Historical statistics for July 2025 to June 2026, not live status. For today’s YX 4621, 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 4621 draws a C−. 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 303 flights, with a median arrival 3 minutes early.
The national on-time rate over the same period is 77.6%, so YX 4621 runs 12 points behind the country as a whole. Across a thousand flights that is about 116 extra late arrivals.

These figures cover 303 flights between July 2025 and June 2026. Beyond the headline rate, 14.4% 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 4621 flies
YX 4621 flies ORF to LGA without a single fixed slot. Its most common scheduled departure was 12:50, used on 51 of 303 flights, with 13:49 (44 flights) and 13:42 (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 12:50 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and YX 4621 runs 13 points worse at 66.0%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
YX 4621 quarter by quarter
YX 4621 did not run the same all year. Its best quarter was Apr–Jun 2026 at 78.0% on time and its weakest Oct–Dec 2025 at 57.0%, a swing of 21 points on roughly 76 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 202587 flights57.0%
- Oct–Dec 202581 flights57.0%
- Jan–Mar 202685 flights77.6%
- Apr–Jun 202650 flights78.0%
Scale runs 50% to 85%. Rows with fewer than 30 flights show a dash.
By weekday, YX 4621 did best on Saturday at 77.8% on time and worst on Sunday at 57.5%. Each day rests on about 43 flights, so a gap of 20 points is worth noticing but could still narrow in another year.
Delay causes
Why YX 4621 runs late
One category carries most of the weight here. National Airspace System accounts for 53% of the 6,852 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.
- 53%National Airspace System
- 33%Late-arriving aircraft
- 8%Extreme weather
- 7%Carrier
53% 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 3,608 minutes out of 6,852, against a national NAS share of 21%. The split is drawn from 6,852 delay minutes reported on YX 4621.
Cancellations run at 3.63%, against 1.81% nationally. That is roughly 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
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 14.4% 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 one other city pair in the data, including JAN to DCA (6), but none flew often enough under YX 4621 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ORF to LGA only.
One caution: this is a thin sample. 303 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 4621
For a booking, the cancellation rate is the figure to plan around on YX 4621: 3.63% of its 303 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.
