Well, I didn’t like much. The staff didn’t have any beverages except for coffee and water and they never came by. The food just sucked. There was no entertainment at all.

Well, I didn’t like much. The staff didn’t have any beverages except for coffee and water and they never came by. The food just sucked. There was no entertainment at all.

Pros: "The crew was excellent."
Cons: "The business seats at B777-300ER was very uncomfortable for a long distance trip with duration of 14,5 hours."
Pros: "Flexible seating due to only very few passengers. On time departure and arrival"
Cons: "In flight food service by cabin crew was spotty, sometimes they gave you coffee with dinner , sometime not, they are very forgetful. Please improve on this issue."
Pros: "The crew was amazing. It was my first time flying so I was a little nervous but they made me feel safe and welcomed. The friendly crew was honestly what made the whole experience great."
Pros: "Amazing crew and service. My kids were well looked after in business class even though my 2 year old was a little sick. Book the cook meal was excellent and great entertainment options. Seat was enormous!"
Cons: "Nothing significant!"
Cons: "The lunch part at the end was a little late we had just had a snack and a small sandwich so we didn't eat a lot. But food was great!"
Pros: "Good boarding, good arrival gate"
Cons: "Old plane, entertainment system is very old and screen bad"
Pros: "Crew was polite."
Cons: "For such a long journey, the plane could have been nicer."
Pros: "Amazing crew."
Cons: "Food focused on Japan on both legs, LAX to NRT and NRT to SIN. Variety would have been nice."
Pros: "Boarding was quick and easy. Blankets and pillows were ample and already at the seat."
Cons: "Food was worse than what I had come to expect from Cathay Pacific. Drinks were less frequent. Restroom facilities were not well kept over the course of the flight."
Pros: "Same thing they serve pork and no other substitute. The crew members are not so nice especially the one serving the food, some are rude to answer when I asked for something."
Cons: "Serve chicken or beef and not only pork for not all will eat pork.3 of us was not able to eat. Thats was not acceptable."
Pros: "The entertainment was good."
Cons: "Once the crew got the meals out of the way you didn't see them (at least in our section). You could go to the galley for water or a snack etc. Most airlines I've been on seem to bring drinks, etc to seats every once in a while."
Cons: "From the check in, to the food and cabin experience is worsened by far. Check in - no check in line for premium passengers.( really bad experience) Cabin crews could not separate passengers from other cabin consisting using lavatory there fore passengers constantly walk back and forward. (It’s really unpleasant) It’s. Not worth the money to paid for the experience and services."
Pros: "Crew was extremely friendly as expected from Cathay. The aircraft was substituted from the scheduled A350-800 to an A330 but it still had lie flat seats, just not as nice. The crew was very apologetic for the last minute schedule change."
Cons: "Nothing can be done about the aircraft swap, I’m happy they swapped with an aircraft with lie flat seats as I was exhausted and needed the rest before landing in HKG."
Pros: "The seat space, and the ability to recline the seat was surprising."
Cons: "It is what it is."
Pros: "Crew was helpful but 1 crew forgot my dinner drink which was a hot tea drink."
Cons: "Maybe write down who ordered drinks while serving dinner tray.. if there were turbulence the crew can go back to that list then setve it when seat belt sign is off."
Pros: "The crew was hard working, food was ok"
Cons: "Line up for boarding as well as storaging of our carry-on could have been managed better"
Cons: "Delays on both flights . Baggage in Dulles took well over 4o mins ... terrible"
Pros: "The seats were comfortable with enough leg room even in Economy class.The on-flight entertainment was excellent."
Cons: "I didn't like the food offered that much. Also, it seemed that the crew were not that good in coordinating among themselves and helping out passengers. There was not much option on drinks."

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"

Connection flights are smooth, both flight takeoff arrive on time, that will be the best u can expect. Food no order, service no complain, entertainment not seen, cleanliness can be improve.

It was a cheaper flight and it arrived early. I thought the crew were pretty noisy for an overnight flight, and my friend was not able to sleep because of the noise. Also I think it’s absurd they don’t provide complementary water. Why does everything have to be a surcharge? Airplanes are dehydrating and it would be beneficial to help passengers stay healthy.

U could offer everyone a drink ,juice or water.. coffe or tea ...ur air craft isn't a flea market ,where someone has to buy a tea or water!!

Cons: "Flight with Scoot are not very well organized. for as large a fleet and number of flight locally should be better. no onboard entertainment nor refreshments. Staff not very personable either."
Pros: "Friendly crew. Toilets kept clean. Nice ambience with the cabin lighting."
Cons: "My seat had a broken recliner button. Seat would recline but not stay reclined. If I sat up, seat would come up with me."
Pros: "The food was good. The service very good. Check in was so fast."
Cons: "Internet charge was very expensive and electrical outlet could not hold my charger. It kept falling out"
Cons: "You can choose your seat but when you pay you can choose a seat and I don’t like this"
Cons: "The flight cancelled.first we boarded twice and been waiting for 7 hours Inside and outside the plane thereafter they gave up and decided to cancel it ..it was nightmare"
Pros: "Overall okay. Food was not in our list because the flight is about one and a half hour. No entertainment as it was a short one and we departed earlier than the estimated time."
Pros: "Organised well. Clean plane. Excellnt comms from pilot and staff presented well."
Cons: "Could not recline chair"
