DL 2945 lands a B, level with the national rate of 77.6%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 364 flights, with a median arrival 4 minutes early.

These figures cover 364 flights between July 2025 and June 2026. The median arrival is 4 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 2945 flies

DL 2945 flies ATL to ATW without a single fixed slot. Its most common scheduled departure was 20:35, used on 61 of 364 flights, with 21:35 (50 flights) and 20:25 (48 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

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

A 20:35 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and DL 2945 runs 8 points better at 78.1%. 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 2945 next to ATL to ATW

Every carrier on ATL to ATW combined arrived on time 78.3% of the time across 368 flights, so DL 2945 is about level with it. Across its whole network Delta Air Lines managed 81.6%, which this flight trails by 4 points.

Across the year

DL 2945 quarter by quarter

Quarter by quarter DL 2945 held fairly steady: 72.8% in Jul–Sep 2025, 81.6% in Oct–Dec 2025, 75.6% in Jan–Mar 2026 and 82.4% 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.

Jul–Sep 202592 flights72.8%
Oct–Dec 202591 flights81.6%

Scale runs 65% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, DL 2945 did best on Wednesday at 86.5% on time and worst on Sunday at 71.4%. Each day rests on about 52 flights, so a gap of 15 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 2945 runs late

One category carries most of the weight here. Carrier accounts for 48% of the 5,032 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
48%
Late-arriving aircraft
23%
Extreme weather
16%
National Airspace System
13%

Extreme weather accounts for 16% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.5 times the usual weather exposure. The split is drawn from 5,032 delay minutes reported on DL 2945.

Cancellations sit at 1.65% against a national 1.81%, which is ordinary. Diversions add another 0.55%.

Connections and routes

What a delay on this flight costs

6.5% 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 about an hour, which a normal layover absorbs.

The 765 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

Every one of the 364 flights under DL 2945 in the data flew ATL to ATW. 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. 364 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 2945

For a booking, read DL 2945 as 78.1% on time with 1.65% cancelled over 364 flights. Those are rates from the past twelve months, not a forecast for any particular day.
