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.

Pros: "ground crew, pilot, flight was smooth and gate connections to Jet Blue in Boston were fantastic!"
Cons: "leg room"
Pros: "The pilot was kind and to the point."
Cons: "The guy who boarded us told me to wait as his computer could not check me in. 10min later he is rushing me to get on the runway. It was 30min before scheduled take off. I had ordered food and had to cancel my order before the café had finished, so he wasted food and did not get paid and I was hurried and boarded the plane hungry. I probably won't use Cape Air again unless it's an emergency situation"
Cons: "Boarded half hour late. No explanation. Pretty standard on Cape Air these days"

at the time for boarding the lady just call Group A and no other goups and everybody from A to F go inside without the right turn,and when we get in theres no more spsce for carry on , the ones that get in at not correct group from the back occupy our space !!!!! a mess !!!!

The boarding and flight were ok, but there were several painful issues. The flight was 3:20 in the air and almost four hours door to door, but they only had snack packs on the plane. They really need to have food on longer flights or make it clear to everyone that they won’t have food. They also advertise free WiFi, but it did not work for 90% of this flight. Again, almost four hours door to door. If I had known I was flying spirit for JetBlue prices then I would have planned differently.

I really liked the way snacks and drinks were available throughout the flight!!! The flight attendants were also all fantastic!

Best Thing flight took less time than programmed, quick entry and exit. Recommended!

Always like Jet Blue! It seems, however, that people are getting bigger & seats are getting smaller! We had a very full flight and I couldn't get an aisle seat like I always do. I wish there were more leg room. People sitting next to me were very nice though so it was fine to disturb them if I needed to use the restroom. Otherwise the flight was fine but a bit long.

I think the food / snack service was very poor. tehy could have done better. Evrything else was great

No wifi, not even while close to the continental US or Puerto Rico, no entertainment whatsoever (TVs not working). Totally disappointing.

For some reason, the seats on this flight seemed unusually uncomfortable. Speaking with friends who took another JetBlue flight later in the day, they brought up the same issue.

None of the in flight Direct TV worked. A better selection of Shows would have been better. The baggage was s low. Otherwise we enjoyed our flight!

The service was very good, will use the airline again.

Delay flight more than 8hours waiting and poor customer service!

Plane was extremely small so mind the size of your carry on

Other than lack of snacks, everything else went very well.

They don’t keep you updated on the flight status very well. It was late but nothing said

Pros: "Nothing!!! Horrible airline with horrible staff members."
Cons: "Everything. The staff and crew of Intercaribbean airlines are very unprofessional and not helpful at all. On top of the flight delays all the luggage for that particular flight was left in Kingston. Everybody was rather nonchalant and unapologetic about the situation. I was told I would get the the following day. The next day only two of my three bags showed up. I was not compensated for the inconvenience and was told point blank that they will only deliver one of my bags to my address even though they were the reason I had NONE of my luggage in the first place. They are disgusting!!! I would never recommend this airline to anyone."
Pros: "Nice people"
Cons: "A long walk to the D3 gate, but there were no amenities there I.e. snacks (to be fair a new terminal is under construction)"
Cons: "There was no air. I understand when you are on the ground it can be limited but even after getting to altitude there was no air conditioning."
Cons: "The flight was delayed for over three hours, apparently it is a regular occurence."
Pros: "almost nothing"
Cons: "The plane had a problem that forced us to turn around right after take off and as of this writing we still don’t know what’s going on or how long we are stuck here. Planes are old and apparently maintenance could be better."
Cons: "Was a bit difficult understanding the flight attendant, she had a thick Spanish accent"
