Airline reviews

I had the worst experience of my life in travel. Due to circumstances beyond my control (catastrophic traffic accidents on the highway between Gold Coast and Brisbane) I missed my flight for the first time ever. Because I booked through Kayak Singapore Airlines were not interested in helping me. They told me to contact the agent that I booked through. I was extremely stressed as I had connecting flights in Europe. First Kayak told me that the next available flights were in four days time. Then they told me that they could do it but at a cost of $2600 AUD. When I agreed he told me that he was having trouble getting it through Singapore’s system and he would contact me further once it had been done. When I had not heard from him after several hours, I phoned Kayak again, spoke to a different person who said he could do it for $8200. I declined and told him to cancel the booking. The worst part of this experience was that I had booked 5 flights altogether with Singapore including Premium Economy on two legs and Singapore cancelled all my flights including the return legs leaving me with having to completely reschedule my entire trip. Kayak refunded me $2000 from $5200, obviously leaving me out of pocket. This has left me feeling that I will never deal with Kayak or Singapore Airlines again.

Crew were so busy Anna so awesome. I was in a seat that got my food nearly last but the crew were Just awesome.

No frills airline with minimal leg room and no entertainment

Lounge a access was excellent as was the attentiveness and service from the crew as always. The food and drink supplied were of good quality. The entertainment system had a good selection and I liked the mapping system supplied. However the screen wild have been bigger and the operation a little smoother to navigate. The seats were barely comfortable, but adequate.

Headwind delayed our flight which wasn’t the airlines fault

Horrendous. We upgraded and they took the money but cancelled one of our tickets. The recline action didn’t work on the seats for the flight from Singapore to London, pre booked meals but they seemed to have disappeared as well.. Phone customer service was horrendous. Took 5 phone calls and no fix. Craig at the airport was the only one who seemed to be able to get the ticket back.

Food could have been better. Too many passengers getting up and down all the time.

Delayed 1hour due to storm still didn't get window seat for third flight despite paying £240 extra to book them

It was an average flight. I would have expected more from this airline. Food, seats, service, etc was just average. I just give them some extra points for offering free WiFi on board with just a Krisflyer account.

Airport lounge for business class is too crowded and not comfortable. Poor foods and facilities. Boarding was delayed. A lot of coughing people in the flight even in the business class, which indicated poor screening and health risks.

There was no screens on the flight, and no wifi with which we could connect to the internet and stream any content. This was a smaller plan so the business class seats were a bit tight. No hot towels or welcome drinks like when you fly on the bigger TG on the same route. The food was excellent, much better than the previous Thai airways business class meals. It was also nice that they offered eye masks for easy sleeping.

Excellent airline. The plane was clean and the staff were very attentive

I'm not interested in improving the airline. Therefore, I won't explain this in more detail. Next time I'll try a different one.

The flight (boarding) was delayed by 40-50 minutes and there was very crowed. They need to improve on the timeliness & boarding process. (They asked passenger to board in groups, but the 2nd group was standing there waiting for 20 minutes!). However, services from the crew was very good, also the food was good as well. I also found the legroom was quite comfortable.

Except that our flight was cancelled, by mail, and later moved to 12 hours prior, then the experience was good. In Bangkok we were offered a hotel, it was fine, but would have been nice to know in advance😉

Although booked meal of fruit only The crew had not received this special meal The same happened on my flight Bangkok / CAN The films are so old that best is to use own computer to watch downloads . Serve nuts but they do not warm up . Service is attentive , WC clean

Delayed flight in Singapore caused the transfer at Bangkok to be very stressful. Fortunately, no elderly were in this trip, else it will not be possible to catch the connecting flight. There were also several occasions throughout the flight journey where some of the passengers were not wearing their seat belts despite several remainders from the stewardess.

USB charging port was not working at my seat 48K.

Always liked Thai Airways but in the past they have been very expensive, not being a millionaire just yet, I will use cheaper airlines. Bangkok to London £370 11 hours 45 mins. Old plane but ok. Lovely ladies on board, very polite. Food was ok. Will always use them if the price is right.

Could have been better. I prefer Thai airlines only but it hasnt been reliable.

