Historical statistics for July 2025 to June 2026, not live status. For today’s DL 787, check with Delta Air Lines.

DL 787 earns an A. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 9 points better than the national rate of 77.6%. When something does go wrong the average delay runs about 50 minutes. That rests on 365 flights, with a median arrival 15 minutes early.

Set against the rest of the country, DL 787's record is 9 points better than the US average of 77.6%. That gap is worth roughly 93 fewer late arrivals for every thousand flights.

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 787 flies

DL 787 flies GEG to ATL without a single fixed slot. Its most common scheduled departure was 12:55, used on 38 of 365 flights. 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 12:55 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and DL 787 runs 8 points better at 86.9%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

DL 787 quarter by quarter

DL 787 did not run the same all year. Its best quarter was Jan–Mar 2026 at 93.0% on time and its weakest Oct–Dec 2025 at 81.3%, a swing of 12 points on roughly 91 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 787 did best on Friday at 94.0% on time and worst on Thursday at 80.8%. Each day rests on about 52 flights, so a gap of 13 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 787 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 43% of the 2,310 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.

  • Late-arriving aircraft
    43%
  • National Airspace System
    37%
  • Carrier
    18%
  • Extreme weather
    2%

43% 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 2,310 reported delay minutes here, that single category outweighs weather by 19 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 2,310 delay minutes reported on DL 787.

Cancellations sit at 1.37% against a national 1.81%, which is ordinary. Diversions add another 0.27%.

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 8.1% 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.

At 1,969 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.

DL 787 is not only a GEG to ATL flight. It also flew ATL to GEG (365 flights, 85.0% 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. 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.
