Flights from Florida Keys to the United States: the best tips from KAYAK users

Insights shared by verified travelers who flew the route from Florida Keys to the United States 
RobertFlew with American Airlines-Jul 2026
Get there early so you can enjoy some of at the great restaurants at the airport before you board.
IllaFlew with Frontier-Mar 2026
The TSA check lines are not all open 24 hours and you have to go thru a specific checkpoint depending on your Airline.
SoosnataFlew with Delta-Feb 2026
I prepaid my baggage fee through the Delta App during web check-in; however, I was unable to locate the receipt afterward. It would be helpful if prepaid baggage receipts were clearly linked within the trip details section and/or accessible under the traveler profile for easy retrieval. This added visibility would enhance transparency and provide greater convenience for customers managing their travel documentation. Overall, a small enhancement that could further elevate the digital experience.
JeffFlew with Delta-Dec 2025
Worth being a SkyMiles member for the free checked bag Plan extra time at Miami, the walk from the MIAMover to the check in was very far and the moving sidewalks were not functioning.
CindyFlew with American Airlines-Jan 2026
At Miami International, after check in at ticketing, be aware of the long walk to the American D Concourse. Signs are confusing, as there are several ways to go depending on your gate number. Stop and ask for clarification often.
CourtneyFlew with American Airlines-Feb 2026
Miami is a big airport with a lot of international flights, so give yourself enough time to get through TSA. Expect last minute gate change that is possibly 20 or more gates away from the initial gate provided.
Verified travelerFlew with Spirit Airlines-Jan 2026
Spirit Airlines counter at Key West is not busy/ long and security line is moderate.
DivyeshFlew with American Airlines-Feb 2026
Try to make sure you have 40 minutes of buffer with your connection.
JeffFlew with Delta-Dec 2025
Eat before boarding or bring your own snack on board.
ChristineFlew with Alaska Airlines-Nov 2025
Getting to the airport early is a must. Have a plan and map for your airline's checking desk. If you ask someone for directions, make sure they are clear or that you understand, a lot of TSA and airport personnel spoke English with hard dialects and some didn't know where the Alaska Air terminal was.
ReginaFlew with GOL-Jun 2025
It is a good connection, it gives you enough time to go through passport control and luggage claim and drop off. Eat close to the boarding gate because the next flight lasts 6 hours and there is no food service on the plane.
FrankFlew with Spirit Airlines-Jan 2025
Don’t get to the airport to early. The boarding is orderly so you don’t have to be there too soon
Verified travelerFlew with American Airlines-Jan 2025
Be ready to walk a long way through the terminal.
Verified travelerFlew with Frontier-Feb 2025
Do the check in always at the phone because they close the counter and the agents leave you without any solution
LatroyFlew with American Airlines-Nov 2024
Make sure you have plenty of time if you need wheelchair assistance
TadhgFlew with Silver Airways-Nov 2024
Leave loads of time for layover to your next flight
BamaFlew with American Airlines-Oct 2024
Also, don't be even a minute late checking in, they will deny you checking in or boarding and you will have to buy another flight.
Verified travelerFlew with Silver Airways-Jun 2024
Check the weather when planning a flight during the stormy season.
Verified travelerFlew with British Airways-Jun 2024
New York JFK is massive and the signage there for connecting flights is not so good as you need to travel via AirTrain between the different terminals and the signage for this is missing in some places, making it confusing as to which way to go.
Patricia LynnFlew with Delta-Feb 2024
Don't self check-in. You need paper tickets for flying from EYW.

Delayed and once landed waited very long for the luggage

Eveeyrime I fly they are begging for bags due to cabin overhead space. What they should so ia take the bags that are clearly too big to fit wheels first on their side. And those of us who give up the bag should really get their bags first. When boarding, nobody wants stupid jokes about how hot it is on board. Give us some cool air. Im usually sick from the heat by the time we take off.

Friendly crew kept coming by to make sure all was ok, provide additional refreshments, etc.

SW can't get their wifi right. I upgrade to insure wifi service but the last two trips had intermittent service. Not worth the extra costs.

Kayak could’ve posted the correct gate number. Almost missed my flight.

Slow boarding, limited food and drink portions. Bad delays and turbulence

The checking experience in Orlando was terrible, almost missed the flight. Too many travelers and Southwest completely understaffed.

Truly terrible. Will never willingly fly southwest again. Seats are worse than before they switched to assigned seating. One flight attendant was the opposite of helpful (rude, unhelpful, dismissive, and as my stranger seatmate said unprompted: a total prick). This caused me, 15 minutes into the flight, to book an alternate return flight home on a competing airline (first class 1.2k purchase instead of my existing planned flight) just so I would not have to ever be on that aircraft, with that terrible service person, with those horrific seats ever again.

