These figures cover 365 flights between July 2025 and June 2026. The median arrival is 15 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 2601 flies

DL 2601 flies BWI to DTW without a single fixed slot. Its most common scheduled departure was 06:00, used on 250 of 365 flights. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

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 2601 runs 5 points better at 94.1%. 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 2601 quarter by quarter

Quarter by quarter DL 2601 held fairly steady: 92.4% in Jul–Sep 2025, 95.5% in Oct–Dec 2025, 92.0% in Jan–Mar 2026 and 96.6% in Apr–Jun 2026. A spread of 5 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202592 flights92.4%
Oct–Dec 202592 flights95.5%
Jan–Mar 202690 flights92.0%
Apr–Jun 202691 flights96.6%

Scale runs 85% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, DL 2601 did best on Wednesday at 100.0% on time and worst on Monday at 87.8%. Each day rests on about 52 flights, so a gap of 12 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 2601 runs late

One category carries most of the weight here. Carrier accounts for 62% of the 1,885 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
62%
Late-arriving aircraft
33%
National Airspace System
4%

The largest share of delay minutes, 62%, 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 1,178 of the 1,885 delay minutes reported here. The split is drawn from 1,885 delay minutes reported on DL 2601.

Cancellations sit at 2.47% 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 2.0% 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.

Every one of the 365 flights under DL 2601 in the data flew BWI to DTW. 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. 365 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 2601

For a booking, read DL 2601 as 94.1% on time with 2.47% cancelled over 365 flights. Those are rates from the past twelve months, not a forecast for any particular day.
