This route carries a cancellation problem, not just a delay problem: 5.0% 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 913 EWR to MYR flights, with a median arrival 10 minutes early.
Best time to fly EWR to MYR: a 5am–8am departure, ideally on a Wednesday. Flights in that window arrived on time 89.4% of the time and Wednesday flights 84.7%, against 79.2% 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.

Departure window
The best time of day to leave
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 31 points, against half a point between the best and worst carrier.

Scale runs 50% to 95%.
The 8pm–5am window is where this operation falls apart: 58.6% on time, against 89.4% for the 5am–8am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 2pm–5pm window is the busiest, with 247 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 28 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.
December is the weak month at 67.7% on time, against 95.2% in May. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. September was the busiest month here, with 113 flights.
Across the week, Wednesday is the strongest day at 84.7% on time and Sunday the weakest at 72.0%, a spread of 13 points.
Delay causes
Why this route gets delayed
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 13,000 reported delay minutes.
- 41%National Airspace System
- 30%Late-arriving aircraft
- 23%Carrier
- 5%Extreme weather
- 0%Security
41% 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 5,273 minutes out of 13,000, against a national NAS share of 21%. The split is drawn from 12,810 reported delay minutes.
The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 89.4% on time here.
Cancellations run at 5.04%, against 1.89% nationally. That is about one flight in twenty 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
8.4% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.
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 80.4% on time across 916 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. 913 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 5.04% 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. 866 completed flights over 12 months sit behind that.
Common questions
EWR to MYR questions
How often is EWR to MYR 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 20.8% of the 913 flights in this analysis, against 22.7% nationally. Delayed flights are late by a little over an hour on average.
How reliable is EWR to MYR compared with the rest of the country?
79.2% of flights arrive on time here against a national 77.3%, a difference of 2 points in its favour. That is worth a B− on this site's grading scale.
What time of day has the fewest delays on EWR to MYR?
The 5am–8am departure window is the strongest at 89.4% on time. The 8pm–5am window is the weakest at 58.6%, 31 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 December delays on EWR to MYR?
December is the weakest month at 67.7% on time, compared with 95.2% in May. Across the year that is 28 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
