Carrier by carrier
Spirit against every carrier on BOS to MCO
Spirit flew 389 of the 4,605 flights on BOS to MCO, about 8% of it. Its 58.5% on time is 11 points worse than the route as a whole, which runs 69.5%. Ranked by on-time rate it is number five of six carriers on the route, where the range runs from American at 80.7% to Southwest at 50.0%. Three of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 75.5% of the time; JetBlue Airways manages 66.6%. Sample sizes sit next to every figure, because a two-point gap across 2,520 flights means less than a ten-point one.

JetBlue Airways cancels 3.6% 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 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 27 points, against 9 points between the best and worst carrier.
- 5am–8am29 flights—
- 8am–11am48 flights37.8%
- 11am–2pm114 flights64.9%
- 2pm–5pm161 flights53.9%
- 5pm–8pm23 flights—
- 8pm–5am14 flights—
Scale runs 30% to 70%. Rows with fewer than 30 flights show a dash.
The best window here is not the first bank but the 11am–2pm slot at 64.9% on time, ahead of 8am–11am at 37.8%. Where the curve peaks mid-day rather than at dawn, the constraint is usually congestion at one end rather than the aircraft's own rotation. The 2pm–5pm window is the busiest, with 161 flights scheduled in it.

Share of 369 completed flights by arrival against schedule.
30 of 153 late departures made up the time and arrived on time, 20% of them. In the other direction, 30 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 MCO.
The worst days
Worst days for Spirit on BOS to MCO
The latest arrival of the period was on 28 December 2025, 20 hours 12 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). Three of the five worst days fell in April 2026.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 28 December 2025 | 20 hours 12 minutes | Carrier |
| 9 April 2026 | 8 hours 36 minutes | Carrier |
| 10 April 2026 | 5 hours 58 minutes | Carrier |

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 13,000 reported delay minutes.
- 36%Carrier
- 34%National Airspace System
- 27%Late-arriving aircraft
- 2%Extreme weather
- 1%Security
The largest share of delay minutes, 36%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 4,511 of the 13,000 delay minutes reported here. The split is drawn from 12,554 reported delay minutes.
34% 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 4,326 minutes out of 13,000, against a national NAS share of 21%.
Cancellations run at 4.88%, against 1.89% nationally. That is about one flight in twenty 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
19.2% 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 1,121 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 70.1% on time across 392 flights, 12 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 12 points of difference.
One caution: this is a thin sample. 389 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 BOS to MCO
Put together: the delay figures matter less here than the 4.88% cancellation rate. A late arrival costs you an hour and a half; a cancelled flight costs you the day. Book the 11am–2pm departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 369 completed flights over 12 months sit behind that.
