Carrier by carrier
Spirit against every carrier on EWR to MYR

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 25 points, against half a point between the best and worst carrier.

- 8am–11am29 flights—
- 11am–2pm93 flights69.9%

Scale runs 50% to 90%. Rows with fewer than 30 flights show a dash.
The 8pm–5am window is where this operation falls apart: 58.6% on time, against 83.7% 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 93 flights scheduled in it.

Share of 271 completed flights by arrival against schedule.
14 of 78 late departures made up the time and arrived on time, 18% of them. In the other direction, 15 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at MYR.
The worst days
Worst days for Spirit on EWR to MYR
The latest arrival of the period was on 18 March 2026, 5 hours 33 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The five worst days are spread across March, December, November and September, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 18 March 2026 | 5 hours 33 minutes | Carrier |
| 2 December 2025 | 4 hours 48 minutes | National Airspace System |
| 23 November 2025 | 4 hours 9 minutes | Late-arriving aircraft |

Delay causes
Why Spirit runs late on this route
National Airspace System accounts for 43% of the 6,329 delay minutes carriers reported here, and the remaining four split what is left.
- 43%National Airspace System
- 35%Late-arriving aircraft
- 18%Carrier
- 3%Extreme weather
- 1%Security
35% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 6,329 reported delay minutes here, that single category outweighs weather by 10 to one. The split is drawn from 6,329 reported delay minutes.
43% 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 2,725 minutes out of 6,329, against a national NAS share of 21%.
Cancellations run at 7.51%, against 1.89% nationally. That is roughly one flight in twelve 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
13.3% 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 80.8% on time across 296 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. 293 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 7.51% 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. 271 completed flights over 12 months sit behind that.
