Flights from Florida Keys to California: the best tips from KAYAK users

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.

dropped my bags at Seattle Delta curbside. 1.5 hours before departure. one bag oversized made it. the other was left at curb and mishandled. poor communication from delta in sjc baggage claim. No internet on flight and food choices in business are horrible. You are forcing us to fly Alaska which is shockingly better than the Delta experience. that is a low bar.

attendents were rude and the boarding was disjointed and poor

There was an incredibly surly flight attendant that ruined the experience

After boarding the plane had to wait an hour at the for the copilot to show up before we could depart

The cabin and bathroom experience was poor as the cabin and bathroom were dirty and showed signs of an older plane that had not been updated for Customer’s, comfort and health. There was gum on my seat when I arrived and dirt spots around the fan and light controls. The flight was almost entirely full, so there was no way I could be moved from my seat. Th bathroom had the peeling paint.

Great crew. Comfortable seating. Nice overhead bin space. My app didn't allow me to check in for my flight to BOS. When I called Support, they didn't fix it, but just told me to check in at the airport. Seat back entertainment was great. Could be better if the audio could connect to Bluetooth.

I'm 6' 2" and even in economy plenty of leg room

Delta continues to set the benchmark for traveler-friendly service with minimal disruption and clear communication within the mainland US (coast to coast). I am consistently pleased to be a Delta customer, and this experience once again met my expectations. There was a brief delay departing from MIA due to a technical issue that required the aircraft to return to the gate. However, the situation was handled professionally and transparently. Fortunately, my planned layover allowed ample buffer time, so the adjustment caused no stress. Overall, another smooth and reassuring experience.

This had nothing to do with Delta… The flights were on time and flawless. The service was excellent. We purchased seats in (aisle/middle) comfort plus since this was a cross country flight. Unfortunately, the woman seated at the window was 300+ pounds and, as might be expected, covered up about a third of the middle seat also. there was absolutely nothing that Delta could have done about that… I just don’t know what the answer should be. If you purchase a seat, you should should be able to use the entire seat and not just the portion that someone else is not sitting/oozing in. Disappointing…there should be something that could be done….I'm just not sure what solution could be.

Worst service and meal in Delta First Class ever. I am really surprised as a loyal Delta flier. There was no welcoming or warmth from the crew toward us or our fellow travelers in the First Class cabin of the Airbus 321 Neo plane.

The plane was so old. I paid a ridiculous amount to fly business and there was no internet for six hours! This can't be happening in 2026 and especially in cross country flights where there are a high volume of business travelers.

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

Connection times always good online, but not in reality when first leg is delayed (2 out of 2 times this trip).

I purchased a Polaris ticket. The plane did not have the lie flat seats - I was not notified. I actually can not believe they traded a dif plane and did not notify me or refund monies

Delayed too much. 1.5 hrs in the airport and another 1 hr in the runway. Got too late in the night. There was no proper food available.

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.

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 flight was delayed a very short period of time but they did not hold my connecting flight to San Diego, also through United. So they closed the doors before we got off our plane. They would only have to help the door open for another five to ten minutes. So I missed a court deadline for a manditory mediation settlement conference for my client. I had to get an associate to be there in person and be on the phone with him relaying what he needs to do the entire time. The court was very upset with me and so was my client. United cannot be trusted.

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.

Boarding always seems a bit chaotic. Seat spacing could leave more for leg room.

Flight was fine, but I was annoyed to have to pay for luggage again. We had paid for our luggage on our first two connecting flights with SATA Azores Airlines, but had to pay for luggage again with JetBlue at JFK airport. For one trip we paid over $500 for two suitcases to travel from Azores to San Francisco.

Terrible. Quality has gone down significantly. Plane was delayed. No instructions from the staff. Will try to avoid in the future!

Thought the economy premium experience would match that of the Amsterdam to Boston flight. Aircraft was older: chair didn’t lean back. I had to buy a blanket, which on the flight over was complimentary. Flight crew seemed disinterested all around.

