DL 2818 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 13 points better than the national rate of 77.6%. When something does go wrong the average delay runs about 2.3 hours. That rests on 303 flights, with a median arrival 18 minutes early.

Set against the rest of the country, DL 2818's record is 13 points better than the US average of 77.6%. That gap is worth roughly 126 fewer late arrivals for every thousand flights.

These figures cover 303 flights between July 2025 and June 2026. The median arrival is 18 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 2818 flies

DL 2818 is scheduled to leave Roanoke (ROA) at 06:00 local time and reach Atlanta (ATL) at 07:41. That slot held for 300 of the 303 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

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

A 06:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 2818 runs level with that at 90.2%. 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 2818 next to ROA to ATL

Across the year

DL 2818 quarter by quarter

Quarter by quarter DL 2818 held fairly steady: 90.0% in Jul–Sep 2025, 86.7% in Oct–Dec 2025, 93.0% in Jan–Mar 2026 and 91.0% in Apr–Jun 2026. A spread of 6 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202530 flights90.0%
Oct–Dec 202592 flights86.7%

Scale runs 80% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, DL 2818 did best on Friday at 95.3% on time and worst on Thursday at 76.7%. Each day rests on about 43 flights, so a gap of 19 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 2818 runs late

One category carries most of the weight here. Carrier accounts for 89% of the 3,940 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
89%
National Airspace System
11%

The largest share of delay minutes, 89%, 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 3,500 of the 3,940 delay minutes reported here. The split is drawn from 3,940 delay minutes reported on DL 2818.

Cancellations run at 2.64%, against 1.81% nationally. That is about one flight in 40 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 4.4% 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.

The same number turns up on one other city pair in the data, including ATL to MEM (6), but none flew often enough under DL 2818 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ROA to ATL only.

One caution: this is a thin sample. 303 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 2818

For a booking, the cancellation rate is the figure to plan around on DL 2818: 2.64% of its 303 scheduled flights did not operate. A late arrival costs about 2.3 hours, but a cancellation costs the day, so leave a later option open.
