Historical statistics for July 2025 to June 2026, not live status. For today’s AS 114, check with Alaska Airlines.

AS 114 lands a B, about a point worse than the national rate of 77.6%. About one flight in four arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 251 flights, with a median arrival 6 minutes early.

These figures cover 251 flights between July 2025 and June 2026. Beyond the headline rate, 10.3% 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 AS 114 flies

AS 114 flies JFK to SFO without a single fixed slot. Its most common scheduled departure was 16:39, used on 50 of 251 flights, with 13:00 (44 flights) and 18:57 (36 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 16:39 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and AS 114 runs 4 points better at 76.5%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Against the route

AS 114 next to JFK to SFO

Across the year

AS 114 quarter by quarter

AS 114 did not run the same all year. Its best quarter was Jan–Mar 2026 at 84.9% on time and its weakest Oct–Dec 2025 at 69.8%, a swing of 15 points on roughly 84 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 202677 flights84.9%

By weekday, AS 114 did best on Wednesday at 85.3% on time and worst on Sunday at 70.6%. Each day rests on about 36 flights, so a gap of 15 points is worth noticing but could still narrow in another year.

Delay causes

Why AS 114 runs late

One category carries most of the weight here. National Airspace System accounts for 53% of the 4,553 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.

  • National Airspace System

  • Late-arriving aircraft
    31%
  • Carrier
    15%
  • Extreme weather
    1%
  • Security
    0%

53% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 2,423 minutes out of 4,553, against a national NAS share of 21%. The split is drawn from 4,553 delay minutes reported on AS 114.

Cancellations run at 2.79%, against 1.81% nationally. That is roughly one flight in 40 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. 10.3% 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 251 flights under AS 114 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. 251 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 AS 114

For a booking, the cancellation rate is the figure to plan around on AS 114: 2.79% of its 251 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
