You're standing in FLL, maybe grabbing a quick Cuban coffee at Juan Valdez, and you're thinking about the Smokies. It's a weird transition. You go from the humid, salty air of South Florida to the crisp, mountain-adjacent breeze of East Tennessee in just about two hours. But honestly, booking flights from Fort Lauderdale to Knoxville Tennessee isn't always as straightforward as clicking the first "deal" you see on a search engine.
I’ve seen people mess this up constantly. They either overpay for a last-minute connection through Charlotte or realize too late that their "budget" flight lands at an hour when Uber prices to Gatlinburg triple.
The Direct Flight Myth
Most travelers assume that because Fort Lauderdale-Hollywood International (FLL) is a massive hub, there are dozens of daily non-stops to Knoxville’s McGhee Tyson Airport (TYS).
That's not exactly true.
If you want to fly direct, you're basically looking at Allegiant Air. They own this route. For 2026, Allegiant has kept a firm grip on the non-stop market here, often running flights on a specific schedule—think Mondays, Fridays, or Saturdays. If you’re trying to fly out on a Tuesday afternoon, you’re likely going to be looking at a layover.

Southwest has started stepping up their game too. As of early 2026, they’ve introduced more service into Knoxville, but many of those still involve a quick hop through Nashville or Atlanta.
Why the Price Fluctuates So Wildly
You can find a seat for $53 one-way. I've seen it. But three days later, that same seat is $240. Why?
It’s the "Smoky Mountain Effect." Knoxville isn't just a college town for UT Vols fans; it’s the gateway to the most visited national park in America. When leaf-peeping season hits in October or when there’s a massive home game at Neyland Stadium, prices for flights from Fort Lauderdale to Knoxville Tennessee skyrocket.
- Pro Tip: If you see a fare under $110 round-trip on Allegiant, book it. Don't "wait to see if it drops." It won't.
- The Hidden Cost: Remember that Allegiant is a "unbundled" airline. That $53 fare doesn't include a carry-on. By the time you add a bag and a seat assignment, you might be at $130.
- Alternative Hubs: Sometimes it is actually cheaper to fly into Nashville (BNA) and drive three hours, but only if you’re planning a road trip anyway. For a weekend in Knox, just stick to TYS.
Timing Your Arrival at McGhee Tyson
McGhee Tyson isn't in Knoxville. It’s actually in Alcoa.

When you land, you're about 15-20 minutes south of downtown Knoxville. If you’re heading to Pigeon Forge or Gatlinburg, you’re looking at a 45-60 minute drive depending on the nightmare that is Sevierville traffic.
Uber and Lyft are active at TYS, but they aren't as omnipresent as they are at FLL. If you land after 11 PM on a weekday, you might be waiting a bit. Most of the major car rental agencies—Hertz, Enterprise, Budget—are right there in the terminal. It's a small airport. You won't be walking for miles like you do in Terminal 3 at FLL.
Reality Check: The Flight Experience
Expect a flight time of roughly 2 hours and 10 minutes. It’s a short hop. You barely have time to finish a podcast and a snack before you start descending over the Tennessee River.
If you’re flying American Airlines, you’ll almost certainly connect in Charlotte (CLT). Is it worth it? Only if you have status or want the reliability of a legacy carrier. But honestly, for a 700-mile trip, the Allegiant non-stop is hard to beat for pure efficiency. Just bring your own water.

What to Do Once You Land
Don't just rush out of the city. Most people use Knoxville as a pit stop for the mountains, but the Old City area is actually cool.
- Market Square: It’s the heart of the city. Great for people-watching and grabbing a local brew.
- The Sunsphere: Yes, the big gold ball from the 1982 World's Fair. It's iconic. It's also a bit goofy, but you have to see it.
- The UT Campus: Even if you aren't a sports fan, the campus is beautiful.
If you're looking for the best deals on flights from Fort Lauderdale to Knoxville Tennessee, your best bet is to look at the "off-peak" months. April and May are fantastic. The weather in East Tennessee is perfect then—not too humid, everything is blooming, and the flight prices haven't hit the summer peak yet.
Avoid the last two weeks of October unless you want to pay "private jet" prices for a middle seat on a budget airline. Everyone wants to see the leaves change.
Before you click buy, double-check your departure terminal at FLL. Allegiant usually flies out of Terminal 1, while Delta is in Terminal 2 and American/JetBlue are in Terminal 3. It sounds simple, but FLL traffic can be a beast, and ending up at the wrong terminal can cost you twenty minutes you don't have.
To get the most out of your trip, start tracking prices on a Tuesday. Set a Google Flights alert for your specific dates, but keep an eye on Allegiant's own website since they don't always play nice with third-party aggregators. Once you secure that sub-$150 ticket, focus your energy on booking a rental car early; those tend to sell out faster than the flights do during peak hiking season.
