Historical statistics for July 2025 to June 2026, not live status. For today’s YX 4807, 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 4807 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 a little over an hour on average. That is a workable record, not a spotless one. That rests on 270 flights, with a median arrival 11 minutes early.

These figures cover 270 flights between July 2025 and June 2026. Beyond the headline rate, 11.5% 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 4807 flies
YX 4807 flies LGA to MEM without a single fixed slot. Its most common scheduled departure was 13:16, used on 45 of 270 flights, with 13:25 (33 flights) and 14:40 (30 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 13:16 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and YX 4807 runs 3 points worse at 76.2%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
YX 4807 quarter by quarter
YX 4807 did not run the same all year. Its best quarter was Jan–Mar 2026 at 83.8% on time and its weakest Oct–Dec 2025 at 66.7%, 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 4807 did best on Tuesday at 83.8% on time and worst on Monday at 69.4%. Each day rests on about 39 flights, so a gap of 14 points is worth noticing but could still narrow in another year.
Delay causes
Why YX 4807 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 46% of the 4,654 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.
- 46%Late-arriving aircraft
- 32%National Airspace System
- 16%Carrier
- 5%Extreme weather
46% 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 4,654 reported delay minutes here, that single category outweighs weather by 9 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 4,654 delay minutes reported on YX 4807.
Cancellations run at 6.67%, 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
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 11.5% 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 963 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 4807 is not only a LGA to MEM flight. It also flew MEM to LGA (250 flights, 64.9% 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. 270 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.
