These figures cover 365 flights between September 2025 and August 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.

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 90.1%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Delay causes

Why DL 2429 runs late

Carrier accounts for 52% of the 4,143 delay minutes carriers reported here, and the remaining four split what is left.

Carrier

Extreme weather
28%
Late-arriving aircraft
10%
National Airspace System
10%

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 4.6 times the usual weather exposure. The split is drawn from 4,143 delay minutes reported on DL 2429.

Cancellations sit at 1.92% against a national 1.89%, 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 2.3% 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.

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.

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 90.1% on time with 1.92% cancelled over 365 flights. Those are rates from the past twelve months, not a forecast for any particular day.
