Carrier by carrier
Spirit against every carrier on MCO to BOS
Spirit flew 392 of the 4,614 flights on MCO to BOS, about 8% of it. Its 70.1% on time is about level with the route as a whole at 71.1%. Ranked by on-time rate it is number four of six carriers on the route, where the range runs from Southwest at 100.0% to American at 66.8%. 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 77.0% of the time; JetBlue Airways manages 67.4%. Sample sizes sit next to every figure, because a two-point gap across 2,527 flights means less than a ten-point one.

JetBlue Airways cancels 3.7% 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 34 points, against 10 points between the best and worst carrier.

- 8am–11am137 flights69.9%
- 11am–2pm39 flights86.1%

Scale runs 45% to 95%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 89.3% of the time, against 55.4% for the afternoon window. That is 34 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8am–11am window is the busiest, with 137 flights scheduled in it.

Share of 374 completed flights by arrival against schedule.
14 of 97 late departures made up the time and arrived on time, 14% of them. In the other direction, 29 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 BOS.

The latest arrival of the period was on 29 March 2026, 3 hours 53 minutes behind schedule; most of its delay minutes were filed as national airspace system delay. Three of the five worst days fell in March 2026.

Delay causes
Why Spirit runs late on this route
National Airspace System accounts for 55% of the 6,091 delay minutes carriers reported here, and the remaining four split what is left.
- 55%National Airspace System
- 31%Carrier
- 13%Late-arriving aircraft
- 1%Extreme weather
55% 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 3,323 minutes out of 6,091, against a national NAS share of 21%. The split is drawn from 6,091 reported delay minutes.
Cancellations run at 4.59%, against 1.89% nationally. That is roughly 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
9.9% 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 58.5% on time across 389 flights, 12 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 12 points of difference.
One caution: this is a thin sample. 392 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 MCO to BOS
Put together: the delay figures matter less here than the 4.59% cancellation rate. A late arrival costs you about 55 minutes; 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. 374 completed flights over 12 months sit behind that.
