Historical statistics for July 2025 to June 2026, not live status. For today’s YX 4506, 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 4506 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 about an hour on average. That is a workable record, not a spotless one. That rests on 269 flights, with a median arrival 8 minutes early.

These figures cover 269 flights between July 2025 and June 2026. Beyond the headline rate, 8.9% 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 4506 flies
YX 4506 flies LGA to CAE without a single fixed slot. Its most common scheduled departure was 14:40, used on 82 of 269 flights, with 13:29 (46 flights) and 13:26 (35 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 14:40 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and YX 4506 runs 4 points better at 76.4%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
YX 4506 quarter by quarter
YX 4506 did not run the same all year. Its best quarter was Jul–Sep 2025 at 84.6% on time and its weakest Oct–Dec 2025 at 67.5%, a swing of 17 points on roughly 90 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 4506 did best on Saturday at 84.4% on time and worst on Sunday at 65.8%. Each day rests on about 38 flights, so a gap of 19 points is worth noticing but could still narrow in another year.
Delay causes
Why YX 4506 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 44% of the 3,859 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.
- 44%Late-arriving aircraft
- 31%National Airspace System
- 24%Carrier
- 1%Extreme weather
44% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 3,859 reported delay minutes here, that single category outweighs weather by 40 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 3,859 delay minutes reported on YX 4506.
Cancellations run at 3.35%, against 1.81% nationally. That is about one flight in 30 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
8.9% 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 an hour, which a normal layover absorbs.
The 617 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.
YX 4506 is not only a LGA to CAE flight. It also flew CAE to LGA (255 flights, 67.4% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.
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.

Booking YX 4506
