You’re standing in the middle of Logan Airport, iced coffee in hand, staring at the departure board. You want to get to the Smokies, but for some reason, finding a straightforward way to Tennessee feels like solving a riddle. Most people assume they’ll have to suck it up and spend six hours in a terminal in Charlotte or Atlanta.
Honestly? You don’t always have to.
Getting flights from Boston to Knoxville Tennessee is a weirdly specific travel challenge. Knoxville isn’t a massive hub like Nashville, so McGhee Tyson Airport (TYS) doesn’t get the constant stream of direct heavy-hitters you’d expect for a city of its size. But if you know how to time it, you can skip the layovers entirely.
The Myth of the "Only One Way" Connection
Standard travel sites will scream at you that Delta or American is your only choice. And sure, they fly there constantly. You can hop a Delta flight through Atlanta or an American flight through Charlotte basically every hour.
But here’s the kicker: Allegiant Air.
They are the only carrier that currently runs nonstop service between BOS and TYS. It’s a game-changer. Instead of a five-hour ordeal, you’re on the ground in about 2 hours and 30 minutes. The catch? They don't fly every day. Usually, it's a Sunday, Monday, Wednesday, Friday kind of deal. If your schedule is rigid, you're stuck with a layover. If you're flexible, you save half your day.

Navigating the Big Three
If you can’t catch that direct flight, you’re looking at the legacy carriers.
- American Airlines: They own the Charlotte (CLT) connection. It's usually the fastest "one-stop" option. You’re looking at about 4 hours and 50 minutes total travel time.
- Delta: You’ll almost certainly go through Atlanta (ATL) or Detroit (DTW). ATL is a beast of an airport, so give yourself at least an hour between gates.
- United: These routes typically filter through Dulles (IAD) or Chicago (ORD).
Southwest has also entered the ring more aggressively recently. They’ve started offering more service into Knoxville, often connecting through Nashville (BNA) or Baltimore (BWI). It's worth checking because of the "two bags fly free" rule, which is a big deal if you're bringing hiking gear for the national park.
Scoring a Deal Without Losing Your Mind
Prices for this route fluctuate like New England weather. One day it’s $116 round trip; the next, it’s $450 for a basic economy seat where you can’t even bring a backpack.
February is, statistically, the cheapest month to fly this route. It makes sense. It’s cold in Boston and it’s chilly in Knoxville. But if you’re heading down for the spring wildflowers in the Smokies or a Vols game in the fall, expect those prices to double.
Pro tip: Book on a Sunday. Data from the ARC suggests that booking domestic flights on a Sunday can save you about 10% to 15% compared to booking on a Friday. Also, Wednesday is usually the cheapest day to actually get on the plane.

What to Expect at McGhee Tyson (TYS)
When you finally land, don't expect a massive, sprawling complex. TYS is refreshing. It’s small, easy to navigate, and honestly, kinda charming with its rocking chairs.
It’s located in Alcoa, about 12 miles south of downtown Knoxville.
- Uber/Lyft: Usually plenty of drivers. Expect to pay $25–$40 to get to Market Square.
- Rental Cars: All the majors are there (Hertz, Enterprise, Avis). If you're going to the mountains, you need a car. Public transit to Gatlinburg isn't really a thing from the airport.
The Seasonal Trap
People forget that East Tennessee has actual seasons. If you’re flying down in October to see the leaves change, you are competing with every other person on the East Coast. Flights will be packed.
Conversely, if you fly in late July, it is going to be humid. Not "Boston humid," but "I am breathing soup" humid. Plan your wardrobe accordingly. Logan Airport is great for winter departures because they handle snow better than almost anyone, but a summer thunderstorm in Charlotte can delay your connection for hours.
Is it Worth Driving?
Some people look at the $400 ticket and think, "I'll just drive."

Don't.
It’s roughly 900 miles. That’s 14 hours of pure driving, not counting traffic on I-95 or the inevitable construction in Pennsylvania. Unless you’re moving your entire life in a U-Haul, the flight is always the better move. Even a $300 ticket is cheaper than the gas, tolls, and the hotel stay you'll need halfway through Virginia.
Making the Most of the Trip
Once you’ve sorted your flights from Boston to Knoxville Tennessee, have a plan for when you land. If you arrived on a direct Allegiant flight, you probably have some extra energy.
- Head to Market Square: It’s the heart of the city. Great food, street performers, and very walkable.
- The Sunsphere: You saw it on The Simpsons, now go up in it. It’s free (usually) and gives you a 360-degree view of the city and the mountains.
- UT Campus: Even if you aren't a sports fan, the University of Tennessee campus is beautiful and right on the river.
Your next move: Check the Allegiant schedule first to see if their direct flight days align with your trip. If they don't, set a price alert on Google Flights for American and Delta. Look for connections in Charlotte specifically, as they tend to have the shortest layovers for this specific New England-to-South route.
