Historical statistics for July 2025 to June 2026, not live status. For today’s YX 5730, check with Republic Airways. Republic Airways flies under contract for larger airlines, so a ticket for this flight may show a different airline code and number.

YX 5730 lands a B−, level with the national rate of 77.6%. Roughly one flight in five 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 297 flights, with a median arrival 7 minutes early.

These figures cover 297 flights between July 2025 and June 2026. Beyond the headline rate, 10.0% 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 5730 flies

YX 5730 is scheduled to leave Boston (BOS) at 14:00 local time and reach New York (LGA) at 15:25. That slot held for 297 of the 297 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

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

A 14:00 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and YX 5730 runs 6 points better at 77.9%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Against the route

YX 5730 next to BOS to LGA

Every carrier on BOS to LGA combined arrived on time 77.7% of the time across 7,251 flights, so YX 5730 is about level with it. Republic flew 6,708 flights on the same city pair under all its flight numbers, including this one, and those ran 76.6% on time. Across its whole network Republic Airways managed 78.5%, close to this flight's figure.

Across the year

YX 5730 quarter by quarter

YX 5730 did not run the same all year. Its best quarter was Apr–Jun 2026 at 84.2% on time and its weakest Jan–Mar 2026 at 71.6%, a swing of 13 points on roughly 74 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 5730 ranged from 72.3% on Thursday to 83.3% on Tuesday. With about 42 flights behind each day, a spread of 11 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why YX 5730 runs late

One category carries most of the weight here. National Airspace System accounts for 59% of the 4,382 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.

Carrier
20%
Late-arriving aircraft
16%
Extreme weather
6%

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 2,578 minutes out of 4,382, against a national NAS share of 21%. The split is drawn from 4,382 delay minutes reported on YX 5730.

Cancellations run at 5.39%, against 1.81% nationally. That is about 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

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 10.0% 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.

The same number turns up on two other city pairs in the data, including LGA to ORF (10) and DTW to LEX (2), but none flew often enough under YX 5730 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to BOS to LGA only.

One caution: this is a thin sample. 297 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 5730

For a booking, the cancellation rate is the figure to plan around on YX 5730: 5.39% of its 297 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.
