DL 532 lands a B−, 5 points better than the national rate of 77.3%. About one flight in six arrives 15 minutes late or worse, and those flights are late by about 55 minutes on average. That rests on 255 flights, with a median arrival 10 minutes early.

Set against the rest of the country, DL 532's record is 5 points better than the US average of 77.3%. That gap is worth roughly 51 fewer late arrivals for every thousand flights.

These figures cover 255 flights between September 2025 and August 2026. The median arrival is 10 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 532 flies

DL 532 flies JFK to DEN without a single fixed slot. Its most common scheduled departure was 08:30, used on 55 of 255 flights, with 08:00 (36 flights) and 08:45 (36 flights) next.

Departs 08:3055 flights21.6%

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 08:30 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 83.9%, and DL 532 runs level with that at 82.4%. 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 532 quarter by quarter

DL 532 did not run the same all year. Its best quarter was Apr–Jun 2026 at 90.0% on time and its weakest Jan–Mar 2026 at 77.6%, a swing of 12 points on roughly 85 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 70% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, DL 532 did best on Thursday at 88.9% on time and worst on Saturday at 73.5%. Each day rests on about 36 flights, so a gap of 15 points is worth noticing but could still narrow in another year.

Arrival by arrival

How late DL 532 runs when it is late

DL 532 often beats the schedule: 103 of 244 completed flights, 42%, arrived 15 minutes or more early. Most of the lateness is short. 22 of the 43 late arrivals were under half an hour behind, and 11 reached an hour or more.

Share of 244 completed flights by arrival against schedule.

4 of 21 late departures made up the time and arrived on time, 19% of them. In the other direction, 26 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 DEN.

The worst days

Worst days for DL 532

The latest arrival of the period was on 3 August 2026, 4 hours 28 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on four of the five worst days.

Delay causes

Why DL 532 runs late

National Airspace System accounts for 46% of the 2,339 delay minutes carriers reported here, and the remaining four split what is left.

National Airspace System
46%
Carrier
42%
Extreme weather
6%
Late-arriving aircraft
5%

46% 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 1,087 minutes out of 2,339, against a national NAS share of 21%. The split is drawn from 2,339 delay minutes reported on DL 532.

Cancellations run at 4.31%, against 1.89% nationally. That is about one flight in 25 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 4.5% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

At 1,626 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.

DL 532 is not only a JFK to DEN flight. It also flew DEN to JFK (255 flights, 82.2% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.

One caution: this is a thin sample. 255 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 532
