Historical statistics for July 2025 to June 2026, not live status. For today’s AA 179, check with American Airlines.

AA 179 lands a B, 5 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 365 flights, with a median arrival 13 minutes early.

Set against the rest of the country, AA 179's record is 5 points better than the US average of 77.6%. That gap is worth roughly 50 fewer late arrivals for every thousand flights.

These figures cover 365 flights between July 2025 and June 2026. The median arrival is 13 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 179 flies

AA 179 flies JFK to SFO without a single fixed slot. Its most common scheduled departure was 08:00, used on 66 of 365 flights, with 07:30 (41 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 08:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and AA 179 runs level with that at 82.6%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

AA 179 quarter by quarter

AA 179 did not run the same all year. Its best quarter was Jul–Sep 2025 at 94.6% on time and its weakest Jan–Mar 2026 at 71.4%, a swing of 23 points on roughly 91 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

Jul–Sep 202592 flights94.6%
Oct–Dec 202592 flights90.0%
Jan–Mar 202690 flights71.4%

Scale runs 65% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, AA 179 did best on Wednesday at 90.2% on time and worst on Saturday at 74.5%. Each day rests on about 52 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Delay causes

Why AA 179 runs late

One category carries most of the weight here. Carrier accounts for 47% of the 3,514 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.

47%
National Airspace System
45%
Late-arriving aircraft
6%
Extreme weather
2%

The largest share of delay minutes, 47%, 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 1,659 of the 3,514 delay minutes reported here. The split is drawn from 3,514 delay minutes reported on AA 179.

Cancellations sit at 2.19% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 4.5% 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 2,586 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 365 flights under AA 179 in the data flew JFK to SFO. 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. 365 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.
