Carrier by carrier
Frontier against every carrier on BOS to MCO
Frontier flew 151 of the 4,605 flights on BOS to MCO, about 3% of it. Its 74.0% on time is 5 points better than the route as a whole, which runs 69.5%. Ranked by on-time rate it is number three of six carriers on the route, where the range runs from American at 80.7% to Southwest at 50.0%. Two 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; Spirit Airlines manages 58.5%. Sample sizes sit next to every figure, because a two-point gap across 389 flights means less than a ten-point one.

Spirit Airlines cancels 4.9% 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 Frontier runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 14 points, against 17 points between the best and worst carrier.
- 5am–8am—
- 8am–11am89 flights79.8%
- 11am–2pm62 flights65.6%
- 2pm–5pm—
- 5pm–8pm—
- 8pm–5am—
Scale runs 55% to 85%. 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 65.6% on time against 79.8% for 8am–11am. 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 89 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 74.0% on time across 151 flights.
Frontier on BOS to MCO did not run the same all year. Its best quarter was Jul–Sep 2026 at 85.2% on time and its weakest Oct–Dec 2025 at 48.5%, a swing of 37 points on roughly 50 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.
Arrival by arrival
How late Frontier on BOS to MCO runs when it is late
Frontier on BOS to MCO often beats the schedule: 55 of 150 completed flights, 37%, arrived 15 minutes or more early. The 39 late arrivals split 9 under half an hour, 15 between 30 and 60 minutes, and 15 an hour or more.

Share of 150 completed flights by arrival against schedule.
A late pushback is often recovered here: of 41 departures that left 15 minutes late or more, 14 still arrived on time. In the other direction, 12 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 Frontier on BOS to MCO
The latest arrival of the period was on 8 November 2025, 6 hours 15 minutes behind schedule; most of its delay minutes were filed as national airspace system delay. The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 8 November 2025 | 6 hours 15 minutes | National Airspace System |
| 30 July 2026 | 3 hours 23 minutes | National Airspace System |
| 23 December 2025 | 3 hours 21 minutes | Late-arriving aircraft |

Delay causes
Why Frontier runs late on this route
National Airspace System accounts for 50% of the 2,853 delay minutes carriers reported here, and the remaining four split what is left.
- 50%National Airspace System
- 33%Late-arriving aircraft
- 15%Carrier
- 2%Extreme weather
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 1,428 minutes out of 2,853, against a national NAS share of 21%. The split is drawn from 2,853 reported delay minutes.
The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 79.8% on time here.
Cancellations are rare at 0.00%, below the national 1.89% and low enough to earn the plus on the grade. Almost no flights are called off; the risk here is arriving late, not not arriving.
Connections and stage length
What a delay here costs
10.0% 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 90.7% on time across 151 flights, 17 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 17 points of difference.
One caution: this is a thin sample. 151 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 Frontier on BOS to MCO
Put together: treat all of this as provisional. 151 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 74.0% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 150 completed flights over 12 months sit behind that.
