I would not have changed anything… It was a perfect fight

Pros: "Crew very attentive but not intrusive. Food very good."
Cons: "I did not find much to watch on entertainment system. Have to get crew to assemble flat bed, a bit of a nuisance. Also to turn it back into a chair."
Pros: "Wonderful trip, Super nice Crew , perfect meal , great entertainment system"
Cons: "Can not be topped up"
Pros: "Crew was okay"
Cons: "Did not get the food I chose. Seats were not clean and clumsy"
Cons: "For business class SQ, the crew service was severely sub-par. Seat arrangement same as in bigger 777, so actual space is much shorter and therefore uncomfortable for sleeping and lounging."
Cons: "For better leg room in business class go for the bulkhead seats"
Pros: "Hotel location is convenient, quite comfortable and clean."
Cons: "I love the foods in Hongkong, so many varieties . Price wise is affordable."
Pros: "Prompt boarding, friendly service, decent food, plentiful entertainment. Singapore Airlines was a great choice for my flight from Texas to England."
Pros: "Everything about this flight was top notch. The inflight entertainment, touch screen and remote controlled, was so good i was up the entire time watching movies Black Panther, Downsizing, DeathWish, Pacific Rim and listening to the wonderful library of music, i was surprised at the range of music, from uncensored rap to big band."
Cons: "Nothing"
Cons: "We were not provided vegetarian food on two legs of journey although we had earlier informed the airlines."
Pros: "Fast and easy to board nice crew worked fast and smooth large proposal for entertainment"
Cons: "more diversity of beverage offered Also please propose coffee or tea before/after dinner and breakfast, nobody proposed me and I thought it would come later but nothing came. I should have asked before the end of the service but I was surprised it wasn't coming automatically."
Pros: "Everything and everyone are Good and Nice ."
Cons: "For a long flight ( 16 hours or more ) , if someday I can afford First Class , that’s make my life . Thanks"
Pros: "Cathay Pacific always has courteous and caring crew. From the pilot to the attendants everyone enjoys their jobs and it shows in the amount of care and effort they put into ensuring that everyone has an exceptional flight."
Pros: "Food choices were great"
Cons: "flight was super bumpy but not the pilot's fault"
Pros: "Reasonable leg room in the economy"
Cons: "Flight was delayed for 2 hours I could not take on board by carry on luggage because it weighted 10kg. Food service was poor and not well organized"
Pros: "Though a long flight.. love flying with Cathay!! The crew was fabulous!"
Pros: "Somewhat disorganized bec. People lined up even if swat numbers have not been called."
Cons: "People trying to push their way in the line. Color coding of tockets associated with colored line coding may improve situation."
Pros: "their korean movies"
Cons: "they have worst coordination between airline crew and airport personnel who is in charge with services taking care for the handicap they forgot to board my aunt so i had to help my aunt board then the crew informed me i am not allowed to bring her in the plane and leave the wheelchair in the tube i had to bring her in the plane since my aunt was anxious other people in wheelchair was already brought in and she was left behind"
Cons: "Plane was old and not Super comfortable. Also no WiFi!"
Pros: "Super friendly inflight staff, especially on my flight to canada"
Cons: "Nothing"
Pros: "Friendly crew"
Cons: "Too much noise in the cabin. Ear protection should be recommended by airline."
Pros: "They are very organized small air line . Our flight was on time"
Pros: "***Our luggage did arrive as promised. ***Our flight from Tortola was cancelled, almost ensuring we would miss our connecting flight from St Martin. Thankfully some employees at the airport (Don't know to what airline they belonged, I don't recall seeing a single WinAir employee the entire time) hired a charter TurboProp for all of us (about 15 people). I think the kudos go to the airport rather than WinAir."
Cons: "*** If you are travelling to the BVI's and travel on WinAir, be aware that if your checked luggage weighs the limit that it will most likely come the next day. This happened to my girlfriend and I on separate occasions. While we did both receive our luggage the next day, there was no communication from WinAir. I had to call them repeatedly and stress the urgency with getting the baggage (I was on a chartered boat. I didn't want to hold the boat up for my bag). My theory is that the luggage gets sent on a boat from St Martin to Tortola as heavy bags can't be brought onto the island hopper airplanes they use to shuttle between the islands. *** After waiting at the Tortola Airport in the departures area for about an hour (about 10 minutes before our plane was to take off) I hadn't seen a single WinAir employee. I finally asked an employee of another airline if they could tell us what was going on. About 15 minutes later someone (Airport rep??) came out and told us our flight was cancelled and that they had booked us a charter turboprop to ensure we get there on time. After about 3 minutes we were ushered out to a plane that was loaded with our luggage and ready to go."
Pros: "I love flying Winair between SXM and EUX. The flights are short, safe, and provide a beautiful view of the beautiful islands."
Pros: "There is a magnificent view of the island on the way in. Make sure you have a camera ready!"
Cons: "The flight was delayed 2 hrs. They don't offer connecting the bags with other airlines. I wish it could be a better option"
Cons: "Terrible flight, over an hour late and no one knew how late was the flight...will never fly again with this company, will use Air St Barth..."
Cons: "Flight was delayed up to 45 minutes due to lack of grounds staff to load luggage on plane"
Pros: "Quick, smooth flight (a bit of turbulence). Great pilots and counter personnel were friendly"
Cons: "Left late, no update to passengers to say it was delayed."
Pros: "After booking through kayak, they lost my reservation and I was put on standby. I was treated very rudely at check in and I almost missed the flight."