Food no choice just give it seams trying to finish what ever you have in hand

Overall experience is good but if the food menu can change to authentic Malaysia food will be good. I.e. Nasi Lemak, Char Kueh Tiew and etc

OK seats comfortable, easy boarding/embarking, excellent connection to domestic Malaysia flight with baggage checked through without customs. Catering especially drinks borderline ok luckily less important aspect

AC not working, just slowly blowing room temperature air. Long taxi time does not help as well. Sweating all over the whole trip.

Did not take as cancelled 3 time so took another airline

The IFE is quite unconvenient if using our own device. Not all passenger brought their own earphone/headphone.

chaos boarding. Crew in business class seemed short staffed and lacking in attention to details initially, but did improve during flight.

No recognition for one World Emerald member. Business class seat has flat bed

I had purchased extra leg room for all legs of the flight but due to a delay in leaving Perth I was put on another flight but with Emirates. My luggage was initially lost but later found and my suitcase was broken. I ended up losing my upgrades

The flight is awful, food isn’t very tasty or good, entertainment sucks

“They carefully called each boarding group in turn, only to herd everyone onto a bus for the drive across the airport apron. By the time we reached the aircraft, all semblance of orderly boarding had disappeared and it became a complete bun fight to get on board. Rather nonsensical really — why bother with boarding groups in the first place?”unless you are at an air bridge!!!

Crew, friendly On board services: terrible: no movies, no screen, no entertainment over wifi, no free water. Totsl Entrapment

3 hours delay ,we changed plane after boarding and waiting inside

Boarding took forever. It's also weird that we paid more (for preferred seats) to get on the plane last. Inflight WiFi never worked the entire trip. I want my money back.

WiFi didn’t work on both sectors so made killing time harder - planes clean modern and good flight crew - would do again if WiFi works

We had 2 attempts to land at Singapore Changing during a thunderstorm. Everything was delayed by 1 hour plus.

Was on scoot plus. The only good thing about the flight was the spacious seats. Tables and armrests were extremely dirty Food: bad Entertainment: non existent Wifi: unable to connect, then was painfully slow that we couldn’t even send messages Good thing we had a night flight, so we just slept throughout.

no charging point. food offering is limited and very much on the budget line. Overall is not satisfying for such a price and duration of flight.

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!

A good standard flight, a little delayed, on the return flight, comfortable during cruise hour. The food was tasty, the tea pleasant, standing in the rain, on Launceston tarmac, was stupidity. Just delay the exit from the airplane, don’t have us standing around, while another plane slows its propellers. That’s common sense, but overall comfortable, clean toilet, good legroom, I paid for that, last on, first off, get a front row seat.

Smooth flight with great staff shame about the hard seats

Cabin crew were really good. Flying in to Perth from Adelaide on domestic flight. The arrival for wheel chair use however has no air bridge provided. Unloading meant a scissor lift. Otherwise a good service.

Knees in back from passenger behind, limited seat pockets, no entertainment.

The Ryanair of Australia. Not impressed. Forced me to gate check my bag as it was over their weight limit. Charged me $125 for the privilege. Then said plane hold was locked and it would have to go out in the next flight, which was the following day. Explained that I was on a cruise the next day and the plane would not arrive until after the ship left, and that it would be impossible to catch up with the cruise at any point. Lady at the gate unimpressed. So to sum up they were ready to charge me $125 to lose a bag. Finally got it resolved by appealing to management, but the whole episode was not good for the blood pressure. The gate lady said they followed the Ryanair business model which means first time passengers get penalized for doing things that other airlines routinely allow.

Delayed 50 mins. Check in was excellent, boarding was good, everything else was OK and perfectly acceptable for a budget airline. Price was excellent. I noticed this airline had two other flights to our destination cancelled so not very reliable.

Horrible. The people that get this flights are very sick, dangerous and unhygienic

Jane at Sydney International airport check in was amazing. She set up the whole experience to be a positive one.

Not very good, no food and not drink ( caffe or tea). Never ever fly with jet star.

Worst flying experience of my life. FIVE HOURS delayed! Rude and unhelpful staff and poor communication from the grounds team. Never flying Jetstar again
