This route carries a cancellation problem, not just a delay problem: 7.8% of scheduled flights never operate, against 1.9% nationally. Of the ones that do fly, about four flights in five arrive on time, worth a B− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 916 MYR to EWR flights, with a median arrival 10 minutes early.
Best time to fly MYR to EWR: a 5am–8am departure, ideally on a Wednesday. Flights in that window arrived on time 86.4% of the time and Wednesday flights 84.7%, against 80.4% for the route overall.
The US average over the same twelve months is 77.3%, so there is little to separate this route from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Book the early departure. Flights leaving between 5am–8am arrive on time 86.4% of the time, against 71.3% for the evening window. That is 15 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 11am–2pm window is the busiest, with 310 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 27 points from best month to worst, which is wide. An annual average tells you very little about the week you are actually flying, so read the strip rather than the headline if your dates are fixed.
April is the best month on the calendar at 93.5% on time. Shoulder season thins the schedule and takes the summer weather with it, and the operation gets its margin back. September was the busiest month here, with 113 flights.
Across the week, Wednesday is the strongest day at 84.7% on time and Friday the weakest at 76.7%, a spread of 8 points.
Delay causes
Why this route gets delayed
National Airspace System accounts for 45% of the 13,000 delay minutes carriers reported here, and the remaining four split what is left.
- 45%National Airspace System
- 38%Late-arriving aircraft
- 15%Carrier
- 2%Extreme weather
38% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 13,000 reported delay minutes here, that single category outweighs weather by 24 to one. The split is drawn from 13,455 reported delay minutes.
45% 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 6,096 minutes out of 13,000, against a national NAS share of 21%.
Cancellations run at 7.75%, against 1.89% 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 stage length
What a delay here actually costs
9.0% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
The 550 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.
The return leg runs 79.2% on time across 913 flights, within about a point of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
One caution: this is a thin sample. 916 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 this route
Put together: the delay figures matter less here than the 7.75% cancellation rate. A late arrival costs you a little over an hour; a cancelled flight costs you the day. Book the 5am–8am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 842 completed flights over 12 months sit behind that.
Common questions
MYR to EWR questions
How often is MYR to EWR delayed?
About one flight in five arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 19.6% of the 916 flights in this analysis, against 22.7% nationally. Delayed flights are late by a little over an hour on average.
How reliable is MYR to EWR compared with the rest of the country?
80.4% of flights arrive on time here against a national 77.3%, a difference of 3 points in its favour. That is worth a B− on this site's grading scale.
What time of day has the fewest delays on MYR to EWR?
The 5am–8am departure window is the strongest at 86.4% on time. The 5pm–8pm window is the weakest at 71.3%, 15 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.
How bad are November delays on MYR to EWR?
November is the weakest month at 66.7% on time, compared with 93.5% in April. Across the year that is 27 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
