These figures cover 348 flights between July 2025 and June 2026. Beyond the headline rate, 8.4% 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 YX 5808 flies

YX 5808 flies BOS to JFK without a single fixed slot. Its most common scheduled departure was 13:10, used on 70 of 348 flights, with 13:25 (48 flights) and 13:00 (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 13:10 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and YX 5808 runs 4 points worse at 75.0%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

YX 5808 quarter by quarter

By weekday, YX 5808 ranged from 69.4% on Saturday to 81.2% on Tuesday. With about 50 flights behind each day, a spread of 12 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why YX 5808 runs late

One category carries most of the weight here. National Airspace System accounts for 57% 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.

57% 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 2,607 minutes out of 4,553, against a national NAS share of 21%. The split is drawn from 4,553 delay minutes reported on YX 5808.

Cancellations run at 4.60%, against 1.81% nationally. That is roughly one flight in twenty 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

8.4% 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 55 minutes, which a normal layover absorbs.

The same number turns up on one other city pair in the data, including CHS to BOS (16), but none flew often enough under YX 5808 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to BOS to JFK only.

One caution: this is a thin sample. 348 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 YX 5808

For a booking, the cancellation rate is the figure to plan around on YX 5808: 4.60% of its 348 scheduled flights did not operate. A late arrival costs about 55 minutes, but a cancellation costs the day, so leave a later option open.
