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.
BarbaraFlew with American Airlines-Feb 2024
Allow Lots of time ; big airport Long security lines

the flight itself was totally fine. The crew were great and very helpful. The flight was delayed, however, over an hour without a lot of information as to why.

the flight itself was totally fine. The crew were great and very helpful. The flight was delayed, however, over an hour without a lot of information as to why.

Had to walk back and forth between concourses to figure out which gate I was supposed to be at. The app and the flight board in the airport had different gates listed. Was told numerous times to check bags only to get on the plane and find that there was plenty of room for bags. The flight was over an hour late which had me landing after the last train departed. WiFi was unusable

Maybe different snack selection. To much sodium in them. I know refrigerators are not available but there has to be healthier items.

Wasn't expecting this, but, we actually ended up getting assigned to the first row of seats!!!!! The extra legroom came in handy

Flights delays were communicated timely and helpfully, but there was a significant delay without any real effort to make up for that. Also, the in-flight WiFi was very spotty. That said, this was my first time with Southwest and I was quite happy with the service and staff otherwise.

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.

Delta always provides stellar service. I am always impressed and will try my best to travel via Delta if I can afford it.

I think in the future I cannot fly anything less than Comfort plus. The seats vary depending on the plane. The people are extremely nice and funny. I try to only fly Delta if I can help it.

Great flight. Thank you for the upgrade to first class.

I usually like delta. However this is my second flight that the wifi does not work

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.

We sat on the tarmac in Denver for over 30 minutes because a plane was in our gate. The pilot kept saying it will just be 5 minutes or less. However, we sat for over 30 minutes. Experiences like this make customers not trust what the pilot is saying.

Loved the easy process to board and the experience overall was smooth

Service was slow Flight was very loud at back of plane

Fine except from Chicago to moline three different gate changes and flight times

The food could have been better and the entertainment could have better movies or streaming.

Fantastic experience once again flying with United! There was great communication from the cockpit and one of the flight attendants went out of her way to get my two little kids some special treats which elevated our travel experience coming home.

Flight attendants need to know their plane. Seated in first row yesterday. The seat had about a 1 inch recline that was not adjustable. I don't appreciate being awakened to raise a seat that can't go any further forward and such a small recline is either irrelevant or the plane needs to be repaired. Not the way to treat any customer and especially the ones who have paid that level of money for the seats.

Flights was great, service and transit support was outstanding - but the food was limited and of poor quality - only a snack on the first hour for 2 hours 1/2 leg. and a light breakfast on the second 4 hour leg.

typical but they have finally enhanced the wifi on some UA flights. Boy, its such a huge improvement

Return flight was perfect. All on time and no hiccups. However, going was another story. I don't blame United for the weather, but I am rather disappointed in its response to my getting stranded in my layover city for the night. United gave me a $20 food voucher. That's it. But besides this policy, the employees were incredibly helpful rerouting me to my final destination in Fort Lauderdale, FL. So overall, 8 out of 10. 10 out of 10 for flight comfort, inflight service and before flight service. 5 out of 10 for layover handling.

Im reviewing a flight that hasn’t even taken off because it’s been delayed for almost 5 hours. Amazing. Great time. No vouchers. Nothing. Thanks.

The old CRJ700's are rough, slightly larger regional jet would have been nice.

Seats were very tight for a 17 hour flight. Baby cried for 15 out of 17 hours.

Good flight, excellent personnel; poor comfort, small seats, big cost.

This trip on American was the WORST I have ever experienced. The plan was LATE taking off from Tucson due to mechanical issues. It caused me to arrive late in Dallas, so I tried to move flights so I would not miss my dinner meeting. First attempt, that flight was delayed, Second attempt, that flight was also delayed. Got back on original flight, the mechanical issue was NOT fixed, so we de-planed and had to find the new gate. Overall, was which was 4 hours delayed and missed the dinner meeting. Friday return, flight from Orlando was on time and landed early. Then the next flight was delayed due to crew coming in late, and them waiting on other passengers. After 90 minutes of delay, we boarded, and then were informed the Fist Officer could not fly due to time constraints. At 12:15 AM we were offered a hotel for a 4:20 boarding flight. Not happening. DFW was COLD and no place to sleep. Plane delayed again to 6:50, but was late taking off AGAIN. Finally landed in Tucson at around 8AM. Should be refunded 75% of the ticket costs due to negligence, nothing more.

Cabin was bone dry, no humidity whatsoever, and pretty warm; and beverage service didn't start for at least an hour. I had to go to the back for water and the FAs tried telling me it was always this way for all Miami flights, which is complete nonsense. Avoid the MAX8 like the plague.

Im sitting here waiting over an hour for my golf clubs

Flight was 2+ hours delayed and they “misplaced” all 3 of our checked-in bags.

Overall, really good experience, on time and the comfort was there. Wi-Fi was easy to connect

Flight was delayed 5 hours only to be cancelled at 1:30am. I did not get on the rescheduled flight because of worry it would be delayed (which it was). I needed to drive home. Horrible.

Flight delayed 9 hours. On tarmac for over an hour after arrival. Will never book with Frontier under any circumstances ever again.

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.
