Historical statistics for July 2025 to June 2026, not live status. For today’s DL 2526, check with Delta Air Lines.

DL 2526 earns an A. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 10 points better than the national rate of 77.6%. When something does go wrong the average delay runs about an hour. That rests on 262 flights, with a median arrival 12 minutes early.

Set against the rest of the country, DL 2526's record is 10 points better than the US average of 77.6%. That gap is worth roughly 96 fewer late arrivals for every thousand flights.

These figures cover 262 flights between July 2025 and June 2026. The median arrival is 12 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 2526 flies

DL 2526 flies BWI to MSP without a single fixed slot. Its most common scheduled departure was 11:38, used on 39 of 262 flights, with 15:00 (31 flights) and 11:45 (30 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 11:38 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and DL 2526 runs 8 points better at 87.2%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

DL 2526 quarter by quarter

Quarter by quarter DL 2526 held fairly steady: 87.0% in Jul–Sep 2025, 84.8% in Oct–Dec 2025, 90.0% in Jan–Mar 2026 and 87.5% 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.

By weekday, DL 2526 did best on Wednesday at 97.5% on time and worst on Sunday at 73.5%. Each day rests on about 37 flights, so a gap of 24 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 2526 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 50% of the 1,949 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.

50% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 1,949 reported delay minutes here, that single category outweighs weather by 50 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 1,949 delay minutes reported on DL 2526.

Cancellations sit at 1.15% against a national 1.81%, which is ordinary. Diversions add another 0.38%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 3.5% 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 936 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 MSP to BWI (212), PBI to LGA (55) and ATL to CAE (1), but none flew often enough under DL 2526 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to BWI to MSP only.

One caution: this is a thin sample. 262 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 2526

For a booking, DL 2526 has one of the better records a US domestic flight can show: 87.2% on time and 1.15% cancelled. That is a base rate, not a promise about any single day.
