Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with Spirit Airlines.
Spirit on MYR to EWR lands a B−, 4 points better than the national rate of 77.3%. About one flight in five arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That rests on 296 flights, with a median arrival 12 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate Spirit on MYR to EWR from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Carrier by carrier
Spirit against every carrier on MYR to EWR
Spirit flew 296 of the 916 flights on MYR to EWR, about 32% of it. Its 80.8% on time is about level with the route as a whole at 80.4%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from Spirit at 80.8% to Republic at 80.1%. 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 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 296 flights.
- 5am–8am51 flights86.4%
- 8am–11am111 flights81.7%
- 11am–2pm80 flights76.7%
- 2pm–5pm13 flights—
- 5pm–8pm13 flights—
- 8pm–5am28 flights—
Scale runs 70% to 90%. 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 76.7% on time against 86.4% 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 111 flights scheduled in it.

| Date | Arrived late by | Largest filed cause |

Delay causes
Why Spirit 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 4,792 reported delay minutes.
- 41%Late-arriving aircraft
- 38%National Airspace System
- 21%Carrier
- 0%Extreme weather
41% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,792 reported delay minutes here, that single category outweighs weather by 41 to one. The split is drawn from 4,792 reported delay minutes.
38% 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 1,816 minutes out of 4,792, against a national NAS share of 21%.
Cancellations run at 12.16%, against 1.89% nationally. That is about one flight in eight 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
11.5% 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 is a different operation and performs like one: it runs 70.8% on time across 293 flights, 10 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 10 points of difference.
One caution: this is a thin sample. 296 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 MYR to EWR
Put together: the delay figures matter less here than the 12.16% 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. 260 completed flights over 12 months sit behind that.
