Across the year

YX 4601 quarter by quarter

YX 4601 did not run the same all year. Its best quarter was Apr–Jun 2026 at 80.4% on time and its weakest Oct–Dec 2025 at 62.7%, a swing of 18 points on roughly 67 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, YX 4601 did best on Friday at 80.5% on time and worst on Thursday at 57.9%. Each day rests on about 38 flights, so a gap of 23 points is worth noticing but could still narrow in another year.

Arrival by arrival

How late YX 4601 runs when it is late

YX 4601 often beats the schedule: 67 of 256 completed flights, 26%, arrived 15 minutes or more early. The 78 late arrivals split 19 under half an hour, 23 between 30 and 60 minutes, and 36 an hour or more.

Share of 256 completed flights by arrival against schedule.

Time lost at the gate mostly stays lost. Of 68 departures that left 15 minutes late or more, only 7 made it up before arrival. In the other direction, 17 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 LGA.

Delay causes

Why YX 4601 runs late

National Airspace System accounts for 59% of the 5,533 delay minutes carriers reported here, and the remaining four split what is left.

59% 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 3,278 minutes out of 5,533, against a national NAS share of 21%. The split is drawn from 5,533 delay minutes reported on YX 4601.

Cancellations run at 4.09%, 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

14.1% 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.

The 660 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.

The same number turns up on two other city pairs in the data, including LGA to IND (235) and LGA to PWM (44), but none flew often enough under YX 4601 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to IND to LGA only.

One caution: this is a thin sample. 269 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 4601

For a booking, the cancellation rate is the figure to plan around on YX 4601: 4.09% of its 269 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.
