These figures cover 348 flights between September 2025 and August 2026. The median arrival is 16 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 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 3 points better at 92.5%. 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 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.

By weekday, DL 1054 did best on Wednesday at 98.0% on time and worst on Saturday at 83.7%. Each day rests on about 50 flights, so a gap of 14 points is worth noticing but could still narrow in another year.

The latest arrival of the period was on 3 April 2026, 6 hours 37 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 3 April 2026 | 6 hours 37 minutes | Carrier |
| 3 August 2026 | 3 hours 32 minutes | National Airspace System |
| 15 November 2025 | 2 hours 41 minutes | Carrier |

Delay causes
Why DL 1054 runs late
Carrier accounts for 74% of the 1,941 delay minutes carriers reported here, and the remaining four split what is left.
- 74%Carrier
- 26%National Airspace System
The largest share of delay minutes, 74%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,431 of the 1,941 delay minutes reported here. The split is drawn from 1,941 delay minutes reported on DL 1054.
Cancellations run at 4.02%, against 1.89% 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 3.0% 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 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.
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. 348 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: 4.02% of its 348 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.
