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?

  • 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?

  • 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.

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.

Boarding is, as it always is… horrible. Gate lice. Slow moving zones. Too many people with carry ons

Boarding is, as it always is… horrible. Gate lice. Slow moving zones. Too many people with carry ons

I loved having a most black flight crew during Black History Month; rather by design or accident I appreciated the representation. ❤️

This was the second flight this week with flight attendant Marcus I’m not sure if his last name is Lane or Lang but this guy is awesome. He funny, attentive and his service is 5 stars. Marcus makes business travel more enjoyable !

Although the flight left late, we arrived early. It was one of the quickest boarding and off boarding experiences I’ve had. It was kind of annoying the only drinks they had were water, coffee, and tea. The flight was very smooth, temperature was just right, and flight attendants were friendly.

Lower number on this flight so spaced out passengers. Able to enjoy more room to relax during flight. It was lovely.

Kind staff. Snacks are small but that’s the new normal.

The young man who was our flight attendant in first class was lazy and did not do his job well at all. Never offered drinks upon boarding - actually I take that back... said "are you okay with water" as if I do not want to get you anything else, only passed the snacks around once, got my drink order wrong and then never offered a second round of drinks. He was the worst I have ever seen on Delta and we fly a lot.

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

Flight left early and arrived early. the whole trip was excellent.

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.

I don’t understand the purpose of the orange “priority” tag on my bag. This tagged, my bag is last or near to the last bag to come down the carousel at IAH.

The tv monitor in front of my seat was not responding. The flight crew reset it and it still didn’t work.

The agents was very rude and they charged me $50 for a carry-on bag saying that it was too big and then I saw someone going on a plane with the same size bag as me

Terrible. First of all we were delayed 4 3/4 hours departing Honolulu. As we had to leave our condo and the rental car had to be returned we had to go to the airport. Even though we had a business class boarding pass to Washington, since we did not have business class to Montreal we could not access the lounge without paying a $59 fee each. This does not make sense to us. Since we could not meet our original connection United booked us to Montreal via New York LaGuardia on Air Canada. In Washington a further delay got us into LaGuardia too late to make our connection to Montreal so we were booked on another Air Canada flight 3 hours later. We were originally scheduled to arrive in Montreal at 10:40 and arrived at 19:55. A totally exhausting day, United did not offer a meal voucher or any type of compensation. Air Canada did give us a digital meal voucher. The food in United business class is poor among all meals offered. The pods look nice but are not that confortable. Overall would not fly on United again.

Plenty of room for me and the cat in Premium Economy. Seat was comfortable. Boarding was a breeze. The lady at the special check-in desk was great, super helpful and professional.

For the most part united was a good experience, how ever when they came by with the snacks and water, they completely passed by my wife and I. As we were in separate rows. On a 5 hr flight we were not offered water

Fantastic crew. Flight was delayed at last minute but we were given updates every 20 minutes and the crew was so friendly and considerate. I miss the touch screens on the back of the seats, wish they would bring that back though.

Our seats were all the way in back of the plane,

Food choices were very limited. Taste of the dishes was average.

Maybe add a seat trade app for flyers that didn’t get seats together

The flights were terribly delayed and then cancelled which forced us booking another night at the hotel. Very poor management from American Airlines

Crew was late. Baggage was late. 2hs inside the plane waiting fro de-icing and traffic. A 3:30hs flight ended up being almost 6hs inside the airplane.

Checking in at the counter was very disappointing. The lady had a very bad attitude and smart at me. She had no smile, did not greet me by name, or acknowledge me as a valued customer. Poor reflection of the airline.

Miami lounges were overcrowded and we were unable to get in. We only had a short time. But the banks are too tight in all American hubs

I was pleasantly surprised with an upgrade at boarding. I finally had a mostly gluten free food options and a very attentive attendant.

Very poor. Our special services attendant gave us incorrect information. I also was mishandled at landing. There was no wheelchair waiting. I fell deboarding the plane. Appalling!

Boarded over an hour late, no communication, the sign just changed, no attendant to answer questions - she disappeared forever (hiding). Small plane and couldn’t hear the overhead nor understand.

Paid for a window and was assigned to a middle seat with 2 very large people on each side of me. Flight was sold out and I feel I need to be refunded foe paying for a window seat and being put in a middle one..

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.

The senior flight attendant was engaging, funny and made everyone feel at ease. She is an asset to your team.

Needs legroom for tall people. Needs to offer a glass of water.

They changed our departure time 6 times before I even reached the airport. Delayed, Ontime, Delayed Back on time, Then Delayed. We finally boarded the plane and then we had to sit on the runway for over an hour only to be told they were taking us back to the gate for an additional 2 hour delay. Lack of communication and a complete waste of time! Never again!

I was traveling with my son and it was our first time with spirit so I didn’t realize our seats weren’t assigned. They scrambled and gave us seats next to each other. Also My son got sick on the plane and they really took care of him. Super family friendly crew and experience!

Great. I didn't eat or drink anything, nor did I have an option to be entertained, so i answered "okay"... but those categoriesreally don't apply. Everything else was great.

More groups for smother boarding, I didnt have any food. and there was no entertainment

Not bad but I was told that I got a 1 carry. When I got to the gate I was told my purse was considered my carry on. I had never been told that before.

The flights were on time, the schedule was convenient for me, without delays.

Bare bones but a complimentary class of water doesn't seem like too much to ask.

You get what you pay for with this airline. If you want comfort be ready to pay, the regular seats are like hard plastic bus seats and they don't recline, so again you get what you pay for, a cheap flight that is just alright. Which is what I wanted.

Check in at Philadelphia international was absolutely terrible! I fly 2 to 3 times a month and avoid frontier at all cost and will never fly Frontier again! The night before travel, I tried checking in however, the app was giving me an error, so I went to the desktop, which instructed you that you need to use the app. The next day I presented at the check-in gate after trying at least a half dozen times prior to getting into the airport and continuing to getting the error in the app. I actually had rebooted my phone numerous times and reinstall the app just in case. My phone is only one generation older than the current model. It has no problems completing a frontier flight purchase or any other app issues. There was only three frontier employees working at check-in and a huge line while I was in line I continued to try and check in via the app. As I approach the desk, I was dreading dealing with the agent. He was extremely unprofessional, anti-semantic & very ignorant, and mean to the people in front of me, as well as the people who ended up being behind me. He literally told people “Man I don’t care bout y’all” in his native dialect! Maintaining my composure I approached and explained the situation. To which he replied, you’re gonna have to pay then! I don’t understand. It’s an issue with their app not allowing me to check in! Not my issue! He told me if I pay cash it would be $15, $25 if I pay credit card. I don’t understand a $10 difference for paying with a credit card? I am completely cashless so I continued to try using the app to avoid the $25 fee, Which I still don’t believe that I should be responsible for since it was Frontier’s technical issue!!! I continued to check in via the app a couple more times after he verified I was doing everything right he proceeded to continue to belittle the people behind me. Yelling at them saying I don’t care about you people! I cannot believe that this is the way that businesses would treat its customers! Unfortunately, the black mail with dreadlocks did not have a name tag all he had was a frontier sweater on! For the $25 fee that I ended up getting charged on my credit card. I should’ve just booked originally with Spirit or any other carrier! I have no problem paying fees that I should be responsible for, but when it’s due to a technical failure of a company, the customer should not be responsible for it! I cannot believe that it’s not frontier going out of business!

they delayed my flight which ended up, causing my layover flight to leave without me, resulting in me missing a flight and having to stay overnight in Houston international. I got no compensation other than a flight to my original location only a day later. i’ve never experienced such a unprofessional situation

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.
