DL 2270 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 11 points better than the national rate of 77.6%. When something does go wrong the average delay runs roughly 55 minutes. That rests on 360 flights, with a median arrival 11 minutes early.

Set against the rest of the country, DL 2270's record is 11 points better than the US average of 77.6%. That gap is worth roughly 106 fewer late arrivals for every thousand flights.

These figures cover 360 flights between July 2025 and June 2026. The median arrival is 11 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 2270 flies

DL 2270 flies PHL to ATL without a single fixed slot. Its most common scheduled departure was 12:16, used on 46 of 360 flights, with 12:07 (43 flights) and 12:37 (41 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 12:16 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and DL 2270 runs 9 points better at 88.2%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

DL 2270 quarter by quarter

Quarter by quarter DL 2270 held fairly steady: 90.1% in Jul–Sep 2025, 82.4% in Oct–Dec 2025, 91.6% in Jan–Mar 2026 and 89.2% in Apr–Jun 2026. A spread of 9 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, DL 2270 ranged from 82.7% on Thursday to 94.2% on Wednesday. With about 51 flights behind each day, a spread of 12 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 2270 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 67% of the 2,200 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.

Extreme weather

67% 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 2,200 reported delay minutes here, that single category outweighs weather by 40 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 2,200 delay minutes reported on DL 2270.

Cancellations run at 3.06%, against 1.81% nationally. That is roughly 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 3.2% 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 666 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.

DL 2270 is not only a PHL to ATL flight. It also flew ATL to PHL (351 flights, 86.2% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.

One caution: this is a thin sample. 360 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 2270

For a booking, the cancellation rate is the figure to plan around on DL 2270: 3.06% of its 360 scheduled flights did not operate. A late arrival costs roughly 55 minutes, but a cancellation costs the day, so leave a later option open.
