FAQs - booking Florida Keys flights

  • Which Key should I travel to for the best beaches?

    Key West has the best beaches. The closest beach to the Key West International Airport is Smathers Beach, which is 3m away by car and 13m by bus on the blue route. A one-way bus ticket costs around $2.

  • How do I travel from the airport to Hemingway House in Key West?

    The Hemingway House in Key West is about 4 mi from the airport. You can take the Key West Transit bus blue route from the Key West International Airport. The trip takes about 30m, and a one-way ticket costs approximately $2. The fastest way is to rent a car at the airport and drive there yourself, or you can get a rideshare service (about $15).

  • I’m traveling with my family to Florida Keys. Which Key is the most kid-friendly?

    If you’re traveling with kids to Florida Keys, you’ll want to avoid Key West. It’s typically more crowded, and the nightlife is a bit noisier than the rest of the Keys. You can travel to Miami International Airport and drive to Key Largo to use as your base. If you don’t want to stay only in one spot, then from Key Largo you’re just a short drive from two other calm and worthwhile Keys—Islamorada (27m) and Duck Key (56m).

  • Which Key is closest to the Bahia Honda State Park?

    Marathon is the Key closest to Bahia Honda State Park (15 mi). If you’re planning on choosing another place to stay while in the Florida Keys, Key West is 35 mi from the State Park, and Key Largo is 62 mi from the park.

  • Where should I travel to stay close to the Dry Tortugas National Park?

    Key West is the closest key to Dry Tortugas National Park, so you should travel directly to the Key West International Airport. Key West is 2h 15m from the park by ferry.

  • How does KAYAK find such low prices on flights from the United States to Florida Keys?

    KAYAK is a travel search engine. That means we look across the web to find the best prices we can find for our users. With over 2 billion flight queries processed yearly, we are able to display a variety of prices and options on flights from the United States to Florida Keys.

  • How does KAYAK's flight Price Forecast tool help me choose the right time to buy my flight ticket from the United States to Florida Keys?

    KAYAK’s flight Price Forecast tool uses historical data to determine whether the price for a flight from the United States to Florida Keys is likely to change within 7 days, so travelers know whether to wait or book now.

  • What is the Hacker Fare option on flights from the United States to Florida Keys?

    Hacker Fares allow you to combine one-way tickets in order to save you money over a traditional round-trip ticket. You could then fly from the United States to Florida Keys with an airline and back with another airline.

  • What is KAYAK's "flexible dates" feature and why should I care when looking for a flight from the United States to Florida Keys?

    Sometimes travel dates aren't set in stone. If your preferred travel dates have some wiggle room, flexible dates will show you all the options when flying from the United States to Florida Keys up to 3 days before/after your preferred dates. You can then pick the flights that suit you best.

  • The Key West International Airport is small and easy to navigate, so all the services you need are located in the same area as the baggage claim. Those include car rental companies, ATMs, and ground transportation information booths.
  • Travelers going to Key Largo might not want to drive the 97 mi from Key West on the other end. Alternatively, you can look for flights to Florida Keys that stop at Miami International Airport (MIA) and take the door-to-door shared shuttle bus from the airport to your hotel in Key Largo, which costs about $60 per person.
  • For passengers with children, the Key West airport doesn’t have many food and restaurant options. If you need to grab some snacks for your kids before heading downtown, the nearest supermarket is 10m from the airport.
  • If you’re traveling with pets, please keep in mind when booking your flight to Florida Keys that Key West International Airport is not equipped with pet relief areas. The closest airport to the Florida Keys with such facilities is the Miami International Airport.

Great service. Great staff. Boarding was a little slow, but I think there was a service dog slowing things down.

Great service. Great staff. Boarding was a little slow, but I think there was a service dog slowing things down.

Other then mechanical/ computer problem and 3.5 hours flight delay the flight was great. I guess that what happened when you fly an old airplane now a day.

This was a code share Latam Airlines flight - everything very good except there was no seatback entertainment

Don't waste your money or points on first class. Delta first class is a joke. The seats were rickety, the food was awful, and nothing worked, wifi, my light, the power plug - and it was dirty - the fold out table was gross. For 2-3 hours, tough it out in Economy.

Loyal Delta traveler, but last nights flight was a train wreck. Seated in 1B after multiple delays. Then we couldn’t takeoff because of an issue with the passenger that was ‘not in compliance’ and had to deplane along with the threat if they did not deplane, all the passengers would be required to do so. Finally they were escorted off, but the experience threw off the crew. Disruptive for everyone. Service was a mess, televisions didn’t work, bathroom door kept swinging open during the entire flight whenever empty …

My flight was cancelled twice and the third time I tried to rebook it online I cancelled the flight because it looked like I would get a refund to my credit card. Instead I now have a credit. I was also on hold for three hours waiting for a representative and then disconnected. I will never fly delta again.

