Historical statistics for July 2025 to June 2026, not live status. For today’s YX 4696, 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 4696 draws a D−. About one flight in three arrives at least 15 minutes late, and the typical late arrival is a little over an hour behind schedule. Build slack into anything you connect to. That rests on 291 flights, with a median arrival 7 minutes early.
The national on-time rate over the same period is 77.6%, so YX 4696 runs 13 points behind the country as a whole. Across a thousand flights that is about 127 extra late arrivals.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 19:55 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and YX 4696 runs 3 points worse at 64.9%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year
YX 4696 quarter by quarter
YX 4696 did not run the same all year. Its best quarter was Apr–Jun 2026 at 72.9% on time and its weakest Oct–Dec 2025 at 53.4%, a swing of 20 points on roughly 73 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.

- Oct–Dec 202577 flights53.4%
- Jan–Mar 202666 flights61.7%

By weekday, YX 4696 ranged from 58.7% on Thursday to 67.4% on Monday. With about 42 flights behind each day, a spread of 9 points is inside normal variation, so the day you fly is not worth changing for this flight.
Delay causes
Why YX 4696 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 64% of the 6,694 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.
- 64%Late-arriving aircraft
- 20%National Airspace System
- 16%Carrier
- 0%Extreme weather
- 0%Security
64% 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 6,694 reported delay minutes here, that single category outweighs weather by 64 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 6,694 delay minutes reported on YX 4696.
Cancellations run at 8.25%, against 1.81% nationally. That is about one flight in twelve 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. 16.2% 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.
Every one of the 291 flights under YX 4696 in the data flew LGA to MEM. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 291 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 4696
For a booking, the cancellation rate is the figure to plan around on YX 4696: 8.25% of its 291 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.