The plane was filthy and worn - the seat pockets were stuffed with tattered food and torn pamphlets. The cleaning crew that came on as we were deboarding were grabbing handfulls of trash and perfunctorily wiping down tables with dishrags. It's been a while since I flew Jetblue and it used to be a great experience. After this flight I will avoid flying Jetblue again if there is any alternative.

JFK is the worst airport and JetBlue is the worst airline

A more comfortable seat. Padding would be really helpful but I've read the airlines don't want customers to be satisfied with economy seats.

Everything was good except checking bags . I had paid for two bags but it didn’t show so we had to do it again while people waited and we were struggling to get to our flight

Flight delayed 4 times on a non-stop from BOS to SFO. Then when landed in SFO had to wait for 30 mins for a gate AT 3:30AM.

The security line at JFK was one of the longest I’ve ever experienced - probably 45 minutes. I don’t know if JetBlue has control over it, but it detracted from the overall experience. Entertainment had good options, but the volume control was a bit small to tap on and the screen had a fair amount of interference blips. Clearer picture would have been better.

My experience with Eva sir was good except the long walk in LA Lex, that was inconvenient for my age,

The flight was delayed and gate changed so that was not fun and the flight to Dallas from LAX was very delayed on Sunday. It was just not a great experience due to the delays both ways.

Nothing available at the assigned hotel as far as brush, toothbrush, etc after forced layover with bags that departed

Cabin staff were very disengaged, spoke with no eye contact, dismissive. Disappointing compared to my United experiences.

Flight attendants were pleasant and helpful. Pilot gave fair warning about turbulence.

Unfortunately the flight was delayed. On a positive note the status updates in the app/text message were good

Flight: Started on time. Comfortable flight. Arrived on time. Crew: Very cordial and helpful. Drinks and snack was served with a smile. Overall enjoyed the trip. Regards, Hari Doss Chanchala Doss

A first class seat should fit a fat person, and this doesn't. The trays in the armrest are less functional than an ordinary tray in the back of the seat.

The experience with American Airlines was good, although the Philippines Airlines flight was much better (better seats, better food, better entertainment options, overall better). Again, the MIA to LAX flight was fine, but nothing in comparison to the comfort and accommodations of the Philippines Airlines flight from LAX to MNL.

Plane felt so crowded and tightly packed. The chair itself was not comfortable.

2.5h delay due to unruly passenger in first class. Had to be removed from the flight. No food unless pre ordered. Didn't know we would need it because of delay.

It got me to my destination? However we were an hour delayed departing, and we never received any updates or notifications from staff. Poor communication and customer service.

My experience with Frontier was terrible. We were delayed for 2 hours. At one point during the wait at the gate I left to go get a sandwich - I was gone probably 15 minutes. In my absence, they decided to move our flight up, boarded and left. When I came back the two attendants were very rude and I unavoidably had to purchase another ticket on the next flight. During this whole time, the Frontier app did not update the departure time, so I was SOL.

Flight was delayed by about an hour, once we arrived at LAX we had to take a shuttle to the baggage claim - it was completely disorganized. The agents at the shuttles were rude and unable to provide any information. Frontier charges extra for everything from bags to drinks - at the end it ends up being more expensive than flying the better airlines

Tiny seats, no entertainment, no amenities, delays, they charge for carry on and their allowed personal item is smaller than in other airlines.

I really didn't like anything. Paid for my checked luggage online ($79) and then was told that I would have to paid another $79 for my carry on. Was not allowed to enter the terminal until 3 hours before my flight and when I finally was allowed to check my bag and enter, my flight was delayed 3 times. When I finally landed, we were all instructed to "run off the plane" as they had to do a quick turn around to Las Vegas. Me and several of my flying companions will never fly Frontier again.

Our flight was canceled. I will never use Kayak nor Frontier for travel again. The entire experience was a headache.

Terrible. The canceled my entire flight when I requested a refund for a trip frontier canceled trip one way.

i was unable to check in the flight. refund requested

I think Frontier was very good at communication. Their app worked very well. Loading was great and the flight was nice and easy.

Great for the price. No wifi or entertainment, but gate agents and crew were fantastic and we boarded quickly and left on time.
