DL 547 lands a B, 2 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 292 flights, with a median arrival 5 minutes early.

These figures cover 292 flights between July 2025 and June 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.

Schedule

When DL 547 flies

DL 547 flies LAX to MCO without a single fixed slot. Its most common scheduled departure was 22:15, used on 37 of 292 flights, with 21:45 (36 flights) and 23:45 (35 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 22:15 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and DL 547 runs 9 points better at 79.8%. 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 547 next to LAX to MCO

Across the year

DL 547 quarter by quarter

DL 547 did not run the same all year. Its best quarter was Jul–Sep 2025 at 90.5% on time and its weakest Jan–Mar 2026 at 68.5%, a swing of 22 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.

Jul–Sep 202564 flights90.5%
Oct–Dec 202562 flights83.9%
Jan–Mar 202675 flights68.5%
Apr–Jun 202691 flights78.7%

Scale runs 60% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, DL 547 ranged from 74.5% on Friday to 83.0% on Thursday. With about 42 flights behind each day, a spread of 9 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 547 runs late

One category carries most of the weight here. Carrier accounts for 54% of the 4,146 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
54%
Late-arriving aircraft
28%
National Airspace System
15%
Extreme weather
3%

The largest share of delay minutes, 54%, 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 2,257 of the 4,146 delay minutes reported here. The split is drawn from 4,146 delay minutes reported on DL 547.

Cancellations sit at 1.71% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

6.6% 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 a little over an hour, which a normal layover absorbs.

At 2,218 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.

Every one of the 292 flights under DL 547 in the data flew LAX to MCO. The number was not reused on any other city pair, which makes this a clean record of one route.

One caution: this is a thin sample. 292 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.