Awful. Flight was continuously getting delayed and gates kept changing without any reason. Flight was delayed for more then 3 hours

5-hour delay due to storms in Tanoa and airspace restricted by Miami traffic controllers.

I would fly again the whole experience was great. The only feed back I can give that they don't do that American Airlines does is the crew there is more humorous with boarding and thank their passengers. It makes it more fun to fly with them. I would however fly Delta again.

Horrible. This was not first class. This was a connecting flight whi h was late. My original flight never came. I hated the fact that delta gave me a connecting flight from New York to Orlando Florida. No meals and the television screens were not working. There wasn't even any power to charge your phones. This is NOT FIRST CLASS DELTA!!! Do better next time!

I liked all the informational texts. I always knew where to go and when .

Liked the hospitality . The ight took us 6 hrs to get from fort myers to ewr.

Oh my gosh, I loved my experience with United! they made me want to travel more often.

The flight attendants in First Class were mediocre at best. They did not take our tray away until we were about to land and only did so when I press the call button. The United person at the United Club was asked to get us our boarding pass since we missed the flight due in Chicago. She argued that we did not have seats on the flight given to us in Moline. Furthermore, she was adamant that we did not have a First Class ticket. After I spent much time with her trying to show we were correct, she reluctantly agreed. She was probably the most incompetent ticketing person I have ever met and I have traveled 3 million miles on United plus many additional miles with other carriers. United has definitely deteriorated in more than on way.

The plane was in Moline all night. Consequently, we assumed an on time departure at 8:15am. Unfortunately, and as is the normal case with United in Moline, we departed 2.5 hours late. When the crew came, it was discovered that there was very little heat in the plane. Seems this should have been checked hours before the crew arrived. Then when we boarded and the plane was to be de-iced, the United de-icing truck was not working! We awaited the American Airlines truck. All of this caused us to miss our connection in Chicago. My suggestion is never take United Airlines flight from Moline. We have been disappointed 80% of the time and have vowed to not take United again from Moline.

Flight was delayed two hours. No snacks and no tv screens. My bag got stuck in Chicago

Awful. Worst airline I have ever been on. Crew were among the rudest people I have ever dealt with. United staff members were rude and disrespectful. My flight was delayed, causing me to miss a connecting flight. I understand things happen, but when staff start lying about what actually happened, that is when I have an issue. Just be honest, really it isn’t that hard. I’m being very honest with this review and I don’t find this difficult what so ever. In fact, because of United Airlines, my Christmas holiday was off to a really rocky start. As someone who has traveled across the world, it has only been United that I have had a truly awful experience.

Received an email the night before showing that there would be seatback entertainment on our flight. We get on and there was no seatback entertainment. And then it was a scramble to try to set up the iPads for the kids before takeoff so they could watch something for the four hour flight.

The aircrew was solid, the flight was chill, I had no issues. The gate agent was not the best. I was trying to use a military bag upgrade to move my bag from under the seat to the overhead bins and he told me there’s no overhead bins on the plane, argued with me why booking put a military member in basic economy (I don’t really understand this) and made it an issue to even try to help me stating I’d have to call reservations to get a bag upgrade. When every other agent with United can add it at the gate, this man couldn’t be bothered.

Short flight - no food understandable. Flight was delayed for over an hour. Overall, it was good.

I had a very unpleasant encounter with one man from customer service: he was extremely rude and miserable. And his condition was reflected on his decision to send me to the worst airport hotel and get an awful flight connection. My hotel shuttle had never arrived and I had to book another hotel. People served by other representatives got a much better treatment and deal.

Very mediocre greeting as we boarded, and the lead flight attendant accent was almost unrecognizable. He joked around a lot, while trying to give the safety demonstration, but did not succeed. My wife’s row was completely missed for beverages and the lead flight attendant didn’t even know that our row was Main cabin and able to have beverages at no charge. We are platinum, 2,000,000 miles on American Airlines and this was not a stellar crew.

Two issues. The plane was old and dirty. The armrest looked like an old car that had the vinyl rubbed off. The Seats in these aircraft are about as hard and uncomfortable. I want to tour Italy for a month and I want to buy a one-way ticket to Thailand but I will not sit in the seats these planes have. It is seriously stupid how hard they are.

