Schedule
When DL 2019 flies

A 09:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 83.9%, and DL 2019 runs 8 points worse at 76.4%. 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
DL 2019 quarter by quarter
DL 2019 did not run the same all year. Its best quarter was Apr–Jun 2026 at 86.8% on time and its weakest Jul–Sep 2026 at 70.5%, a swing of 16 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.

Scale runs 60% to 90%.
By weekday, DL 2019 did best on Tuesday at 86.3% on time and worst on Monday at 65.3%. Each day rests on about 52 flights, so a gap of 21 points is worth noticing but could still narrow in another year.
Arrival by arrival
How late DL 2019 runs when it is late
DL 2019 often beats the schedule: 125 of 356 completed flights, 35%, arrived 15 minutes or more early. The 84 late arrivals split 21 under half an hour, 29 between 30 and 60 minutes, and 34 an hour or more.

Share of 356 completed flights by arrival against schedule.
12 of 68 late departures made up the time and arrived on time, 18% of them. In the other direction, 28 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 2019
The latest arrival of the period was on 2 May 2026, 5 hours 22 minutes behind schedule; most of its delay minutes were filed as national airspace system delay. The five worst days are spread across May, July, November and December, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 2 May 2026 | 5 hours 22 minutes | National Airspace System |
| 11 July 2026 | 5 hours 17 minutes | Late-arriving aircraft |
| 1 November 2025 | 5 hours | Carrier |
| 29 December 2025 | 4 hours 7 minutes | Carrier |
| 14 December 2025 | 4 hours 2 minutes | Extreme weather |
Delay causes
Why DL 2019 runs late
Carrier accounts for 50% of the 5,887 delay minutes carriers reported here, and the remaining four split what is left.

- 35%National Airspace System
- 11%Late-arriving aircraft
- 4%Extreme weather
- 1%Security
35% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 2,040 minutes out of 5,887, against a national NAS share of 21%. The split is drawn from 5,887 delay minutes reported on DL 2019.
Cancellations sit at 2.19% against a national 1.89%, which is ordinary. Diversions add another 0.27%.
Connections and routes
What a delay on this flight costs
9.6% 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 944 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.
The same number turns up on one other city pair in the data, including MCO to JFK (76), but none flew often enough under DL 2019 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to JFK to MCO only.
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 2019
For a booking, read DL 2019 as 76.4% on time with 2.19% cancelled over 365 flights. Those are rates from the past twelve months, not a forecast for any particular day.
