These figures cover 300 flights between September 2025 and August 2026. The median arrival is 13 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.

Across the year

DL 2688 quarter by quarter

DL 2688 did not run the same all year. Its best quarter was Jul–Sep 2026 at 97.9% on time and its weakest Oct–Dec 2025 at 83.6%, a swing of 14 points on roughly 75 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 2688 did best on Wednesday at 97.6% on time and worst on Monday at 84.1%. Each day rests on about 43 flights, so a gap of 14 points is worth noticing but could still narrow in another year.

Why DL 2688 runs late

Carrier accounts for 66% of the 1,372 delay minutes carriers reported here, and the remaining four split what is left.

Carrier
66%
National Airspace System
23%
Late-arriving aircraft
10%

The largest share of delay minutes, 66%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 910 of the 1,372 delay minutes reported here. The split is drawn from 1,372 delay minutes reported on DL 2688.

Cancellations run at 4.00%, 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 2.8% 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 981 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.

DL 2688 is not only a MSP to PHL flight. It also flew PHL to MSP (300 flights, 85.6% 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. 300 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 2688
