AndreaFlew with Qantas Airways-Jul 2026
Taking the train is easy. If not allow at least 2 hours if it’s a morning flight. Also if you have to pay extra baggage. Ensure it’s paid before you go through immigration. Enjoy!
ScoutFlew with Jetstar-Mar 2026
There will be no internet or phone reception from the moment you start boarding. Send your goodbye messages before boarding. Wish they offered at least free wifi for messaging apps like WhatsApp. This seems to be common in Europe and great to include.
Goh Hua ShengFlew with Turkish Airlines-Feb 2026
early check in at the counter is available just that the downside would be arriving at an odd timing if stopping in singapore.
Verified travelerFlew with Qantas Airways-Jan 2026
leave time to get to next gate. some are a long walk.

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.

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.

Check in was easy through self-check-in kiosks just like domestic flights. Staff onboard were fantastic. Some "book the cook" good options weren't great, others really good. Entertainment options a bit limited to what I've experienced on Qantas. Overall a good flight though, especially for the price.

Could not really fault anything. We had a really short time between flights (about 45 mins), and had to get across the other side of the terminal. But we made it and crew were helpful. Food was good and service for the kids was great.

Small twin prop plane. Basic flight. Food was half a chicken & pesto sandwich. As the flight departed after 12pm alcohol was available. No on board entertainment. No wifi services.

I liked the refreshments as the flight was short and the free WiFi. The seats were comfortable.

Although the flight was delayed and out of their control, we boarded and were underway in no time. The crew were great, the service A1 and the meal was superb ( I had the chicken dish). I would fly with Qantas again, anytime. Noel Swift

Overall, it was a very good experience. I would have given it a 10/10, especially based on our flight from SFO to Melbourne. The cabin crew on that flight were wonderful and incredibly attentive. They took extra care when setting up our beds so we could sleep comfortably without being disturbed. Dinner was served promptly and smoothly. I woke up quite late, when the flight was already preparing for landing, and the crew still made sure I was taken care of. They brought me English tea in a proper cup, and when it was time to prepare the cabin for landing, they thoughtfully transferred it into a takeaway cup so I could continue enjoying it along with some breakfast. Those small, thoughtful gestures made the long flight feel much more comfortable and special. The service from the SFO to Melbourne crew was truly excellent.

From start to finish, every part of the experience was outstanding. The care and kindness shown to my 95-year-old mother was exceptional—truly 10 out of 10. From the assistance she received at Sydney Airport while boarding the plane to the help she was given when arriving at Wagga Wagga Airport, every staff member was friendly, professional, and genuinely caring. They made her feel comfortable, safe, and well looked after throughout her journey. A heartfelt thank you to everyone who helped make my mother's trip such a wonderful experience. Your compassion and dedication are greatly appreciated.

My flight with Qantas was excellent, the crew were exceptional, the food was very good, and the seats were surprisingly spacious and comfortable. I was extremely disappointed when my checked bag did not make it onto my connecting flight, but was pleased with the ease of filing a report of a missing bag with Qantas at the Auckland airport - there, my pleasure ended. I can see, with an apple tag on my bag, that it is still in Sydney and has not moved in more than 30 hours. I shared the tracking information with Qantas and was assured when I filed the missing bag report that my bag would be delivered first thing the next morning on the next flight from Sydney to Auckland. Qantas' missing bag tracking feature still lists its status as "searching for your bag, check back later" more than a full 24 hours after filing the report despite my having shared tracking information, a photo of the bag, and calling the customer care line and being assured that an "urgent action message" had been sent to the team in Sydney. The lack of communication from Qantas' customer service department and the lack of action after an incredibly expensive business class ticket price is outrageous and has, definitively, affected my willingness to consider flying Qantas in the future, much less on long-haul international flights with high cost airfare.

Going from Sydney to London on a single flight number was very convenient, not having to worry about changing planes. Entertainment system on A380 economy cabin is very dated. Lavatories are small. The self serve refreshments have been significantly reduced since the A380 first started.

It was ok, but not what it was like 20 years ago

Great food and good entertainment options for the long flight.

It seems that qantas are trying hard to regain their status as Australia's premier airline. I only flew economy but happy with the service entertainment, food, configuration everything.

Tv didn’t work and left the gate late but everything else was perfect.

They gave us some Tiramisu that had no business being as delicious as it was! They were continuously attentive and provided a great environment to welcome us on our trip.

Online check in and seat assignments are terrible. All 4 flights

it was great honestly for the melbourne flight a kit with blindfold and slippers was probided to each passenger on the seat and the food was really great will definitely recommend people take turkish airlines for travel not just on the sin-melbourne route.

Customer service was poor everywhere. In particular in business class lounge. Stewardess were however excellent. No ability to order more than one dietary restriction in food that created awkward situations when I was offered bulgur due to being diabetic as I was also gluten free

The fully flat bed in business class on the 777 is a little narrow, and the 2-3-2 configuration is now dated, but otherwise a comfortable and pleasant flight. It’s hard to beat the value too.

Make sure to request a vegetarian meal in advance. They printed out menus for all passengers with the options but by the time they were halfway through (for breakfast and dinner), the vegetarian options were already all taken.

Temperature in plane in both segments was warm. Otherwise, great experience

I requested a special meal (kosher) several months ahead of the flight . It was listed on the Turkish air website that I had a kosher meal. In-flight, there was no kosher meal. I was not able to eat during the nearly 8-hour flight. There also was no kosher meal on the second leg of the trip. The flight attendants said there was nothing they could do. They had no idea why the kosher meal was not provided. Very bad meal service.

Overall very comfortable experience. Friendly and helpful staff, the bathrooms were maintained very clean on the long flight. I had requested vegan food which was offered, but honestly was not the best tasting food. Most of the food was cold foods lacking flavor and variety. Appreciate that your airline is trying to accommodate diet needs.

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

Boarding was not as per sequence Light snacks were not available Window had hair oil stains and water condensation

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.

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.

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!

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.

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.

The smells on this plane were disgusting. So many sweaty and unhygienic people i couldn't stand it. I dream of being anywhere else in the world when I am on a JetStar flight they suck.

One of the better flights I’ve had w Jetstar. Smooth boarding, early take off, on time landing, very courteous crew, clean plane.