Delay flight more than 8hours waiting and poor customer service!

Plane was extremely small so mind the size of your carry on

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: "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"
Pros: "Crew was good. Got there safely!"
Cons: "Maintenance issue caused us to have to get back off the plane, causing delay. Better safe than sorry, though!"
Pros: "The crew member was memorable in a great way. Enjoyed his job and it showed."
Cons: "Arrived admittedly later than i normally would due to ferry issues but it should’ve been plenty of time to board the flight. No one was at the check in area and 20 min later when we located someone from intercaribbean we were told it was now too late but we could get a refund but later refused"

We were delayed, but there was never any update given. Everyone was standing at the gate as boarding was supposed to commence at 13:10 for a 13:55 flight. We didn't actually start getting on the shuttles to the plane, until after 14:00. No updates, no information given at all.

Scoot refused to change my flight even though I had booked a flexible ticket. MyTrip wanted to charge me an extra $271 for a ticket that was only listed as $217. I complained about this to scoot and they didn't give a shite. So never again will you be getting money from me Scoot. You can Scoot off.

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.

Extra luggage after you purchase 1 is gonna jacked u up to 800sgd which is so up to the hook... you could buy 3 round trips ticket on that price.. im so disappointed.. im not gonna choose this airline anymore.. horrible experience...

Instead of the flight attendants talking to each other they should have been monitoring the passengers. The person beside me took a phone call literally 30 seconds before the plane landed. As we were going down the runway ( from landing ) a person in the row in front of me and behind me made phone calls; CRAZY

Pros: "Nothing. We had to sit on the runway for an 1 hour 40 mins. Staff didn’t even give away water, you had to purchase it... outrageous"
Pros: "GREAT CREW AS ALWAYS THE SEAT WAS COMFORTABLE AS ALWAYS."
Cons: "FOOD WAS ORDINARY NOT WHAT I ORDERED, MY NEIGHBOR IN THE CHAIR OPPOSITE HAD WHAT I WANTED AND IT LOOKED DELICIOUS"
Pros: "Not sure if I have much trust in the crew. Most of the female crew would walk past passengers who had their seats reclined or in the toilets and other situations and wouldn’t notice (during take off and landing) and the guy would come past later and do her job for them. Ground staff in Bangkok"
Pros: "Loved the tinted windows on the Dreamliner! And the rainbow lights at the end of the flight. Scoot personal were excellant!"
Cons: "Things to know: Need to download an app before getting on the flight to get ScootTV. Plane was a little loud."
