These figures cover 349 flights between September 2025 and August 2026. The median arrival is 9 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 2933 runs level with that at 90.0%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year
DL 2933 quarter by 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.

- 70%Carrier
- 27%National Airspace System
- 3%Extreme weather
The largest share of delay minutes, 70%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 958 of the 1,369 delay minutes reported here. The split is drawn from 1,369 delay minutes reported on DL 2933.
Cancellations sit at 1.72% against a national 1.89%, which is ordinary. Diversions add another 0.86%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 1.5% 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 859 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.
The same number turns up on two other city pairs in the data, including MSY to DTW (14) and DTW to MSY (14), but none flew often enough under DL 2933 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to BDL to ATL only.
One caution: this is a thin sample. 349 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 2933
For a booking, read DL 2933 as 90.0% on time with 1.72% cancelled over 349 flights. Those are rates from the past twelve months, not a forecast for any particular day.
