Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with United Airlines.

United on EWR to MYR earns an A. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 10 points better than the national rate of 77.6%. When something does go wrong the average delay runs about an hour. That rests on 133 flights. The strongest carrier on the route with a full sample, Republic Airways, flew 487 at 82.1% on time.

Set against the rest of the country, United's EWR to MYR record is 10 points better than the US average of 77.6%. That gap is worth roughly 102 fewer late arrivals for every thousand flights.

Every carrier on EWR to MYR, 1,002 flights

These figures cover 133 flights between July 2025 and June 2026. The median arrival is 15 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.

Carrier by carrier

United against every carrier on EWR to MYR

United flew 133 of the 1,002 flights on EWR to MYR, about 13% of it. Its 87.8% on time is 9 points better than the route as a whole, which runs 78.5%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from United at 87.8% to Spirit at 70.5%.

The choice of carrier is not cosmetic here. Republic Airways arrives on time 82.1% of the time; Spirit Airlines manages 70.5%. Sample sizes sit next to every figure, because a two-point gap across 382 flights means less than a ten-point one.

Spirit Airlines cancels 6.8% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.

Departure window

When United runs best on this route

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 29 points, against 12 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

5am–8am42 flights95.2%
8am–11am60 flights93.2%
11am–2pm31 flights66.7%

Scale runs 60% to 100%. Rows with fewer than 30 flights show a dash.

The weak window here is the middle of the day, not the evening: 11am–2pm runs 66.7% on time against 95.2% for 5am–8am. That shape usually means a departure bank rather than an accumulating delay, so the recovery later in the afternoon is real rather than noise. The 8am–11am window is the busiest, with 60 flights scheduled in it.

Across the year

Jul–Sep 202566 flights92.3%

Scale runs 60% to 100%. Rows with fewer than 30 flights show a dash.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 87.8% on time across 133 flights.

United on EWR to MYR did not run the same all year. Its best quarter was Apr–Jun 2026 at 97.1% on time and its weakest Oct–Dec 2025 at 67.7%, a swing of 29 points on roughly 44 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.

Delay causes

Why United runs late on this route

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 1,032 reported delay minutes.

Carrier
41%
National Airspace System
30%
Late-arriving aircraft
29%

The largest share of delay minutes, 41%, 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 421 of the 1,032 delay minutes reported here. The split is drawn from 1,032 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 95.2% on time here.

Cancellations sit at 1.50% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and stage length

What a delay here costs

Badly late arrivals are rare here: only 3.1% 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 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. 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 return leg is a different operation and performs like one: it runs 82.8% on time across 133 flights, 5 points below this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 5 points of difference.

One caution: this is a thin sample. 133 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 United on EWR to MYR

Put together: treat all of this as provisional. 133 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 87.8% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 131 completed flights over 12 months sit behind that.
