Historical statistics for July 2025 to June 2026, not live status. For today’s DL 888, check with Delta Air Lines.

DL 888 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 roughly 50 minutes. That rests on 314 flights, with a median arrival 12 minutes early.

Set against the rest of the country, DL 888's record is 16 points better than the US average of 77.6%. That gap is worth roughly 156 fewer late arrivals for every thousand flights.

These figures cover 314 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 888 flies

DL 888 flies PDX to ATL without a single fixed slot. Its most common scheduled departure was 22:10, used on 71 of 314 flights, with 22:05 (68 flights) and 21:45 (51 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 22:10 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and DL 888 runs 23 points better at 93.2%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Against the route

DL 888 next to PDX to ATL

Across the year

DL 888 quarter by quarter

Quarter by quarter DL 888 held fairly steady: 90.2% in Jul–Sep 2025, 89.7% in Oct–Dec 2025, 98.6% in Jan–Mar 2026 and 95.5% 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.

Jul–Sep 202582 flights90.2%
Oct–Dec 202587 flights89.7%
Jan–Mar 202678 flights98.6%

Scale runs 80% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, DL 888 ranged from 89.2% on Saturday to 97.8% on Tuesday. With about 45 flights behind each day, a spread of 9 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 888 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 54% of the 1,081 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.

54%

34%

54% 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 1,081 reported delay minutes here, that single category outweighs weather by 54 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 1,081 delay minutes reported on DL 888.

Cancellations are rare at 0.64%, below the national 1.81% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 1.6% 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 2,172 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.

The same number turns up on one other city pair in the data, including MCO to BOS (24), but none flew often enough under DL 888 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to PDX to ATL only.

One caution: this is a thin sample. 314 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 888

For a booking, DL 888 has one of the better records a US domestic flight can show: 93.2% on time and 0.64% cancelled. That is a base rate, not a promise about any single day.
