Wouldn’t let us check our stroller and car seat at the gate

Pros: "Clean cabin and good service"
Cons: "Not every body is doing extra miles to make customer happy"
Pros: "Spacious Premium Economy seats with excellent flight attendants looking after general wellness of customers."
Cons: "In-Flight Wi-Fi has archaic plans… 30MB Chat App-only Plan for 2-Hours. It also usually has a pause button to halt and resume the internet session later, but there wasn’t one this time."
Pros: "The crew were excellent"
Cons: "Seats and leg room not as comfortable as older plane. The entertainment system was confusing to use ( again older model) hence not as user friendly."
Pros: "Arrived on time."
Cons: "Was a B Grade effort by the crew. They were there to get their pay check & no more....very disappointing."
Pros: "The crew was lackluster; unusual for Singapore Airlines. Tall individuals will not like the business class seats."
Pros: "Nothing."
Cons: "Everything. Singapore Airlines had a great reputation. Imagine my disappointment. It was a horrible flight. The crew was nice enough, but inattentive. The food, if such a term may be applied here, was inedible. Just vile. In flight entertainment was a complete joke. Boarding was awful, but it always is. Seats were extremely uncomfortable. This racket is the ultimate way to rip somebody off of $1000. Horrible."
Pros: "personel provided excellent service"
Cons: "food was ok. A faulty entertainment system did make our flight feel longer."
Pros: "The seats were comfortable and the staff was very attendant!"
Cons: "No complaints"

i booked vegetarian hindu meal for my flights from delhi to hong kong, and hong kong to los angeles. on first flight, they said that they do no have my meal information. thank fuilly some veg meals were still left and i could eat. However, on second flight they game me hindu non vegetarian meal, and I ate shrimp without knowing. pathetic.

Pros: "Very attentive, friendly and multi-lingual crew. Everything was on time. Food was very good. Excellent."
Pros: "Good leg room and nice recline for economy. Good and service very nice."
Cons: "Everything was well done and organized."
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: "One of the nicest crews I've had the pleasure of flying with"
Cons: "Nothing I could tell at the moment....."
Cons: "Worst international trip I have taken in my 51 years. Was so cramped in my seat i literally could not move or reach for my things under my seat. Never again taking Cathay Pacific."
Pros: "The crew were friendly and efficient The flight left and arrived on time The plane was clean"
Cons: "The self service check in and baggage drop at Brisbane was not effective, requiring a lot of staff intervention and help"
Cons: "The stopover in Hong Kong was longer than I would have liked."
Pros: "Flight was delayed and the crew were very understanding of the inconvenience and late hour of the new arrival time."
Cons: "Seat was very uncomfortable - struggled to sleep comfortably."
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: "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"
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."

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.

It would have been nice if I could have actually travelled to Perth. I injured my back and was unable to fly. Scoot refused to change my ticket saying it was not flexible. However I purchased the ticket through MyTrip and it was flexible. MyTrip wanted to charge me an extra $271 to change to a ticket that was only listed as $217. Never again will I fly Scoot or book through MyTrip

Me and my Partner were in seats 6A and 6B. (Which we paid a premium for). Unfortunately the person is seat 6C was large and because of his size my Partner was squashed to the point of discomfort and unable to sit properly. We requested to be moved to some empty seats and two hours into the flight the crew moved us. Perhaps it’s time airlines began checking passenger sizes to ensure they don’t encroach into fellow passengers seating space!

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."
Pros: "Head rest not comfortable. Short distance okay not long one."
Cons: "Plane is old i think. Take off and landing time plane some shaky and sound not pleasant."
Cons: "You can choose your seat but when you pay you can choose a seat and I don’t like this"
Pros: "Good price. Was on time, seats were comfortable, helpful staff"
Cons: "No use of headphones 30 minutes before take off and arrival"
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."
Cons: "Seats we given did not recline .as they were just in front of emergency exit . The extra leg room seats were empty, but would have to pay extra to sit on them"
