The worst days
Worst days for Spirit on FLL to PIT
The latest arrival of the period was on 21 September 2025, 4 hours 24 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 21 September 2025 | 4 hours 24 minutes | Carrier |
| 25 March 2026 | 4 hours 15 minutes | Carrier |
| 8 September 2025 | 3 hours 50 minutes | Late-arriving aircraft |

Delay causes
Why Spirit runs late on this route
Carrier accounts for 44% of the 8,348 delay minutes carriers reported here, and the remaining four split what is left.

- 32%Late-arriving aircraft

- 2%Extreme weather

The largest share of delay minutes, 44%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 3,707 of the 8,348 delay minutes reported here. The split is drawn from 8,348 reported delay minutes.
The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 85.7% on time here.
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
13.1% 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 994 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 77.0% on time across 407 flights, 8 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 8 points of difference.
One caution: this is a thin sample. 410 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 FLL to PIT
Put together: the delay figures matter less here than the 4.88% 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. 389 completed flights over 12 months sit behind that.
