Spirit on EWR to MYR sits in the middle of the pack with a C−. About seven flights in ten arrive on time by the DOT's definition, 7 points worse than the national rate of 77.6%. The late ones land an hour and a half behind schedule. That rests on 382 flights, with a median arrival 9 minutes early.

The national on-time rate over the same period is 77.6%, so Spirit on EWR to MYR runs 7 points behind the country as a whole. Across a thousand flights that is about 71 extra late arrivals.

These figures cover 382 flights between July 2025 and June 2026. Beyond the headline rate, 14.9% 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

Spirit against every carrier on EWR to MYR

Spirit flew 382 of the 1,002 flights on EWR to MYR, about 38% of it. Its 70.5% on time is 8 points worse than the route as a whole, which runs 78.5%. Ranked by on-time rate it is last of three carriers on the route, where the range runs from United at 87.8% to Spirit at 70.5%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.

Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

Departure window

When Spirit 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 half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

  • 5am–8am69 flights88.2%
  • 8am–11am39 flights81.6%
  • 11am–2pm98 flights68.2%
  • 2pm–5pm32 flights
  • 5pm–8pm75 flights61.1%
  • 8pm–5am69 flights59.7%

Scale runs 50% to 95%. Rows with fewer than 30 flights show a dash.

The 8pm–5am window is where this operation falls apart: 59.7% on time, against 88.2% 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 11am–2pm window is the busiest, with 98 flights scheduled in it.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 70.5% on time across 382 flights.

Spirit on EWR to MYR did not run the same all year. Its best quarter was Apr–Jun 2026 at 77.1% on time and its weakest Oct–Dec 2025 at 63.5%, a swing of 14 points on roughly 96 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.

Across the week, Friday is the strongest day at 83.6% on time and Sunday the weakest at 56.9%. 27 points is a smaller lever than departure hour, but it is free.

Delay causes

Why Spirit runs late on this route

One category carries most of the weight here. National Airspace System accounts for 50% of the 9,535 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.

  • National Airspace System
    50%
  • Late-arriving aircraft
    26%
  • Carrier
    19%
  • Extreme weather
    4%
  • Security
    1%

50% 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 4,791 minutes out of 9,535, against a national NAS share of 21%. The split is drawn from 9,535 reported delay minutes.

Cancellations run at 6.81%, against 1.81% nationally. That is about one flight in fifteen 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

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 14.9% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum 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. 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 80.7% on time across 386 flights, 10 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 10 points of difference.

One caution: this is a thin sample. 382 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 Spirit on EWR to MYR

Put together: the delay figures matter less here than the 6.81% cancellation rate. A late arrival costs you an hour and a half; 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. 356 completed flights over 12 months sit behind that.
