Airline reviews
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: "Overall, the staff was amazing, so as the food and cleanliness"
Cons: "The space between the seats in economic seat"
Pros: "The crew was friendly"
Cons: "In this fairly new plane, the rows of seats are so close together, the leg room is minimal. When the tray is lowered, you feel completely squashed in the seat. The food trays are not picked up quickly after eating."
Pros: "I liked that on the longest leg of my trip - I had an entire row to myself to stretch out. Im old, things like that are important...along with compression socks...haha!"
Cons: "I think the food - I dont know exactly what, because we're on a plane - but I think it could be a bit more appealing? More greens, colors? Not sure, but it was okay."
Cons: "The person next to me had a distinct body odor."
Pros: "Flight was full but crew was attentive and very pleasant. Star Alliance Lounge at LAX had a good variety of food and drinks - Asian, western, small bites, snacks; red, white, bubbly and even a bartender who'll mix up cocktails. I love flying SQ."
Cons: "For a premium economy service, it was really good."
Pros: "crew were very friendly and helpful. flight was one of the best i’ve had"
Cons: "boarding at sydney was very confusing"
Pros: "Okay in general, nothing impressive"
Cons: "Food certainly need improvement, lacking in attention to ensure food quality. Crews need proper training in customer service."
Pros: "The crew werr very helpful and patient and so many languages they knew. Impressive they need a raise"
Cons: "The seats were uncomfortable I slept 30 min at a time on my 14hr flight. The food is nice but a bit bland the first time its amazing but after more than 2 planes mix it up plz"
Pros: "Great service and attentiveness with great food and entertainment, including a nice big comfortable seat!"
Cons: "Food was lacking, everything else excellent! Not enough components to the meals. Be nice to have cheese/crackers. Better salad."
Pros: "The departure and arrival times were good in order to sleep the night, and wake up in Tokyo refreshed. Cabin crew were fairly friendly, but not the Cathay of a few years ago."
Cons: "NONE of the business class center seats would recline. This meant in order to recline and get some rest, the crew had to dismantle your seat and release the locks manually. This meant the seat was in that position until time to land. So I had to make a choice to sleep or eat, horrible for CX."
Pros: "Attentive crew. Smooth flight."
Cons: "Entertainment options limited but that’s a very small complaint."
Pros: "Great crew, but I didn’t really like the Economy Premium seat. Eva Economy I thought was better."
Cons: "in-flight food and beverage choices needs lot of improvement"
Pros: "seat very comfortable"
Cons: "food and inflight entertaitment with very few choices are very poor - flight attendant always on the PA for meaningless message in 3 languages"
Pros: "Great crew and service"
Cons: "No good beer selections and the water had a bad taste l."
Pros: "Was good service onboard"
Cons: "They could be upgraded my whole itinerary and not just 1/4 of the trip"
Pros: "Loved the crew, very helpful and attentive."
Cons: "Food could be better. No goodies like toothbrush or paste or sleep mask, but this is minor. Website is really bad and hard to check-in online. They could really simplify the website and allow folks to add their favorite miles in there. just so complicated to do anything on the website."
Pros: "Cabot crew very nice an professional."
Cons: "I wanted an aisle seat but I got stuck with a middle seat."
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."
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"
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.
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!!
Pros: "The crew was excellent, especially the stewardesses."
Cons: "Their wifi service is ridiculously expensive $32 and it doesn't work."
Pros: "Air Crew was polite. Ground crew was the slowest and most inefficient group of people I've witnessed. There'd be 3 people working, but 2 of them would be talking to each other, letting the queues build up."
Cons: "Ground experience was pretty terrible at the airport. Most likely I'd avoid flying through here again."
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: "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: "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."
Cons: "Wasn’t allowed to board the plane because my passport only had five months left on it but you still let me book the flight and I was not refunded"
Cons: "You can choose your seat but when you pay you can choose a seat and I don’t like this"
Pros: "Crew were professional, friendly and efficient. Aircraft was clean in the cabin and in good serviced condition. Check in Staff were efficient, friendly and professional."
Cons: "Seating configuration in economy very small. My Husband is a tall, big man and was cramped by the seat pitch, which made his trip very uncomfortable. To think that we have to pay for such an essential item to life as WATER, when it is free on most other airlines....or at the very least you can get a glass of water. I couldn’t believe the charge price for a tiny bottle of water and the fact that you can’t even get a glass of water either. This is an outrage and a rip off to customers."
