Historical statistics for July 2025 to June 2026, not live status. For today’s YX 3642, 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.

These figures cover 250 flights between July 2025 and June 2026. The median arrival is 21 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 3642 flies
YX 3642 flies MEM to EWR without a single fixed slot. Its most common scheduled departure was 06:00, used on 197 of 250 flights. 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 06:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and YX 3642 runs 5 points better at 94.3%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

By weekday, YX 3642 ranged from 89.2% on Wednesday to 97.2% on Monday. With about 36 flights behind each day, a spread of 8 points is inside normal variation, so the day you fly is not worth changing for this flight.
Delay causes
Why YX 3642 runs late
One category carries most of the weight here. Carrier accounts for 57% of the 1,786 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.
- 57%Carrier
- 27%National Airspace System
- 16%Late-arriving aircraft
The largest share of delay minutes, 57%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 1,019 of the 1,786 delay minutes reported here. The split is drawn from 1,786 delay minutes reported on YX 3642.
Cancellations sit at 1.60% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 4.1% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
The 946 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 nine other city pairs in the data, including ORD to CMH (56), EWR to ILM (16) and IND to EWR (16), but none flew often enough under YX 3642 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to MEM to EWR only.
One caution: this is a thin sample. 250 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
