These figures cover 365 flights between July 2025 and June 2026. The median arrival is 8 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.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 22:16 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and DL 2435 runs 11 points better at 81.3%. 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
DL 2435 quarter by quarter
DL 2435 did not run the same all year. Its best quarter was Oct–Dec 2025 at 86.7% on time and its weakest Jul–Sep 2025 at 74.4%, a swing of 12 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.
- Jul–Sep 202592 flights74.4%
- Oct–Dec 202592 flights86.7%
- Jan–Mar 202690 flights80.9%
- Apr–Jun 202691 flights83.3%
Scale runs 65% to 90%. Rows with fewer than 30 flights show a dash.
By weekday, DL 2435 did best on Wednesday at 86.5% on time and worst on Friday at 73.1%. Each day rests on about 52 flights, so a gap of 13 points is worth noticing but could still narrow in another year.
Delay causes
Why DL 2435 runs late
One category carries most of the weight here. Carrier accounts for 66% of the 5,464 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.
- 66%Carrier
- 24%Late-arriving aircraft
- 7%National Airspace System
- 3%Extreme weather
The largest share of delay minutes, 66%, 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 3,620 of the 5,464 delay minutes reported here. The split is drawn from 5,464 delay minutes reported on DL 2435.
Cancellations sit at 1.64% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
6.1% 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 a little over an hour, which a normal layover absorbs.
Every one of the 365 flights under DL 2435 in the data flew ATL to MLB. 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. 365 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 DL 2435
