DL 3133 lands a B, 6 points better than the national rate of 77.6%. About one flight in six 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 277 flights, with a median arrival 10 minutes early.

Set against the rest of the country, DL 3133's record is 6 points better than the US average of 77.6%. That gap is worth roughly 55 fewer late arrivals for every thousand flights.

These figures cover 277 flights between July 2025 and June 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 3133 flies

DL 3133 flies ATL to GNV without a single fixed slot. Its most common scheduled departure was 13:46, used on 66 of 277 flights, with 14:59 (52 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 13:46 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and DL 3133 runs 4 points better at 83.1%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

DL 3133 quarter by quarter

DL 3133 did not run the same all year. Its best quarter was Apr–Jun 2026 at 87.8% on time and its weakest Jul–Sep 2025 at 77.0%, a swing of 11 points on roughly 69 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 3133 did best on Thursday at 94.9% on time and worst on Saturday at 71.4%. Each day rests on about 40 flights, so a gap of 24 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 3133 runs late

One category carries most of the weight here. Carrier accounts for 58% of the 2,702 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.

Late-arriving aircraft
33%
National Airspace System

Extreme weather
1%

The largest share of delay minutes, 58%, 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 1,566 of the 2,702 delay minutes reported here. The split is drawn from 2,702 delay minutes reported on DL 3133.

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

Connections and routes

What a delay on this flight costs

5.9% 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.

DL 3133 is not only a ATL to GNV flight. It also flew GNV to ATL (277 flights, 84.9% 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. 277 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.
