These figures cover 269 flights between September 2025 and August 2026. The median arrival is 7 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.

Across the year
DL 822 quarter by quarter
DL 822 did not run the same all year. Its best quarter was Jul–Sep 2025 at 96.7% on time and its weakest Apr–Jun 2026 at 83.9%, a swing of 13 points on roughly 67 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.

By weekday, DL 822 did best on Tuesday at 97.3% on time and worst on Sunday at 81.6%. Each day rests on about 38 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Delay causes
Why DL 822 runs late
Late-arriving aircraft accounts for 56% of the 1,272 delay minutes carriers reported here, and the remaining four split what is left.
- 56%Late-arriving aircraft
- 31%Carrier
- 14%National Airspace System
56% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 1,272 reported delay minutes here, that single category outweighs weather by 56 to one. The split is drawn from 1,272 delay minutes reported on DL 822.
Cancellations sit at 1.12% against a national 1.89%, 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 1.5% 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 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 three other city pairs in the data, including BNA to LGA (46), MCO to LGA (5) and ATL to DCA (1), 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. 269 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: 88.7% on time and 1.12% cancelled. That is a base rate, not a promise about any single day.
