Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with United Airlines.
United on MYR to EWR lands a B−, 5 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That is a workable record, not a spotless one. That rests on 133 flights. The strongest carrier on the route with a full sample, Spirit Airlines, flew 386 at 80.7% on time.
Set against the rest of the country, United's MYR to EWR record is 5 points better than the US average of 77.6%. That gap is worth roughly 52 fewer late arrivals for every thousand flights.

These figures cover 133 flights between July 2025 and June 2026. Beyond the headline rate, 8.6% 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.
Carrier by carrier
United against every carrier on MYR to EWR
United flew 133 of the 1,006 flights on MYR to EWR, about 13% of it. Its 82.8% on time is 4 points better than the route as a whole, which runs 79.0%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from United at 82.8% to Republic at 76.7%.
The two carriers here are closely matched: 4 points separate the best from the worst. At that spread, schedule and price are better tie-breakers than reliability. Sample sizes are shown so you can see which rows are worth weighing.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| United Airlines (this page)thin sample | 133 | 82.8% | 83 min | 3.76% | B− |
| Spirit Airlines | 386 | 80.7% | 87 min | 10.10% | B− |
| Republic Airways | 487 | 76.7% | 88 min | 5.54% | B− |
Spirit Airlines cancels 10.1% 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 is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 133 flights.
- 5am–8am—
- 8am–11am42 flights92.5%
- 11am–2pm60 flights86.4%
- 2pm–5pm31 flights—
- 5pm–8pm—
- 8pm–5am—
Scale runs 80% 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 86.4% on time against 92.5% for 8am–11am. 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 11am–2pm window is the busiest, with 60 flights scheduled in it.
Across the year

- Jul–Sep 202566 flights84.6%

Scale runs 55% 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 82.8% on time across 133 flights.
United on MYR to EWR did not run the same all year. Its best quarter was Apr–Jun 2026 at 97.0% on time and its weakest Oct–Dec 2025 at 63.3%, a swing of 34 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
One category carries most of the weight here. National Airspace System accounts for 57% of the 1,835 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%National Airspace System
- 32%Late-arriving aircraft
- 11%Carrier
57% 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 1,051 minutes out of 1,835, against a national NAS share of 21%. The split is drawn from 1,835 reported delay minutes.
The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 92.5% on time here.
Cancellations run at 3.76%, against 1.81% nationally. That is about one flight in 25 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 costs
8.6% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last an hour and a half, 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. 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 87.8% on time across 133 flights, 5 points above 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 MYR to EWR
Put together: the delay figures matter less here than the 3.76% cancellation rate. A late arrival costs you an hour and a half; a cancelled flight costs you the day. Book the 8am–11am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 128 completed flights over 12 months sit behind that.