Communication about the delayed flight was poor. We were told to move gates three times but that was bad information. We went from gate 128 to gate 126 and then to gate 123 and back to gate 126. Communication about the delay was bad. Ended up being 1 1/2 hour late getting home.

Southwest continues to do less for more money. Flight attendants used to be fun and friendly. But now it’s like they don’t even see you. Such a shame.

Both legs on the way were smaller planes, each had a mechanical issue causing a delay

Delayed flight. Dirty seats, dirty seat belts with food stuck on it from previous passengers maybe. No one cleaned the seats or flight.

No headphones, forced to sit in another seat that I did not book, had to check my carry on when I boarded the plane I saw backpacks and other non carry on items stuffed in the carry on holder! Horrible experience Wi-Fi did not work either

There was no food, so :( to that one. The flight was delayed by 3 hours. Not Delta's fault. Not the crew's fault. Considering how tired all us passengers were, everything went surprisingly well. The flight crew were very helpful, friendly, and professional. I always fly Delta.

Terrible. Waited on runway for 1+ hour after landing and then was brought to wrong terminal

Pushing back flight and ultimately cancelling it after multiple changes and hours of delays. Comm were terrible as to what was going on and what options were available.

Some of the passengers are coming on board with luggage so overstuffed and/or too large that have no business going into the overhead bins.

Boarding was quick and i made my connection early due to early arrival time

My flight was canceled, and instead of rebooking me on a non-stop first-class flight for the same day, which I originally had, Delta rebooked me on a one-stop flight for the following day. When I checked the Delta app, I noticed that there were available flights for both the same day and the next day. I believe this indicates poor management on their part.

My flight was delayed and I got back around 3.5 hours later than expected. I had to get a new connecting flight

This is related to my second leg of the flight, from Washington DC to SFO. I understand things happen, but I got home at 3 am for a 12:59 am landing. I live 10 min from the airport. Bridge breaks when a few rows of the plane are off? Maintenance didn’t catch that?

WiFi was slow as compared to trip down. Maybe because it was a night flight and more people were using it?

Excellent except for the 2 screaming kids who wouldn’t stop crying and screaming for the entire flight but what are you going to do? The flight was early- good experience

Kept changing the takeoff time and the moved it up so arrived when boarding had already started. Then sat waiting to taxi in for a long time

Leaving at 7 when scheduled to leave at 4:20 - you tell me. Understood there was a ground stop. Then having to "reboot" the plane because of a lighting strike, also understood. But basically the flight was a "clusterf#$%".

Wonderful flight! The crew was good, check-in was good and orderly and the flight was uneventful and good.

There was a piece of plastic baked into my buttermilk biscuit! I have a pictures. The flight attendants in first class were really apologetic, and tried to rectify the situation. I I am very appreciative that they were able to give me some packets of pretzels and gummy bears. I understand they don't personally handle the food until warming it up so I know it wasn't their fault. I don't know whether it was a newer aircraft, or different food packaging, but I was happy that when the food was being warmed up - it didn't smell like plastic. Jokes on me with finding plastic in my food.

Horrible experience. They delayed our flight 7 hours!! We had to seat at the airport with kids on 4th July all day!

Horrible I am at almost 2,000,000 miles on United. This was probably the worst flight ever. An hour and a half before takeoff I get a message that they’re changing the plane and I no longer have a seat in Polaris business Supposedly, there was a problem with the plane, but then there was no other plane Finally, they decided to bring a plane from Newark to Washington Dulles Of course the original flight was at 10:45 PM so by the time the plane got there it was 12:30 AM. It had not been cleaned. It had not been catered. They don’t really have people available to do those things when it’s not pre-programmed at 1 o’clock in the morning. The crew had to be changed And the new plane held 28 fewer people than the scheduled plane There is no way you can hate United Airlines enough The people at the gate were actually just fine, but it was management who was completely useless And did they send extra help to the people at the gate? Did they send supervisors? Of course not. Just don’t take United find somebody else or buy a boat

6 1/2 hours from Tampa to SFO on a Boeing 737. Cramped. No Service. No real food. One pass for coffee at the beginning and a second pass THREE hours later. And check-in in Tampa was nasty even by United standards. And I am at almost TWO million miles on United. It's a non-stop. But terrible service.

My flights were all delayed , mostly due to technical issues with AA aircrafts. I had to rebook my trip 4 times . I lost my whole day and finally arrived in LAX around midnight. This was a very bad experience with American airlines , I will always try to avoid flying with them

My flight was delayed close to 10 times over the course of the evening. I was originally scheduled to depart at 7:03 PM but did not leave until 12:33 AM, resulting in over 9 hours spent waiting at the airport. The only explanation provided was that the aircraft kept being swapped, with no clear reasoning as to why. Weather conditions at both DCA and Tampa were clear, so that was not a factor. The only accommodation offered was a $12 food voucher, which was entirely insufficient given the length of the delay. Overall, I was completely unsatisfied with this experience. A delay of this magnitude with no meaningful communication or accommodations is unacceptable, and I would have expected much more from American Airlines in terms of customer care.

if it's a mobile only entertainment experience, please provide a place to hold the device in the back of the seat.

