Historical statistics for July 2025 to June 2026, not live status. For today’s YX 4535, 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 4535 earns an A−. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 9 points better than the national rate of 77.6%. When something does go wrong the average delay runs an hour and a half. That rests on 295 flights, with a median arrival 15 minutes early.

Set against the rest of the country, YX 4535's record is 9 points better than the US average of 77.6%. That gap is worth roughly 85 fewer late arrivals for every thousand flights.

These figures cover 295 flights between July 2025 and June 2026. The median arrival is 15 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Schedule

When YX 4535 flies

YX 4535 flies OKC to LGA without a single fixed slot. Its most common scheduled departure was 06:05, used on 74 of 295 flights, with 06:34 (38 flights) and 06:00 (32 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 06:05 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and YX 4535 runs 3 points worse at 86.1%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Against the route

YX 4535 next to OKC to LGA

Across the year

YX 4535 quarter by quarter

YX 4535 did not run the same all year. Its best quarter was Jul–Sep 2025 at 92.6% on time and its weakest Jan–Mar 2026 at 78.6%, a swing of 14 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.

Jul–Sep 202588 flights92.6%
Oct–Dec 202581 flights83.1%
Jan–Mar 202664 flights78.6%
Apr–Jun 202662 flights88.1%

Scale runs 70% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, YX 4535 ranged from 77.8% on Thursday to 89.6% on Wednesday. With about 42 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 4535 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 3,491 reported delay minutes.

Carrier
40%
Late-arriving aircraft
29%
National Airspace System
18%
Extreme weather
14%

Extreme weather accounts for 14% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.2 times the usual weather exposure. The split is drawn from 3,491 delay minutes reported on YX 4535.

Cancellations run at 7.12%, against 1.81% nationally. That is about one flight in fifteen 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

6.2% 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 an hour and a half, which a normal layover absorbs.

The 1,341 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

The same number turns up on one other city pair in the data, including MSP to ORD (7), but none flew often enough under YX 4535 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to OKC to LGA only.

One caution: this is a thin sample. 295 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 4535

For a booking, the cancellation rate is the figure to plan around on YX 4535: 7.12% of its 295 scheduled flights did not operate. A late arrival costs an hour and a half, but a cancellation costs the day, so leave a later option open.
