DL 2035 earns a D, which is as low as this site's scale goes for a reason. Only 56.8% of flights arrive inside the 15-minute window, 21 points worse than the national rate of 77.3%. Late arrivals average a little over an hour. Treat any tight connection here as a coin flip. That rests on 351 flights, with a median arrival 7 minutes late.
The national on-time rate over the same period is 77.3%, so DL 2035 runs 21 points behind the country as a whole. Across a thousand flights that is about 205 extra late arrivals.

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 2026 at 37.1%, a swing of 31 points on roughly 88 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 Wednesday at 68.8% on time and worst on Sunday at 40.0%. Each day rests on about 50 flights, so a gap of 29 points is worth noticing but could still narrow in another year.

Share of 345 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 125 departures that left 15 minutes late or more, only 6 made it up before arrival. In the other direction, 30 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 worst days
Worst days for DL 2035
The latest arrival of the period was on 22 May 2026, 6 hours 5 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. On three of the five worst days the largest share was filed as carrier-caused (crew, maintenance, fuelling, baggage).
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 22 May 2026 | 6 hours 5 minutes | Late-arriving aircraft |
| 14 June 2026 | 4 hours 38 minutes | Carrier |
| 6 July 2026 | 4 hours 34 minutes | National Airspace System |

Delay causes
Why DL 2035 runs late
Carrier accounts for 52% of the 11,000 delay minutes carriers reported here, and the remaining four split what is left.
- 52%Carrier
- 27%National Airspace System
- 18%Late-arriving aircraft
- 3%Extreme weather
The largest share of delay minutes, 52%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 5,548 of the 11,000 delay minutes reported here. The split is drawn from 10,710 delay minutes reported on DL 2035.
Cancellations sit at 1.71% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
17.7% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection 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 (150), 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. 351 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. 17.7% 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.
