Across the year

AA 177 quarter by quarter

AA 177 did not run the same all year. Its best quarter was Jul–Sep 2025 at 80.0% on time and its weakest Jul–Sep 2026 at 45.6%, a swing of 34 points on roughly 72 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.

By weekday, AA 177 did best on Tuesday at 71.4% on time and worst on Thursday at 47.9%. Each day rests on about 52 flights, so a gap of 24 points is worth noticing but could still narrow in another year.

Arrival by arrival

How late AA 177 runs when it is late

AA 177 often beats the schedule: 107 of 346 completed flights, 31%, arrived 15 minutes or more early. The 137 late arrivals split 50 under half an hour, 44 between 30 and 60 minutes, and 43 an hour or more.

Share of 346 completed flights by arrival against schedule.

20 of 113 late departures made up the time and arrived on time, 18% of them. In the other direction, 44 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at SFO.

The worst days

Worst days for AA 177

The latest arrival of the period was on 12 June 2026, 14 hours behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.

Delay causes

Why AA 177 runs late

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 8,894 reported delay minutes.

Late-arriving aircraft
36%
National Airspace System
30%
Carrier
28%
Extreme weather
6%

36% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 8,894 reported delay minutes here, that single category outweighs weather by 7 to one. The split is drawn from 8,894 delay minutes reported on AA 177.

Cancellations run at 3.87%, against 1.89% nationally. That is about one flight in 25 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.

Connections and routes

What a delay on this flight costs

12.4% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.

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 362 flights under AA 177 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. 362 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 AA 177

For a booking, the cancellation rate is the figure to plan around on AA 177: 3.87% of its 362 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
