What the record says about this route
The season swings this route hard. In October it ran 31 points more punctual than in March — a difference bigger than the one between the best and worst airlines on most routes. If the date is flexible, it is worth more than the carrier.
The shape of the lateness matters here. Flights on this route are not late often, but when they are late they are late by about 81 minutes — long enough to lose a connection or an evening. The on-time percentage looks reassuring and understates the consequence of being on the wrong flight.
The route has been getting worse. The later months run 11 points less punctual than the earlier ones. A drift of that size is rarely weather; it is more often an airline adding frequencies faster than the airports can absorb them.
This route does better than its own airport. Departures from FLL overall run 8.3 points less punctual than this particular one — so whatever congestion FLL has, this route is largely escaping it.
Which airline should you fly on this route?
Over July 2024 – July 2026, Delta Air Lines arrived on time most often on FLL to SLC. Flights ran closest to schedule in November and worst in February.

What these figures do and do not tell you
Everything on this page is counted from the flights that actually operated on FLL to SLC during July 2024 – July 2026, as reported by the airlines to the US Bureau of Transportation Statistics. "On time" is the federal definition: arriving at the gate within 15 minutes of the scheduled time.
A route's record is a description of the past, not a forecast. Weather, air traffic control and the aircraft's earlier flights that day drive most delays, and none of them are predictable from a historical rate. What the record does tell you is whether this route runs late more often than others, and which carrier on it has the better history — which is the part you can actually act on when you book.
Cancellations are counted separately from delays because they are a different problem for a traveller: a late flight still gets you there. How the grade is calculated →
