Historical statistics for July 2025 to June 2026, not live status. For today’s AA 177, check with American Airlines.

AA 177 draws a D−. About one flight in three arrives at least 15 minutes late, and the typical late arrival is about an hour behind schedule. Build slack into anything you connect to. That rests on 362 flights, with a median arrival 1 minute late.

The national on-time rate over the same period is 77.6%, so AA 177 runs 14 points behind the country as a whole. Across a thousand flights that is about 137 extra late arrivals.

These figures cover 362 flights between July 2025 and June 2026. Beyond the headline rate, 11.5% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When AA 177 flies

AA 177 flies JFK to SFO without a single fixed slot. Its most common scheduled departure was 21:00, used on 62 of 362 flights, with 20:30 (46 flights) and 20:25 (44 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 21:00 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and AA 177 runs 7 points worse at 63.9%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Against the route

AA 177 next to JFK to SFO

Across the year

AA 177 quarter by quarter

AA 177 did not run the same all year. Its best quarter was Jan–Mar 2026 at 73.2% on time and its weakest Apr–Jun 2026 at 51.6%, a swing of 22 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.

Jan–Mar 202690 flights73.2%

Scale runs 45% to 80%. Rows with fewer than 30 flights show a dash.

By weekday, AA 177 did best on Tuesday at 78.0% on time and worst on Thursday at 54.2%. Each day rests on about 52 flights, so a gap of 24 points is worth noticing but could still narrow in another year.

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 7,739 reported delay minutes.

Late-arriving aircraft
41%
National Airspace System
33%
Carrier
21%
Extreme weather
4%

41% 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 7,739 reported delay minutes here, that single category outweighs weather by 9 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 7,739 delay minutes reported on AA 177.

Cancellations run at 3.04%, against 1.81% nationally. That is roughly one flight in 30 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

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 11.5% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum 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: 3.04% 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.
