Historical statistics for July 2025 to June 2026, not live status. For today’s DL 1714, check with Delta Air Lines.

DL 1714 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 15 points better than the national rate of 77.6%. When something does go wrong the average delay runs about an hour. That rests on 349 flights, with a median arrival 20 minutes early.

Set against the rest of the country, DL 1714's record is 15 points better than the US average of 77.6%. That gap is worth roughly 149 fewer late arrivals for every thousand flights.

These figures cover 349 flights between July 2025 and June 2026. The median arrival is 20 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 1714 flies

DL 1714 flies LAX to SEA without a single fixed slot. Its most common scheduled departure was 09:45, used on 62 of 349 flights, with 09:56 (60 flights) and 09:50 (55 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 09:45 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and DL 1714 runs 8 points better at 92.5%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Against the route

DL 1714 next to LAX to SEA

Across the year

DL 1714 quarter by quarter

Quarter by quarter DL 1714 held fairly steady: 96.7% in Jul–Sep 2025, 92.5% in Oct–Dec 2025, 89.4% in Jan–Mar 2026 and 91.1% in Apr–Jun 2026. A spread of 7 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

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

By weekday, DL 1714 ranged from 87.8% on Friday to 98.0% on Saturday. With about 50 flights behind each day, a spread of 10 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 1714 runs late

One category carries most of the weight here. Carrier accounts for 73% of the 1,684 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
73%
Late-arriving aircraft
20%
National Airspace System
4%
Security
3%

The largest share of delay minutes, 73%, 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 1,223 of the 1,684 delay minutes reported here. The split is drawn from 1,684 delay minutes reported on DL 1714.

Cancellations are rare at 0.57%, 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 2.6% 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.

The 954 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.

The same number turns up on one other city pair in the data, including ATL to GSO (16), but none flew often enough under DL 1714 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LAX to SEA only.

One caution: this is a thin sample. 349 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 1714

For a booking, DL 1714 has one of the better records a US domestic flight can show: 92.5% on time and 0.57% cancelled. That is a base rate, not a promise about any single day.
