Pros: "Singapore Airlines has everything worked out for you before you land. That's a great help. The stewardesses were just phenomenal and endlessly polite. I will definitely use them again."
Cons: "As much as I normally nitpick something, I literally have no criticism at all of Singapore Airlines. Everything they did was a step above everyone else."
Pros: "New aircraft"
Cons: "The willingness to provide a better quality service by the entire cabin crew and improved food quality."
Pros: "The boarding process was easy and straightforward, the seats were comfortable and had individual entertainment screens, the crew was very polite and helpful. For meals, everyone was given a printed menu at the start of the flight so that meal options could be easily made."
Cons: "My only complaint is that I would have liked to see more frequent offers for water refills during the flight, since water cups are so small and staying well hydrated on flights is difficult but essential."
Pros: "Average flight"
Cons: "Seats on this aircraft have very upright seats. Not very comfy"
Pros: "I didn't like the trip much. After the trip we found out that our body was bitten by fleas. Our body is now full of rashes, every part of my body is so itchy. We was seated in 61A and 61C, seems like in the previous flight a dog was sitting there or some kind of animal that left fleas in the sit."
Cons: "Please clean better the seats. This is unacceptable, not a good way to start a trip in Japan. We only hope to get better sitting in our last flight with SQ, from Japan to LA."
Pros: "everything..Singapore airlines is a amazing airline !!! there is a reason why they are no 1 for so many years..."
Pros: "The crew was great as usual. The food was good"
Cons: "Better seats - really uncomfortable with a packed plane and wailing infants even when seated quite a few rows away."
Cons: "The layover in Singapore was a nightmare with insufficient hotel accommodation, nothing but Asian food and overly officious security staff."
Pros: "Extra leg room, great service and good food."
Cons: "The entertainment system feels dated (no touch screen) manual rewinding of movies, selection of movies"
Pros: "Prompt boarding, friendly service, decent food, plentiful entertainment. Singapore Airlines was a great choice for my flight from Texas to England."
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: "The crew was friendly n the food tastes surprisingly good, though the portion was small. The entertainment was good. and temperature inside the cabin was just right. Boating time was quick."
Cons: "Actually I was disturbed that CX offers a tabloid newspaper like Apple daily, especially at this sensitive stage when hk is going through such turmoil instigated and supported by Jimmy Lai’s group. It is offensive that such a biased newspaper is on offer, when there are other Chinese newspaper with a more neutral stand. Cathy has been viewed as a sympathiser of “yellow” rioters because of its involvement by management n crew. Now it just brings it more to the memory how CX might be what the leaked reports that many equipment has been compromised by CX crew onboard. Many of CX customers are from middle class, and it could be a big turn-off. It is unwise to patronise a tabloid newspaper when the owner has been named by China as the culprit of the recent troubles in hk. It’s like offering Al Jazeera news on united airlines entertainment........During the whole trip, I was captivated by these thoughts."
Pros: "The flight departed and arrived on time."
Cons: "The plane was not the same plane I booked travel on. They changed it, so if it’s the 777 then it is basically widebody short haul seating in business, with a lay flat price! The seats are old and don’t work well. This has been an issue on all the flights I’ve taken between Tokyo and HKG."
Pros: "I liked the comfort of my location and seat"
Cons: "No wifi on a over 14 hour flight is ridiculous in this day and age. They didn't have wifi on both my flights. I would think twice before flying an airline so far without wifi."
Pros: "Food and drink good and staff served any time when asked no payment needed for alcoholic drinks"
Cons: "Nothing"
Pros: "seats that i selected was change when we enter the boarding gate without informing us"
Pros: "very friendly staff"
Cons: "seats could be more comfortable for long flights, better food choice"
Pros: "Very delayed flight that resulted to missed my flight going to davao"
Pros: "Except for one time service everything else is good"
Cons: "Staff forgot what I have asked for boarding could have been done using zones."
Pros: "Staff was welcoming, everything was well organised, food was good. Journey was comforatable ."
Cons: "More choices foe veg meals"
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

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."
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."
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: "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"

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.

I paid an additional fee for specific seats because I was flying with my two children. I even checked in online and confirmed my seats, so at the airport did not think to double check my seats. The lady at the check in desk gave me different seats that were not together, nor did she say anything, even though she could see I was flying with children. Got to the plane and only realized what had happened then. Scoot refused to refund me that extra fee or take responsibility for what had happened.

Pros: "The crew was excellent, especially the stewardesses."
Cons: "Their wifi service is ridiculously expensive $32 and it doesn't work."
Cons: "arrived one hour before flight, all counter staff had disappeared. On-line check-in was not available as an option, could not get checked in and as a result missed my flight"
Pros: "The flight was smooth despite bouts of turbulence. The crew ensured everyone was strapped in and the pilot made a prior announcement before flight take-off. Most Pilots don’t."
Cons: "The check-in process took extremely Long as there were only two counters open. The boarding process was a joke. Despite the announcement to board by rows, there was no enforcement whatsoever and it was free for all."
Pros: "Crew were good."
Cons: "I paid for priority boarding but could not find the queue easily to check in as well as there was no priority boarding line up during boarding. My seat did not decline at all. I paid for a window seat but got a completely blank wall. Flights were late."
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: "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: "There is nothing to say this is a no frills airline and that is what you get. Departure was on time and arrival was also on time. Food on any airline isn’t good at least on airline i fly. The important thing is getting there safely and this airline company does that."
Pros: "Overall it was a good flight."
Cons: "No offer to book my seat assignment during the booking process. A kiosk check-in would be a nice addition."
