Historical statistics for July 2025 to June 2026, not live status. For today’s DL 2035, check with Delta Air Lines.

DL 2035 earns a D, which is as low as this site's scale goes for a reason. Only 56.7% of flights arrive inside the 15-minute window, 21 points worse than the national rate of 77.6%. Late arrivals average about an hour. Treat any tight connection here as a coin flip. That rests on 344 flights, with a median arrival 8 minutes late.

The national on-time rate over the same period is 77.6%, so DL 2035 runs 21 points behind the country as a whole. Across a thousand flights that is about 209 extra late arrivals.

These figures cover 344 flights between July 2025 and June 2026. Beyond the headline rate, 17.5% 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.

Schedule

When DL 2035 flies

DL 2035 flies ATL to MCO without a single fixed slot. Its most common scheduled departure was 18:15, used on 189 of 344 flights, with 18:20 (48 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 18:15 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and DL 2035 runs 12 points worse at 56.7%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Against the route

DL 2035 next to ATL to MCO

Every carrier on ATL to MCO combined arrived on time 70.7% of the time across 8,211 flights, so DL 2035 is 14 points behind it. Delta flew 5,465 flights on the same city pair under all its flight numbers, including this one, and those ran 70.7% on time. Across its whole network Delta Air Lines managed 81.6%, which this flight trails by 25 points.

Across the year

DL 2035 quarter by quarter

DL 2035 did not run the same all year. Its best quarter was Apr–Jun 2026 at 68.1% on time and its weakest Jul–Sep 2025 at 40.0%, a swing of 28 points on roughly 86 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.

Jan–Mar 202689 flights58.8%

Scale runs 30% to 75%. Rows with fewer than 30 flights show a dash.

By weekday, DL 2035 did best on Tuesday at 70.0% on time and worst on Sunday at 38.8%. Each day rests on about 49 flights, so a gap of 31 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 2035 runs late

One category carries most of the weight here. Carrier accounts for 50% of the 9,730 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.

National Airspace System

18%
Extreme weather
2%

The largest share of delay minutes, 50%, 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 4,838 of the 9,730 delay minutes reported here. The split is drawn from 9,730 delay minutes reported on DL 2035.

Cancellations sit at 2.03% 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. 17.5% 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 same number turns up on one other city pair in the data, including MCO to ATL (129), but none flew often enough under DL 2035 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ATL to MCO only.

One caution: this is a thin sample. 344 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 2035

For a booking, DL 2035 is a flight to put a long connection behind. 17.5% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
