Flying from Fort Lauderdale to Knoxville: what you need to know
The flight
The nonstop from FLL to TYS runs about 1h 57m over 710 miles. It's a comfortable mid-range flight: long enough that seat choice matters a little, short enough that paying up for extras rarely does.
Airlines on this route
Allegiant Air flies this route nonstop. That matters more than it sounds: the cheapest fare on one carrier is rarely the same product as the cheapest on another. Checked-bag fees, free seat selection and change rules all differ, so compare the full trip cost before you pick a winner. See our airline guides for exactly what each carrier charges — then send an enquiry and we'll confirm the all-in price for your dates.
Leaving from Fort Lauderdale (FLL)
Plan to be at the airport two hours before a domestic departure — ninety minutes can work at smaller airports outside peak times, but security lines are the one variable you can't control. If you're checking a bag, add time rather than cutting it close. Our Fort Lauderdale airport guide covers terminals, parking and ground transport so you can plan the trip to the airport, not just the flight.
Arriving in Knoxville (TYS)
Before you land, know how you're getting from the airport to where you're staying — it's the part of the trip people forget to plan. The Knoxville airport guide lays out your ground options, from transit and shuttles to rideshares and rental cars. Flying back the other way? Check Knoxville to Fort Lauderdale fares — prices on the return direction often move on a different rhythm.
When to book
For a trip of 710 miles, booking 2–4 weeks ahead typically lands you in the sweet spot. Leave it to the final two weeks and prices usually climb as the cheapest seats sell out. If your dates are flexible, midweek departures are where the lower fares hide on most domestic routes.
Good to know before you go
- Basic economy fares often exclude checked bags and seat selection. Price the whole trip, not the headline fare.
- Get to the airport two hours before departure; security, not the flight, is the part that runs late.
- If you're traveling with only a carry-on, you can skip the bag-drop line entirely with mobile check-in.
- Download the airline's app before you fly; gate changes and delays show up there first.
- Nonstop time on this route is about 1h 57m — a one-stop itinerary needs to be a lot cheaper to be worth the extra hours.
