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"

Copa performed as expected for the amount of money I was willing to spend for the flight; it wasn’t exceptional but it was not bad in any way either. The crew was good; friendly and straightforward. The food was airplane food, so no expectations there and the entertainment was lacking but that was my fault for owning an IPhone with a charging port that’s not compatible with the rest of the world. I’d fly Copa again.

Left my bags in origin city on a business class ticket , spent about 2-3 days in the same clothes plus the flight .

the planes are not modern there are no phone chargers

As usual, the flight with normal legroom was not very comfortable, but the second flight was much better because we had paid for extra legroom. It was very nice to check our bags without an extra fee.

LOCKED MY BAG WITHOUT CONSENT. Had to have my zippers cut upon arrival in Costa Rica.

Pros: "The seats in economy were confortable. The best thing was Copa gave us seats in the second line and my family traveled together."
Cons: "Coffe service could better the experience"
Pros: "The crew was very interested on help and attentive with the passengers. But the seat wasn't comfortable. The design of the cushion is not the best to be seating"
Pros: "You were on time, that is the most important thing in a fly"
Cons: "You could improve your entertainment, you are not a cheap company"
Pros: "That there was seltzer"
Cons: "The management of preparing the flight and plane so that it was ready for the trip!!"
Pros: "Copa was convenient and easy. Very easy boarding process and I appreciated the day flight."
Cons: "This is a business class that is equivalent to a US carrier domestic first class. Good seats, not lay flat but wide on my 737-800. The food and service emulated say American Airlines Domestic 1C as well. Everything was just good enough, and much cheaper that international business on the majors."

Plane took off without me, my stepdad and a dozen other passengers. It went from an hour delay to boarding in 15 montures without notifying anyone. Names were not called overhead. Now I’m missing a day of work and stuck in Charolette overnight paying for a hotel and Ubers out of pocket

I arrived to the airport 2 hours before my American Airlines flight was scheduled to take off. I have TSA pre-check. The airport was crazy packed when I arrived. After momentarily standing in the pre-check line, the TSA agent said that I am not pre-check. Of course I said that I am because I entered my KTN number on all my traveling sites and programs. I had to get out of line and go back to the AA counter to discover that American Airlines did not add my KTN to my boarding pass. I had to call TSA to find out my number, then have AA enter it onto my boarding pass. The emblem would not load onto my boarding pass. By this time, I decided to use my Clear in order to get through TSA but the line was ridiculous long. By the time I made through TSA, I missed my 11:08am flight and was re-booked for the 5:30pm. This is after the AA employee told me I should have gotten to the airport early. AA use to be a dependable airline not I use them only if I have too.

Average - flew with Jet Blue internal and it was far more comfortable and better food and entertainment. Notable difference

Flight from SBP to DFW 1. They rerouted us through PHX 2. Delayed flight out of SBP for 3 hrs so we missed our connection Downgrade on rerouted flight. Back of the plane, center seats, didn't sit together 4. Return flight out of DFW same exact thing. Delayed, missed connection, Downgrade + they lost our luggage! A complete mess.

On the new 319 NEO? seatback entertainment system did not work even when the flight attendant rebooted it. At least I had my cell phone to connect with wifi.

Good flights. Departure and arrivals were on time. DFW was a little problematic in that the Skytrain without prior notice bypassed the Echo terminal so that delayed my arrival at my connecting flight.

Do not eat the bagel! Otherwise, good albeit late, breakfast in first. Boarding downgrade only because flight was delayed due to plane change due to undisclosed problem with original aircraft. I did not use entertainment.

Because I can’t stand very long in one place, I was allowed to reword.

It was a good flight. Of course it was full, but it went well.

Overall the flights pretty good. The snacks we’re good and they were plenty of them. Both boarding and deplaning went quickly.

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"

If you take this airline, they WILL change the flight time, and make you miss your connection. It has happened every time I used it. It's so unreliable that I think it shouldn't be offered on Kayak. You will regret it!

In addition to the fact that Silver changed the flight time several days before the trip without offering any choices , I was sick with Covid and unable to go on the trip. I tried to ask Silver for a credit for a flight when I’d recooperated but they don’t do credits, even for illness. I will Never fly on Silver again

I canceled due to a 7 hour delay. Was forced to book another airline last minute , very expensive. Silver Aorways sucks

I spent hours with orbitz to get my tsa # on my ticket. They didn’t have a place to enter. I will never use orbitz again. No customer service. A number in which u press offered options and the message replays instead of getting customer to that area. Silver did not make the promised call back. Finally someone responded to my email and took care of it after I lost hours of my vacation arranging this. Staff on flight barked orders.

Our pilot and flight attendant, Desiree, were great. I always fly this route and this crew was better than most.

The worst flight ever; 1st and last flying to this airlines

Easy boarding and deplaning. Short flight. Water was given but that was it.

Flight was delayed a bit since booking but otherwise everything was very good.

While this is a VERY SMALL plane; take-off to landing was fine. It's the constant departure time changes that wore me out and I'll try to never use this inconsistent airway again. Four delays in one day. Done!!!!!!

This has been, by far, my worst experience with an airline company. I had a reservation for a Tuesday at 8:30 pm departure from Gainesville, FL (1.5 hours - direct flight) I received an email on Monday that my flight had been changed to Monday at night to depart from Jacksonville, FL (and it was an 11 .5 hours flight ). There was no way I would have had the time to gather my things, drive 1.5 hours to the Jacksonville airport, and make it on time to board the plane. Besides, I had a full day of work on Tuesday. The only good thing I xan say about Silver airlines is that they did give me a refund, but I had to wait about 4 hours for a call back
