You’re sitting in Hartsfield-Jackson, probably near Terminal T or A, nursing a lukewarm coffee. You’ve got that "I need a vacation" itch. Key West sounds perfect. It is. But honestly, the process of getting flights Atlanta to Key West FL is where most people trip up before they even see a palm tree.
It’s only about 650 miles. You could drive it, sure. But that’s 14 hours of pavement and the potential madness of the Florida Turnpike. Flying is the move.
The thing is, people assume a "short" flight means a simple booking. It’s not. Between the weird pricing cycles, the tiny runway at EYW that limits plane sizes, and the fact that one specific airline basically owns this route, there’s a lot to navigate.
The Delta Monopoly (and Why It Matters)
Let’s be real: if you want to fly direct, you’re flying Delta.

They are currently the only carrier running nonstop service from ATL to EYW. Usually, they run about three to four flights a day. The flight time is a breeze—usually clocked at 1 hour and 55 minutes, though if the tailwinds are behaving, you might touch down in 1 hour and 45.
Because Delta has the "only direct" card, they play it hard. Prices for these seats fluctuate like crazy. I’ve seen them for $300 round-trip on a random Tuesday in October, and I’ve seen them hit $850 for a holiday weekend.
If you aren't loyal to the Widget, you have options, but they come with a catch. American, United, and even Spirit will take you there, but you’re going to sit in Charlotte, Miami, or Fort Lauderdale for a few hours.
Is the "Budget" Route Actually Worth It?
Spirit and Frontier often pop up on search engines with prices like $64 one-way. Sounds like a steal, right?

Kinda.
Most of these budget flights Atlanta to Key West FL involve a connection in Fort Lauderdale (FLL). By the time you pay for a carry-on bag—which Spirit loves to charge $50+ for—and spend 6 hours traveling instead of 2, that $300 Delta flight starts looking like a bargain.
Also, consider the "Silver Airways" factor. You might see a flight marketed by United or JetBlue that is actually operated by Silver Airways. They fly Saab 340s or ATR-600 turboprops.
It’s a different experience. It’s loud. It’s shaky. Some people love the old-school island hopper vibe. Others? Not so much. If you’re a nervous flier, stick to the Delta Airbus A319s.
When to Pull the Trigger on Tickets
Timing is everything. 2026 data shows that January is consistently the cheapest month to fly this route. You can find round-trips for under $200 if you’re flexible.
But Key West in January is "chilly" for locals (meaning 65°F). If you want the classic 80-degree weather, March through May is the sweet spot. Just be prepared to pay the "Spring Break Tax."
- Book 40 days out: This is the statistical "sweet spot" for domestic Florida flights.
- Check Tuesdays: For some reason, the ATL-EYW leg stays cheaper if you fly mid-week.
- The "Skiplagging" Warning: Don't try to book a flight to Miami and just hop out if you have checked bags. Key West is its own beast, and the airlines monitor this route heavily.
The Landing: Why EYW Is Not Your Average Airport
Key West International (EYW) has a notoriously short runway.
It’s about 5,000 feet. For context, the runways at ATL are twice that. This means pilots have to be precise. It also means that in the summer, when the air is hot and thin, planes sometimes have "weight restrictions."
I’ve seen instances where the airline has to bump a few passengers or pieces of luggage because the plane is too heavy to take off safely in the heat. It’s rare, but it happens.

Once you land, don't expect a massive terminal. It’s charmingly small. You’ll walk off the plane, breathe in that salt air, and be at the luggage carousel in five minutes.
Getting to Your Hotel
Don't bother with a rental car. Seriously. Key West is four miles long. Parking is a nightmare and costs a fortune.
- Taxis: There’s a flat-rate zone system. If you’re heading to the historic district (West of White Street), it’s usually about $9 per person.
- Rideshare: Uber and Lyft operate here, but they can be spotty during peak "Duval Crawl" hours.
- Shuttles: Many resorts like the DoubleTree or Havana Cabana offer free pick-ups. Call them before you board in Atlanta.
Beyond the Ticket: Practical Insights
If you’re looking for the best value, aim for the first flight of the morning. The 8:15 AM Delta departure is usually the most reliable. Afternoon storms in Florida are a daily occurrence in the summer, and EYW doesn't handle delays well—the gate space is limited.
Also, keep an eye on bag sizes. The overhead bins on the regional jets that often service this route (even the Delta ones) are smaller than the "Big Birds" you see on transcontinental flights. If your "carry-on" is a massive hardshell suitcase, expect to gate-check it.
Key West is one of the most unique spots in the US. Getting there from Atlanta is a privilege of living near a major hub, provided you don't overpay for the convenience.