Our flight was delayed to Louisville. What made this worse was they did not have another flight attendant to service the flight. This caused an even longer delay. Then when a flight attendant did show up, she chose to "swap" flights with another flight attendant. Therefore, we had to wait longer for the other flight attendant to come to our flight. This is information that the gate attendant should not have shared. Processes and execution at American are broken. Passengers are feeling it. Fixing this starts at the top of the organization.

Both the gate agent and flight crew did a horrible job of expediting the boarding process. It was simply miss managed. The airplane was late to Tampa. Therefore, they should have expedited the de-boarding process and also boarding process. This did not happen and caused me to miss my connection. I ended up with a 7 hour hour layover just to get home. The overall flying experience on American has simply been degraded. On-time performance is a real problem every single week. This has caused me to consider moving my loyalty to an airline that has better performance metrics.

Flight was on time. Boarding was smooth and orderly. Flight attendants were friendly and professional. Bags came out soon after arrival.

Luggage handling and communication is extremely poor. I landed in india 15th and recived luggage today. Based on my itag the luggage was in Germany. They kept me in dark. Etihad num er in india was non operatuonal. Had to call USA etihad. It should not be so difficullt. I came for 1 week business trip everything was screwed . This is the first and also will be last for me

It was ok because it’s a short flight. The attendants weren’t friendly and didn’t serve any beverages even through they announced that they would. Also. The attendants looked messy, not presentable

APU on the aircraft was not working. No AC while boarding. Plane was extremely hot and uncomfortable. Ground AC failed. Miserable experience. Arrival at DFW, no gate available. Not sure why that keeps happening at DFW.

Everything is poor, 1st of all American Air should fix the flight schedule, I never reach my destination ever on time,

When I was boarding my departure from Raleigh to Orlando I was inappropriately scolded by a female dog named Mia because I didn’t pay in advance for my carry on bag ($75). Frontiers website is confusing regarding pre-paying for carryons so it was a simple mistake. I also had paid for “upfront plus” meaning me and my son were seated in the front row with no one in the middle seat ($450 upgrade). When we were boarding Mia said “sir, you didn’t pay for your carryon” in a not so polite tone and told me to get out of line and come back to the counter to pay for my carryon. The way they had the retractable rope left me no room to circle back without making the people behind me move so I just stood there and then she said a second time “sir!! Go pay for your carryon” in an embarrassing tone. I then moved their rope so I could get back to the counter when a second female dog then asked “are you done!?!?” because I had said “do you want me to bulldoze the people behind me?” I then said you do realize I paid over $400 for upfront plus so I was certainly not trying to sneak a carryon bag without paying. Long story short, I am soooo done with discount airlines!!! By the time you pay for all the “extras” you might as well have paid for Delta Southwest or American! Frontier airlines sucks and I was embarrassed by a female dog named Mia!!!

Frontier feels like a family I Worked for Eastern Airlines back in the day and I felt the family vibe that I had then. Thank you

It was an early flight and most people napped/slept and the crew let us which was nice.

It didn’t happen. I booked it and then was told it wasn’t available and then forced to pay far higher prices for a worse option

This company socks. It's fraud. They canceled our flight yesterday, and today we were late because of a really long line at the check in bag. At the rebook station, there was ton of people. The workers were all rude. I am gonna make a report to FTC.

Flight got delayed for 5 hours no good explanation was offered ;(

There was no one at the counter to assist with our check in. The app didn’t work, so I arrived at the airport with time to check in and I couldn’t because no employees were there. When I finally got someone on the phone, it was inside the 60min rule and they said I could no longer check in and they could sell me another ticket. We had to scramble and pay an additional $800 for tickets and THEN AFTER (about 60 min from my original convo with customer service and 10min after original departure time) I had boarded my new flight, there was email saying my original flight from Frontier was delayed and leaving 2hr 50min later, but I STILL wouldn’t have been able to check in. Which means customer service should have been able to see it and let me check in because I was well within my check in time. When I call Frontier, they hang up on me. So their app didn’t work and they employees left and they take zero responsibility or assistance with their “customer service”

Everyone seemed to be in zone 1 for boarding. Maybe break it up a little. Otherwise, smooth flight.

The experience was good. No frills but I got there safe and sound and on time.

After boarding and un-boarding twice over 6+hours, the flight was canceled.
