Historical statistics for July 2025 to June 2026, not live status. For today’s DL 1054, check with Delta Air Lines.

DL 1054 earns an A−. Nearly every flight arrives inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 16 points better than the national rate of 77.6%. When something does go wrong the average delay runs a little over an hour. That rests on 347 flights, with a median arrival 17 minutes early.

Set against the rest of the country, DL 1054's record is 16 points better than the US average of 77.6%. That gap is worth roughly 155 fewer late arrivals for every thousand flights.

These figures cover 347 flights between July 2025 and June 2026. The median arrival is 17 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 1054 flies

DL 1054 flies RDU to BOS without a single fixed slot. Its most common scheduled departure was 07:00, used on 205 of 347 flights, with 06:45 (48 flights) and 06:40 (35 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 1054 runs 4 points better at 93.1%. 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 1054 next to RDU to BOS

Every carrier on RDU to BOS combined arrived on time 78.8% of the time across 2,815 flights, so DL 1054 is 14 points ahead of it. Delta flew 1,436 flights on the same city pair under all its flight numbers, including this one, and those ran 80.4% on time. Across its whole network Delta Air Lines managed 81.6%, which this flight beats by 12 points.

Across the year

DL 1054 quarter by quarter

DL 1054 did not run the same all year. Its best quarter was Apr–Jun 2026 at 98.9% on time and its weakest Jan–Mar 2026 at 88.5%, a swing of 10 points on roughly 87 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.

Jul–Sep 202591 flights95.5%
Oct–Dec 202580 flights88.6%
Jan–Mar 202685 flights88.5%

Scale runs 80% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, DL 1054 ranged from 89.6% on Friday to 97.9% on Thursday. With about 50 flights behind each day, a spread of 8 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 1054 runs late

One category carries most of the weight here. Carrier accounts for 76% of the 1,573 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
76%
National Airspace System
20%
Extreme weather
4%

The largest share of delay minutes, 76%, 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 1,191 of the 1,573 delay minutes reported here. The split is drawn from 1,573 delay minutes reported on DL 1054.

Cancellations run at 4.03%, against 1.81% nationally. That is about one flight in 25 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 2.4% 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 612 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.

The same number turns up on three other city pairs in the data, including DTW to MCI (16), SNA to SEA (1) and SEA to SNA (1), but none flew often enough under DL 1054 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to RDU to BOS only.

One caution: this is a thin sample. 347 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 1054

For a booking, the cancellation rate is the figure to plan around on DL 1054: 4.03% of its 347 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
