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"

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."

Crew were attentive and friendly. Flight was smooth and early! I enjoyed the less crowded plane. Thank you!

We are gluten free, there were not any available complimentary gluten free options.

No meal on a cross country flight? SFO-MiA is pretty much the definition of a coast to coast flight. No meal provided. Sky high wi-fi rates too. Stop nickel and diming your customers.

The staff was unprofessional and didn’t communicate very well. The boarding process was very disheveled, potentially due to a power outage the previous day but there was no contingency plan to properly get passengers boarded the following day. Once boarded the aircraft stayed on the tarmac for over 45 minutes due to high winds. The communication was sporadic but an announcement was finally made an additional 30 minutes later that the flight was cancelled but we couldn’t get off the plane. Prior to deplaning one of the gate agents came on the plane and made an announcement for everyone to pickup their checked bags and take a card to rebook a new reservation because they didn’t have adequate staff. Flights were missed, passengers went to different airports and there was little to no assistance from AA.

You cancelled my flight by email then made it very difficult to get in contact with you. Then put me in a flight with a long layover in Mexico returning to the wrong airport in uk. Mind blowing my stressful. I missed see my grand dad because of you.

Apart from the delay due to unforeseen circumstances. The leg from sjc to dfw was fine. It was the leg from dfw to orf that we encountered issues mainly due to the flight attendant crew not being friendly. We had two small children and we needed some assistance to warm up milk so the baby would sleep. The crew just didn’t get it and made things very difficult. One made a remark that the baby’s dirty diaper smell was a “gift” to the plane in a rude way. Normally I’d brush that off as a funny comment if the rest of the trip the attendants were helpful or understanding of the difficulty we faced. But that wasn’t the case. We were met with rudeness on the second leg. Whereas on the first leg the crew were so nice and helpful.

This was not the BA business class it used to be. Mediocre food, attendants seemed stretched thin. All the little luxuries that used to make BA business fun were missing. Flight delayed and the explanation given was they forgot to pick up crew - I hope I misheard! Transfer in LHR “sticky” - we thought we had way too much time at 3hours but it was needed. Next time will try different route.

Flight From PHX to CVG was on time, very professional staff

The food at Admirals Club was really great Pijamas were a nice feature The flight attendant was very nice and great attitude The aa.com does not work well specially internet service Overall a very good flight .

Flight was delayed and missed connecting flight. Did not give warning about delay until we showed up at the airport. Not good.

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
