These figures cover 339 flights between July 2025 and June 2026. The median arrival is 16 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 AA 1667 flies
AA 1667 flies SEA to DFW without a single fixed slot. Its most common scheduled departure was 07:44, used on 54 of 339 flights, with 07:31 (41 flights) and 07:35 (37 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 07:44 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and AA 1667 runs level with that at 89.7%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Delay causes
Why AA 1667 runs late
One category carries most of the weight here. Carrier accounts for 61% of the 4,351 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.
- 61%Carrier
- 24%Late-arriving aircraft
- 14%National Airspace System
- 1%Extreme weather
The largest share of delay minutes, 61%, 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 2,645 of the 4,351 delay minutes reported here. The split is drawn from 4,351 delay minutes reported on AA 1667.
Cancellations sit at 1.77% against a national 1.81%, which is ordinary. Diversions add another 1.18%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 4.3% 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 1,660 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.
Every one of the 339 flights under AA 1667 in the data flew SEA to DFW. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 339 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.
