Carrier by carrier

Frontier against every carrier on LGA to MCO

Frontier flew 339 of the 5,149 flights on LGA to MCO, about 7% of it. Its 56.1% on time is 14 points worse than the route as a whole, which runs 70.1%. Ranked by on-time rate it is last of five carriers on the route, where the range runs from Spirit at 75.2% to Frontier at 56.1%.

The choice of carrier is not cosmetic here. Spirit Airlines arrives on time 75.2% of the time; JetBlue Airways manages 68.0%. Sample sizes sit next to every figure, because a two-point gap across 1,206 flights means less than a ten-point one.

The 8pm–5am window is where this operation falls apart: 50.3% on time, against 66.4% for the 11am–2pm 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 8pm–5am window is the busiest, with 185 flights scheduled in it.

Share of 314 completed flights by arrival against schedule.

22 of 143 late departures made up the time and arrived on time, 15% of them. In the other direction, 17 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.

Delay causes

Why Frontier runs late on this route

Late-arriving aircraft accounts for 62% of the 17,000 delay minutes carriers reported here, and the remaining four split what is left.

Carrier

Extreme weather

62% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 17,000 reported delay minutes here, that single category outweighs weather by 42 to one. The split is drawn from 17,475 reported delay minutes.

Cancellations run at 7.37%, against 1.89% nationally. That is roughly one flight in fifteen 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

20.7% 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 950 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 68.8% on time across 338 flights, 13 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 13 points of difference.

One caution: this is a thin sample. 339 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 LGA to MCO

Put together: the delay figures matter less here than the 7.37% cancellation rate. A late arrival costs you about 2.1 hours; 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. 314 completed flights over 12 months sit behind that.
