These figures cover 329 flights between September 2025 and August 2026. The median arrival is 19 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.

The latest arrival of the period was on 5 August 2026, 4 hours 56 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on five of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 5 August 2026 | 4 hours 56 minutes | Carrier |
| 25 June 2026 | 3 hours 23 minutes | Carrier |
| 7 November 2025 | 3 hours 4 minutes | Carrier |

Delay causes
Why DL 1714 runs late
Carrier accounts for 74% of the 1,971 delay minutes carriers reported here, and the remaining four split what is left.
- 74%Carrier
- 18%Late-arriving aircraft
- 5%National Airspace System
- 2%Security
The largest share of delay minutes, 74%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,461 of the 1,971 delay minutes reported here. The split is drawn from 1,971 delay minutes reported on DL 1714.
Cancellations are rare at 0.61%, below the national 1.89% 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 3.1% 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 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.
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. 329 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: 91.7% on time and 0.61% cancelled. That is a base rate, not a promise about any single day.
