Historical statistics for July 2025 to June 2026, not live status. For today’s DL 2019, check with Delta Air Lines.

DL 2019 lands a B, level with the national rate of 77.6%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 365 flights, with a median arrival 9 minutes early.

These figures cover 365 flights between July 2025 and June 2026. The median arrival is 9 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.

Schedule

When DL 2019 flies

DL 2019 flies JFK to MCO without a single fixed slot. Its most common scheduled departure was 09:00, used on 156 of 365 flights, with 09:53 (66 flights) and 09:50 (65 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 09:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and DL 2019 runs 6 points worse at 78.1%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Against the route

DL 2019 next to JFK to MCO

Every carrier on JFK to MCO combined arrived on time 73.7% of the time across 4,887 flights, so DL 2019 is 4 points ahead of it. Delta flew 1,979 flights on the same city pair under all its flight numbers, including this one, and those ran 77.6% on time. Across its whole network Delta Air Lines managed 81.6%, which this flight trails by 4 points.

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 Jan–Mar 2026 at 71.1%, a swing of 16 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 flights82.4%
Oct–Dec 202592 flights71.4%
Jan–Mar 202690 flights71.1%
Apr–Jun 202691 flights86.8%

Scale runs 65% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, DL 2019 did best on Tuesday at 86.5% on time and worst on Saturday at 67.3%. Each day rests on about 52 flights, so a gap of 19 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 2019 runs late

One category carries most of the weight here. Carrier accounts for 55% of the 5,051 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.

Carrier
55%
National Airspace System
34%

Extreme weather

Security
1%

34% 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 1,696 minutes out of 5,051, against a national NAS share of 21%. The split is drawn from 5,051 delay minutes reported on DL 2019.

Cancellations sit at 2.19% against a national 1.81%, which is ordinary. Diversions add another 0.27%.

Connections and routes

What a delay on this flight costs

7.9% 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 about an hour, which a normal layover absorbs.

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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

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 78.1% on time with 2.19% cancelled over 365 flights. Those are rates from the past twelve months, not a forecast for any particular day.
