Overall were very good and I was satisfied w/ all the food and services.

Food was served to different people at different times and it wasn't clear why. The crew apologized for the wait. But it felt odd and inconsistent. They could use charging ports on each of the seats. Mine didn't have any. Also, they could've offered more snacks. It was a 12+ hour flight and no snacks were ever offered. Everything else was OK.

Excellent service. I pre-ordered gluten intolerant meal and they handle it with care. They served me my meal before other people's to avoid crossed contamination. Thank you 🙏

I wish there was a little more leg room between the seats. The recline was good and seats overall were comfortable. I also didn’t like the 2-4-2 configuration.

The flight crew was phenominal! We couldn't have asked for any better. They were experienced professionals.

The crew was very courteous and professional. the flight is relatively clean and comfortable.

a completely full flight - felt quite carmped in, despite being on the window seat. Meal served could better. Surely different from pre-covid trips I used to take to and from Bangkok.

Food was just okay, need to improve for other menu variations

Wish the seat don’t have restrictions, can’t fully insert backpack all the way inside.

Wish the underseat compartment don’t have a restriction, can fit a personal item such as backpack fully like most Boeing

Food was great. More vegetarian options on menu would be great!

Child’s meal was great along with other nice touches for kids.

Emirates did great! I liked the service, the food, cleanness, and the flight was on time. Much better airline than Qatar Airways I flew with last year.

I would have liked less packaged snacky stuff, more fruit. The crew was great.

Great flight - Clubhouse met our needs, and the staff provided good service. Boarding felt a little chaotic, but given the size of the aircraft, it's always going to be challenging. Whilst the crew were friendly, the number of passengers meant that we received our breakfast items, but had finished breakfast before we were served a drink. Lunch was much better organised, and throughout the flight, the crew were attentive. Found the seats and ICE to be excellent. Disembarkation was fine, and everything possible to expedite the process was being done.

It was delayed for 2 hrs. Flight attendants were not attentive.

We boarded but due to a technical issue we spent 4.5hrs on the ground waiting for the issue to be resolved

I take emirates because of direct flights Otherwise no Cabin crew niot friendly and never friendly across the airlines Planes old inside not renewd .. this is not an issue The issue is the poor service

The 2 sockets near me didjt work i had my phone by end of the flight on low bat and had issues to book uber thereafter Electrical sockets should work if emirates does not allow batteries Baggage claim in zurich took very long

No kids provided. Instead we were told to have contacted the airline that we have kids and require kids meals. We were not the only ones who inquired about kids meals. It’s odd. Emirates and other airlines give kids meals as standard and before the adult food comes out. The rice in our meals was gluggy and under cooked. The chicken was also raw. Sadly not the best experience with Finn Air. The hostesses tried to compensate with the snacks and drinks but missed the mark by a long way. Especially when paying Emirates/Qantas prices

Hard to move and get out of my seat when the passenger in front is in recline position.

It was a good flight and no complaints. It just wasn't anything that was better than any other flight.

The crew were wonderful - if only the customers were as well behaved as the attendants!! Ha ha! If you could just talk to God and ask for less turbulence next time.... Juuuuust kidding....

Flight was canceled. I was not alerted. It was only kayak that alerted me

Flight was 2.5 hours late leaving. We spent 50 minutes of that sitting on the plane with no explanation. They did reduce the time in the air so we arrived a little less late which was something. The cheese and crackers were okay but the wine was terrible.

Excellent as always, I won't fly to Australia, and back to the US on any other airline. The flight crew is always top notch, and have a way to make one feel extra special. Thank you for your service, I would rate Qantas Airways a 10+.

Basic airline, aircraft and service. AA gets you from point A to B. My flight was delayed by 2 hours too.

No internet on flight, which makes log travels really hard.

Not great. The inflight entertainment was all on an app, and I did not want to watch a film on my phone. Also, the range of options of films was limited.

by the time they got to our row, they were out of some of the food options. games and movies were great but maybe more game options like tetris or pac man would be great

Apart from the staff at the airport who were amazing the rest of the experience with scoot was disgusting a very basic flight packed and uncomfortable no consideration to a disabled traveller. And even worse from Singapore to Vienna. All about the money. Not even a complementary coffee or juice. From the airline. The staff at the airport didn't look at me as been disabled and no help not even a wheelchair was offered. The food on the plane was cheap and tasteless and expensive no entertainment on plane and WiFi which had to be paid for was intermittent at best.

Uncoordinated boarding, seat comfort is terrible, even toilet is so small that overweight people wouldn't fit in. Baggage scam with additional fees. Stay away from this airline.

Forthright communication to the customers regarding services offered and any fees involved.

Scoot is a no frills budget airline. Do not expect a legacy airline experience.

I have taken more than 50 flights in the past year and this is the worst onboard experience that I've come across. There's always a risk with budget airlines and their creative views of customer service. Having bought a standard seat, we boarded at the assigned seat - we naturally couldn't choose ourselves as that would be extra cost. After take-off, the person in the row in front leans back their seat. As a frequent flyer, I believe this is their right, so I try to lean my seat back as well to have the same space available. However, my standard seat could not lean back, as the row behind was an exit row. As I had paid for a standard seat, not a less space than standard, I moved to the completely free row behind me. This was not allowed, as due to extra legroom, this would cost extra. Subsequently spent the next 30 mins discussing this scenario with the crew. I have no issues with budget airlines and additional charges, but if I pay for a standard seat, I want a standard seat, not one with less space. As you do not offer me a discount for the less space, do not try and charge me a premium, when I find a free seat with more space. It works both ways Scoot.

Finishes were quite worn, including our very scratched up seatback. No entertainment available, and the WiFi (even for “ScootHub”) was very slow. Crew were somewhat friendly.

Food & lower the prices. Look at Air Asia food look better & affordable

Not a frequent user of their website booking. Booked my check-in baggage and only realized that I did not book my check in baggage for return flight. The receipt was not clear in identifying that as well. Was charged exorbitantly at check in counter. Bad taste for sure when it is a business trip and not leisure trip. Baggage was delayed for more than an hour at belt back in SG.

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.

The cosmetic condition was pretty run down. The carpets were badly worn out. Even the paint on the wings was chipped and peeled! Looks like they are running these 787s to the ground..

Improved experience over our last years flight when also we flew local but on an international scheduled flight. The double processing is still unwelcome i.e. by security and then by border force having to produce a licence and boarding pass repeatedly on departure and return. Obviously suits the airline rather than the local traveller. The flight and crew were good though a helper on return was offhand having to push the wheel chair did the bare minimum we felt.

Flight on time. New plane. No entertainment screen just device. No offer of water. Didn’t order food.

Flight was delayed both directions but once in the air was ok. Boarding out of Melbourne is just a mess.

Although a local trip via international flight it was fairly straight forward albeit more checks than desirable for local travel. On arrival Perth collecting luggage the trollies were hidden in one end of the long hall.

Jet star delayed both trips with poor communication. Passengers were made to change gates often and then left to stand with no seating. As someone getting over surgery this was very trying.

Delayed twice. Poor communication and people made to change gates too often.

Excellent help with Wife needing disability access at Brisbane airport

The flight was delayed by 2 hours but the Jetstar crew were fantastic.

Late leaving and desintuon board showed ‘gate closed’ when they hadn’t even commenced boarding!

Flight was delayed more than 1.5 hours. Gate changed multiple times
