We were the only ones on the plane to Culebra, and left 24 minutes early. Flight was beautiful to boot!

Cape Air was great. Kayak was very poor. No ticket to print or explanation that they transferred to another service.

It was good. It was convenient and frequent enough to be a very useful flight to reach more regional hubs. I felt comfortable enough to sleep. During the flight but loved seeing the countryside when I was awake.

It’s less complicated from Culebra to SJU airport. Next time I will prefer to leave from Isla Grande airport to Culebra !!

10 seat Cesna. Equal parts transportation and adventure. 20 minute hop at 10000 feet and 160 mph, sitting 10 feet from the pilot. Panoramic views of the island. Very simple boarding, very low stress. VQS airport tiny, undeveloped. Highly recommended flight, Cape Air doing a great job here.

We traveled in a small Cesna so there was no food or entertainment. The pilot was excellent enjoy being able to see the places we were flying above. It was an OK flight.

Very smooth flight and landing. Pilot delivered his safety instruction in such a monotone that it wasn’t easily understandable. Words were said but he didn't communicate to us. If he was communicating to someone he cared about, he would have used inflection and other nuances of speaking. Virtually all emphasis was removed so it was just blah blah blah (really fast, like the end of a Pharma commercial)

My pilot on Cape Air was AMAZING!!!! I hoping that next time I fly I have him as my pilot. He made me feel safe and secure in his skills.

I so appreciate this service into and out of Glendive. Always a good experience with crew and support team.

It was not what I had expected but it was a great way to see the landscape.

There was a screen but no earphones that could use the older input so I could listen to anything.

Jet blue just had great service overall! Only a little turbulence heading out of Austin, otherwise the jet stream helped the speed of the trip!

Boarding was quick and efficient. The flight crew were friendly. There were limited food options available on the flight. The pocket guide said there would be salad and sandwich sections available on flights over 3.5 hours. The only food available were snack boxes. And those were limited as well. My flight was over 5 hours. The entertainment system worked well. I had both extra legroom seats and regular coach seats. The seats were not very comfortable. The entertainment controls in the armrest made it difficult to rest my arm without changing the channel on my neighbors TV. Overall, my experience was mediocre.

Purchased through 3rd party vendor which made everything difficult. Unable to check in online. Unable to get flight updates easily, tsa precheck information didn’t carry through, longer time to check in in person. Entertainment looked good but had to purchase conventional headphones to view.

Boarding was fast, easy, and we landed early. The entertainment system was very buggy and kept resetting throughout the flight.

Flight emergency landed in Chicago due to “Odor” in back of plane . Had to buy ANOTHER TICKET to get to Boston cash out of my own pocket . Then they would notchange my return flight time without a 400. Charge!!!! Insulting.

I purchased ticket so our daughter ( a minor) can sit next to her mother. No help at gate after kayak insisted that this could be done. She ended sitting by herself

Flight was as expected. But it was delayed an hour. Also, my luggage got damaged. So that sucked especially since the damage made navigating the airport difficult. Walking to get ground transportation is sooo far away now and my checked bag was difficult to carry.

we were an hour delayed after boarding and given no reason. Headsets cost money. Also there were openrows with no one setting in them but we were told we were not allowed to swtich.

Crew was very friendly. Did not like being jammed in the back middle seat. Don’t understand why I can not select an aisle for free based on first come first serve. Also first time I’ve been on a flight which attempted land then circled Detroit airport multiple times.
