Historical statistics for July 2025 to June 2026, not live status. For today’s DL 2510, check with Delta Air Lines.

DL 2510 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 close to two hours. That rests on 321 flights, with a median arrival 12 minutes early.

Set against the rest of the country, DL 2510's record is 16 points better than the US average of 77.6%. That gap is worth roughly 163 fewer late arrivals for every thousand flights.

These figures cover 321 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 2510 flies

DL 2510 flies LGA to MSP without a single fixed slot. Its most common scheduled departure was 06:00, used on 150 of 321 flights, with 06:05 (141 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 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 2510 runs 5 points better at 93.9%. 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 2510 quarter by quarter

Quarter by quarter DL 2510 held fairly steady: 93.4% in Jul–Sep 2025, 92.1% in Oct–Dec 2025, 95.7% in Jan–Mar 2026 and 94.4% in Apr–Jun 2026. A spread of 4 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

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

By weekday, DL 2510 ranged from 89.8% on Sunday to 98.0% on Monday. With about 46 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 2510 runs late

One category carries most of the weight here. Carrier accounts for 58% of the 2,107 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
58%
Late-arriving aircraft
24%
National Airspace System
18%

The largest share of delay minutes, 58%, 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 1,232 of the 2,107 delay minutes reported here. The split is drawn from 2,107 delay minutes reported on DL 2510.

Cancellations run at 3.12%, against 1.81% nationally. That is about one flight in 30 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 3.9% 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 1,020 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 321 flights under DL 2510 in the data flew LGA to MSP. 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. 321 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 2510

For a booking, the cancellation rate is the figure to plan around on DL 2510: 3.12% of its 321 scheduled flights did not operate. A late arrival costs close to two hours, but a cancellation costs the day, so leave a later option open.
