DL 2429 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 close to two hours. That rests on 365 flights, with a median arrival 12 minutes early.

Set against the rest of the country, DL 2429's record is 12 points better than the US average of 77.6%. That gap is worth roughly 119 fewer late arrivals for every thousand flights.

These figures cover 365 flights between July 2025 and June 2026. The median arrival is 12 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 2429 flies

DL 2429 flies ALB to ATL without a single fixed slot. Its most common scheduled departure was 06:00, used on 165 of 365 flights, with 06:10 (102 flights) and 06:07 (43 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 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 2429 runs level with that at 89.5%. 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 2429 next to ALB to ATL

Across the year

DL 2429 quarter by quarter

DL 2429 did not run the same all year. Its best quarter was Apr–Jun 2026 at 95.5% on time and its weakest Jan–Mar 2026 at 85.1%, a swing of 10 points on roughly 91 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.

Jan–Mar 202690 flights85.1%

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

By weekday, DL 2429 ranged from 84.3% on Saturday to 94.2% on Wednesday. With about 52 flights behind each day, a spread of 10 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 2429 runs late

One category carries most of the weight here. Carrier accounts for 42% of the 4,085 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.

42%
Extreme weather
28%
Late-arriving aircraft
18%
National Airspace System
11%

Extreme weather accounts for 28% 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 4.5 times the usual weather exposure. The split is drawn from 4,085 delay minutes reported on DL 2429.

Cancellations sit at 2.19% against a national 1.81%, which is ordinary. Diversions add another 0.82%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 2.5% 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 853 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 365 flights under DL 2429 in the data flew ALB to ATL. 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. 365 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 2429

For a booking, read DL 2429 as 89.5% on time with 2.19% cancelled over 365 flights. Those are rates from the past twelve months, not a forecast for any particular day.
