Historical statistics for July 2025 to June 2026, not live status. For today’s AA 1677, check with American Airlines.
AA 1677 earns a B+. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 6 points better than the national rate of 77.6%. When something does go wrong the average delay runs about 2.3 hours. That rests on 269 flights, with a median arrival 6 minutes early.
Set against the rest of the country, AA 1677's record is 6 points better than the US average of 77.6%. That gap is worth roughly 64 fewer late arrivals for every thousand flights.

These figures cover 269 flights between July 2025 and June 2026. The median arrival is 6 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 1677 flies
AA 1677 flies SMF to PHX without a single fixed slot. Its most common scheduled departure was 12:59, used on 68 of 269 flights, with 13:02 (49 flights) and 12:57 (45 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 12:59 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and AA 1677 runs 5 points better at 84.0%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
AA 1677 quarter by quarter
Quarter by quarter AA 1677 held fairly steady: 87.9% in Jul–Sep 2025, 83.5% in Oct–Dec 2025 and 80.2% in Jan–Mar 2026. A spread of 8 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, AA 1677 did best on Wednesday at 89.7% on time and worst on Monday at 73.7%. Each day rests on about 38 flights, so a gap of 16 points is worth noticing but could still narrow in another year.
Delay causes
Why AA 1677 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 59% of the 5,858 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.
- 59%Late-arriving aircraft
- 36%Carrier
- 4%National Airspace System
- 0%Extreme weather
59% 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 5,858 reported delay minutes here, that single category outweighs weather by 59 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 5,858 delay minutes reported on AA 1677.
Cancellations are rare at 0.37%, 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
6.3% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about 2.3 hours, which a normal layover absorbs.
The 647 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.
AA 1677 is not only a SMF to PHX flight. It also flew PHX to SMF (268 flights, 87.3% 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. 269 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.
