Historical statistics for July 2025 to June 2026, not live status. For today’s DL 822, check with Delta Air Lines.

DL 822 earns an A+. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 12 points better than the national rate of 77.6%. When something does go wrong the average delay runs about 40 minutes. That rests on 330 flights, with a median arrival 8 minutes early.

Set against the rest of the country, DL 822's record is 12 points better than the US average of 77.6%. That gap is worth roughly 117 fewer late arrivals for every thousand flights.

These figures cover 330 flights between July 2025 and June 2026. The median arrival is 8 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 822 flies

DL 822 flies LAS to RDU without a single fixed slot. Its most common scheduled departure was 22:59, used on 40 of 330 flights, with 22:24 (38 flights) and 22:30 (38 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 22:59 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and DL 822 runs 19 points better at 89.3%. 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 822 next to LAS to RDU

Across the year

DL 822 quarter by quarter

Quarter by quarter DL 822 held fairly steady: 93.4% in Jul–Sep 2025, 88.5% in Oct–Dec 2025, 89.7% in Jan–Mar 2026 and 83.9% in Apr–Jun 2026. A spread of 10 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Oct–Dec 202587 flights88.5%
Jan–Mar 202690 flights89.7%

Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, DL 822 did best on Tuesday at 95.7% on time and worst on Sunday at 80.9%. Each day rests on about 47 flights, so a gap of 15 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 822 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 51% of the 1,410 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.

51%

31%
National Airspace System
18%

51% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 1,410 reported delay minutes here, that single category outweighs weather by 51 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 1,410 delay minutes reported on DL 822.

Cancellations sit at 0.91% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 1.2% land an hour or more behind schedule, against 8.1% 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 2,026 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.

The same number turns up on one other city pair in the data, including MCO to LGA (5), but none flew often enough under DL 822 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LAS to RDU only.

One caution: this is a thin sample. 330 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 822

For a booking, DL 822 has one of the better records a US domestic flight can show: 89.3% on time and 0.91% cancelled. That is a base rate, not a promise about any single day.
