These figures cover 340 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.

Across the year
DL 2554 quarter by quarter
DL 2554 did not run the same all year. Its best quarter was Jul–Sep 2026 at 90.3% on time and its weakest Jan–Mar 2026 at 80.2%, a swing of 10 points on roughly 85 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 2554 did best on Thursday at 94.0% on time and worst on Saturday at 78.9%. Each day rests on about 49 flights, so a gap of 15 points is worth noticing but could still narrow in another year.

Share of 333 completed flights by arrival against schedule.
12 of 43 late departures made up the time and arrived on time, 28% of them. In the other direction, 17 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at ATL.

- 69%Carrier
- 28%National Airspace System
- 3%Extreme weather
The largest share of delay minutes, 69%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,133 of the 3,085 delay minutes reported here. The split is drawn from 3,085 delay minutes reported on DL 2554.
Cancellations sit at 2.06% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 4.2% 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.
Every one of the 340 flights under DL 2554 in the data flew BDL 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. 340 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 2554
For a booking, read DL 2554 as 85.6% on time with 2.06% cancelled over 340 flights. Those are rates from the past twelve months, not a forecast for any particular day.
