Historical statistics for July 2025 to June 2026, not live status. For today’s DL 2554, check with Delta Air Lines.

DL 2554 earns an A. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 8 points better than the national rate of 77.6%. When something does go wrong the average delay runs about an hour. That rests on 329 flights, with a median arrival 9 minutes early.

Set against the rest of the country, DL 2554's record is 8 points better than the US average of 77.6%. That gap is worth roughly 81 fewer late arrivals for every thousand flights.

These figures cover 329 flights between July 2025 and June 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.

Schedule

When DL 2554 flies

DL 2554 flies BDL to ATL without a single fixed slot. Its most common scheduled departure was 07:00, used on 139 of 329 flights, with 07:05 (70 flights) and 07:20 (38 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 07:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 2554 runs 4 points worse at 85.7%. 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 2554 quarter by quarter

DL 2554 did not run the same all year. Its best quarter was Jul–Sep 2025 at 93.4% on time and its weakest Jan–Mar 2026 at 80.2%, a swing of 13 points on roughly 82 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 Monday at 77.8%. Each day rests on about 47 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 2554 runs late

One category carries most of the weight here. Carrier accounts for 71% of the 3,090 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.

  • Carrier
    71%
  • National Airspace System
    26%
  • Extreme weather
    3%

The largest share of delay minutes, 71%, 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 2,184 of the 3,090 delay minutes reported here. The split is drawn from 3,090 delay minutes reported on DL 2554.

Cancellations sit at 2.43% against a national 1.81%, 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 4.4% 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 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. 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 329 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. 329 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 85.7% on time with 2.43% cancelled over 329 flights. Those are rates from the past twelve months, not a forecast for any particular day.
