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 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.

Pros: "ground crew, pilot, flight was smooth and gate connections to Jet Blue in Boston were fantastic!"
Cons: "leg room"
