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

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"

The flight was VERY, VERY hot and the blowers weren't cooling it off...don't know what the problem was, but.....otherwise it was fine.

My flight from Avianca was 45 minutes late and it's very complicated to recheck in in ...also I have to say the silver desk folks were neither efficient nor helpful...so I missed my connecting flight. I actually got there before tge flight left but they refused to let me on....and gave me no vouchers for hotel etc

The cancelled our flight 3 times and we never made it to our destination. Every single airplane had a maintenance problem. Never fly this airline

9 hrs wait in airport then flt redirected to airport an hour away from our booked airport. Then at 8:00pm flight Cancelled. Silver supposed to book us on American the next day. Booked my husband but not me. Cost me Ubers, hotel, meals, new ticket and 1 hour taxi Cuz no flights to our home airport. Absolute disaster. Silver staff had no idea what was going on or what to do. Never Again Silver

Nothing about this flight was good. They are always cancelling or grossly delayed. We were delayed for 45 minutes for no apparent reason with no explanation or anything we could see and I missed my connection to Durham NC. I was on my way to my best friends memorial and funeral. Now I'll missed them both!!

Total disaster! The easiest flight was kept delayed till … cancelled! And before official announcement of the flight cancellation I was offered to join ongoing boarding to FLL so I had to change all my traveling plans, have lost my car reservation and a payed spot at the meeting I was going for to begin with! I had to no show to my flight back, because it was from different airport again!

The worst experience we had traveling. The worst experience we have had traveling. The service is lousy, I will NEVER choose this airline again.

Never in time always late, even on arrival gate not ready so waited on tarmac another 45 min

Flight canceled 11 hours after being delayed. Miss annual family vacation because of this

This was a short flight so food was not offered. The stewardess was great at giving water out. The baggage check at the airport was hideous. One person was untrained and had asked a question. The other two people were just dealing. Someone could have worked the line and said you must have a luggage tag and you must have confirmation. We waited for some people at the counter for 20 minutes because they couldn't find their reservation or they were missing their luggage tags. We were in line an hour and 20 minutes had to run to her gate just to find out our flight was delayed 40 minutes. The silver air website never updated with status changes on the phone. Horribly irresponsible flight company.

Did not get to travel, you canceled my flight and left me stranded for the hole day, it's another day and I can't get to my destination. I will not recommend any one to this away, bad service

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."

Friendly staff, easy, and on time. Needs improvement on booking directly. Also

No comments, the complete handling and flying was excellent,keep up the good works.
