These figures cover 365 flights between September 2025 and August 2026. The median arrival is 5 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.

Across the year
DL 1030 quarter by quarter
DL 1030 did not run the same all year. Its best quarter was Apr–Jun 2026 at 85.6% on time and its weakest Oct–Dec 2025 at 75.0%, a swing of 11 points on roughly 73 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, DL 1030 did best on Thursday at 88.2% on time and worst on Saturday at 70.0%. Each day rests on about 52 flights, so a gap of 18 points is worth noticing but could still narrow in another year.

Share of 358 completed flights by arrival against schedule.
9 of 62 late departures made up the time and arrived on time, 15% of them. In the other direction, 18 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at MCO.

The largest share of delay minutes, 47%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,016 of the 4,246 delay minutes reported here. The split is drawn from 4,246 delay minutes reported on DL 1030.

Connections and routes
What a delay on this flight costs
5.6% of arrivals land an hour or more late, close to the national 8.3%, so 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.
DL 1030 is not only a ATL to MCO flight. It also flew MCO to ATL (358 flights, 73.0% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.
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.
