flies BWI to ATL without a single fixed slot. Its most common scheduled departure was 06:05, used on 49 of 364 flights, with 06:00 (45 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 06:05 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and F9 2633 runs 15 points worse at 74.7%. 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 2633 quarter by quarter
F9 2633 did not run the same all year. Its best quarter was Oct–Dec 2025 at 81.1% on time and its weakest Jul–Sep 2025 at 71.1%, a swing of 10 points on roughly 91 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 2633 did best on Tuesday at 84.3% on time and worst on Saturday at 57.7%. Each day rests on about 52 flights, so a gap of 27 points is worth noticing but could still narrow in another year.
Delay causes
Why F9 2633 runs late
One category carries most of the weight here. National Airspace System accounts for 49% of the 5,752 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.
- 49%National Airspace System
- 39%Carrier
- 10%Late-arriving aircraft
- 2%Extreme weather
The largest share of delay minutes, 39%, 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 2,247 of the 5,752 delay minutes reported here. The split is drawn from 5,752 delay minutes reported on F9 2633.
Cancellations sit at 2.20% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
6.7% 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 about an hour, which a normal layover absorbs.
The 577 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 364 flights under F9 2633 in the data flew BWI 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. 364 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.