The flight left a bit late, but arrived close to time expected…With the flight being close to full the crew did well serving drinks to all in a very timely fashion. The flight was a pleasure…

Check bag location is full of rude employees who are unwilling to assist with issues after talking to AA on the phone and relaying messages. The boarding was good. While on the flight it got really hot. Asked flight attendant if there’s a way to drop the temp and make it more comfortable as we are flying from DC to Miami so flying from cold to hot weather. No changes made. Stayed hot and uncomfortable on the plane. When asked again about the AC being down the flight attendant said no the WiFi was down but not the AC. I mentioned it was still hot. No changes.

There was a delay that affected all passengers with connecting flights.

Missed our connector because our first flight was delayed, it was a miracle that we managed to get a second flight. Luggage was lost. People were rude. Flight was delayed and overbooked. Terrible experience. Worst flight I’ve ever had out of hundreds of domestic and international flights. I’ve been on a more comfortable 20 hour flight from Guam than the two hours it took NC TO FL.

Great flight from Charlotte to Orlando. In flight wifi and entertainment was not working til 25 minutes were left in the flight would be my only complaint.

I love to flight american however my carry on had to be sent with regular luggage and it was broken. Don't appreciate that. If when I buy a ticket says I can take a carry on and a hand item there should be space for mwsy stuff and not be basically forced to send the item even if it's at no charge. A.A. needs to work on that. Everything else excellent.

One of the reasons I fly American is because the seating is more comfortable than most airlines. Even in the back of the plane.

The ticket agent wouldn't check our bags, eventhough the flight was delayed and wouldn't board for another hour. The gate agents were only mildly better than the ticket agent. They also had a terrible attitude and work ethics.

we are al people and we go through stuff so my scale is only how i felt, I understand we are all humans, i would definitely ride with soirit again, people in orlando are very helpful which makes it all the better .

My flight was arbitrarily changed from 6:00 AM to 5:10 AM ... One less hour of sleep after Christmas Eve, NOT very thoughtful, Oh, and I could not get a refund!!! I paid extra for a front seat and WIFI, there's was NO WIFI (flight 993 Dec 25). Why do you call what you offer FOOD? Would you feed your kids this stuff when you are trapped inside a steel tube for Hours??? Will I get a refund?

Try bad experience. The flight took off leaving behind everyone’s baggage and to top it off the captain nor the crew bothered letting anyone know about this and instead asked us that the baggage can be claimed from carousel 13 when the flight didn’t have even a single baggage. Furthermore they let everyone stand around the carousel for 1 hour to finally let people know that no baggage were loaded onto the flight.

Lost MacBook, had time to retrieve, but was told I had no time. Need Silver MacBook back

I did not fly Spirit. Connie fraudulently used my email to book her flight. I do not know Connie!

Terrible all around. Not much else to say, other than an awful experience from start to finish.

Helpful attendants at check-in is very good. The $70 charge for a checked bags I didn't care for.and the constant charges for picking a seat and faster check-in are too much. Please cut the prices by at least 50% would be fantastic!

The MOST uncomfortable seat I've EVER experienced on ANY airlines. My wife & I were in agony at the end of the flight. NEVER AGAIN!

The flight was delayed over an hour and we had to sit on the plane. Crew does not apologize due to the delay. Spirit will NEVER do anything to give a customer a better experience. A child next to me was kicking me the whole time. I don't ever enjoy flying with Spirit.

Our flight was suppose to leave at 9pm and we didn’t board until after 3am. We lost a whole day at our hotel and half a day at a park we paid a lot of money for.

Boarding was organized and flight was on time. Overall very satisfied with my flight.

The boarding gate was in Terminal D, but the Frontier counter was in Terminal E. So I had to move back and forth between terminals to check in my luggage. This was the worst experience that I had in terms of flights.

Booked direct in July '24. Turned into a 14 hr layover (both ways) in Denver. My 5 day vaca turned into a 1 day . Not good, BUT,... Thank you for the people @ Frontier who were professionally friendly & approachable.

Airline changed the gate from Terminal A to Terminal D which is quite far and only sent a text message few minutes before boarding. Around 50 people missed their flight and as plane didn’t wait for them.

The personal at boarding are rude and try to steel people with their rule of personal item , really bad experience for us

I did not like that people are purposely split ip who book at the same time because we didn’t buy seats. No other airline does that.

Horrible my trip was delayed 3 hours, we already have set in the plane and they delayed the flight.

Checking in was easy and simple, crew was nice and efficient, but I would improve seat assignment randomness to make it easier to sit together based on when you check in. Overall would fly with them again.

It was delayed 9 hours for operational reasons, despite the plane arriving to the airport on time.
