Can’t complain Only downside was the Kiosk passport check and customs clearance at Melbourne. When will they improve that service🤔

Can’t complain Only downside was the Kiosk passport check and customs clearance at Melbourne. When will they improve that service🤔

Similar to Hyd->Dubai this too was worst airlines. Bad seats, bad seating arrangement which created lot of confusion since family member were not given seat together. However most of them changed the seat and got with the family. Cheap tactics by Emirates.

The staff on board were excellent. Kind, thoughtful, helpful - not just with me but with others around that I observed. Wonderful service.

One of the female staff from the cabin crew, forgot to ask us about what we want to drink and focused more on other specific people rather than treating everyone politely. I asked her about the drinks to which she said oh I forgot.

Very pleasant.The crews are very helpful.Food are very good.

Except for the uncleaned tray, and the delay in serving food for our section (which may have been due to the location of our row) everything else was good. The crew were very professional and responded to our requests promptly throughout the flight. We as a family were not disappointed by Emirates.

It was great, a little more leg room would have been better particularly since we were in premium economy

The boarding process was smooth and the stewardesses were nice. Some delays with drinks at the end of the flight, but no issues.

Very uncomfortable aircraft. No free entertainment or drinks. Food okay. Won't fly with them again.

Excellent comfort and entertainment. Service poor..Food average with little choice.

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😉

The flight was mostly fine, but I really wished that seats had an outlet to charge devices considering the length of the flight (15 hours there and 14 hours back).

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

Terrible. It’s like they are stuck in the dark ages. I brought a standard carry on suitcase and a back pack - I was told I could only carry on 7kg per bag - in business class, I was forced to remove articles from the suitcase and put them into my backpack! That’s the most ridiculous thing I’ve ever encountered in all my years of flying. The two bags weighed the same amount but one could not be more than 7kg. Holy cow.

They used Thai Smile plane, which is a smaller model and used to service only domestic flights; hence, the plane is small and quite compact. No entertainment on the flight. While boarding was delayed, it was done in a quick manner.

I give EVA 5 stars in every category. I enjoy this airline and it's great team of employees. I always highly recommend EVA to friends and family and everyone.

The flight was delayed going out of the gate at BKK that made it a difficult challenge to get through immigration transfer at tapei and make it to my departure on time. This appears to be a recurring issue. The flight crew and cabin crew were excellent. The food was very nice.

The boarding efficiency was good. A couple of the flight attendants did not seem in the best of moods. Overall it was a good experience.

The setting configuration of the aircraft stinks. Nobody should pay business class fares and be so uncomfortable. The design of facing fellow passengers is a brilliant nincompoop.

Entertainment is limited with a relatively old catalogue. Wi-Fi never works and the cabin and lavatory had evidence of a lot of scuff marks and temporary repairs. Nothing unsafe, but a bit tatty in places.

A few more inches of legroom is all i ask

One of the best Qantas business flights I've had. Quality product

Business class points redemption - good value for points paid, dubious value if out of your own pocket, domestic class business product okay for this length of flight. The flight left and arrived on time, crew were good, aircraft was a bit old and tired, but still miles ahead of their competitors in Virgin and Jetstar.

Airline running better than post Covid, proper boarding process now implemented, some aircraft feeling a bit old and tired, crew fine, online experience better.

Five hour flight instead of four hours due to westerly headwinds which wasn’t the fault of Qantas !

The wifi was out. Otherwise it was great flight. Richard, as CSM, was excellent.

Was bumped to a later flight because of inefficiency on part of the airline.

The Emerits/Qantas flight was cancelled to Wellington. We need a refund. Had to buy another airline ticket. How do we get the refund. Still not in Wellington.

Delayed QF59 flight once again, Qantas doesn't fail in maintaining there delayed departures and arrivals. USB points do not work nor do the power point sockets on the plane, Qantas staff admitted that on the flight. Don't expect to your charge devices. Saving grace, was the ice cream. Bottom line, if you expect to fly to HND and make it on time avoid Qantas and if you're interested in ice cream - visit 7/11.

Pretty excellent. I don’t know what the pilot could have done better with the bumping ( there was a storm) nor what happened to my ears coming down into bendigo. It doesn’t happen coming down into Sydney just the return flight. I wonder why?

Overall I had good experience with China Southern airline. Nothing to claim. I hoped they could improve the meal quality that is.

Wow very impressed by the quality and attentiveness of service of China Southern. Lived the blankets! Will definitely fly with them again. Despite language barriers, a few attendants know enough English to understand our rudimentary Mandarin and respond to basic questions. Although they don’t explain the beverage and meal service on the website or ticketing documents, they offered regular beverage cart and snacks during the beginning hours and end hours of the long, transoceanic flight. A full meal at the beginning and end of the flight as well, and a midflight small sandwich (dinner roll sized) but we weren’t hungry and didn’t try that one. The expectation is that every sleeps during the middle of the flight. We were on a “redeye” departure from LAX with a morning arrival in China, so I don’t know if this service pattern is the same for other flights. The domestic flight we took from Guangzhou to Harbin offered conventional refreshments and meals like a US flight service. Note that they didn’t offer diet sodas. If you like to stay hydrated, I recommend bringing plenty of your own. It is served in small cups like any other drink. You can ask for a bottle but they’re tiny - about 6 ounces.

China Southern was not the problem. I booked my flight through Kayak and also received a booking reference and alert details regarding departure time and gate numbers… however Kayak NEVER actually booked my flight! We were stranded at the airport without a flight for a long awaited holiday!

The connection between LA and Atlanta was too much stress

Terrible boarding experience,,food is very poor that I I . Never going book this airline again.

The crew were kind, patient and responsive. The service was excellent, even though we travelled the cheapest economy class. We arrived at our destination 40 min early, which for a 15+ hour flight is a great bonus. The boarding seemed a bit "loose", but got us boarded on time, and the plane was off exactly @ 0:30 hrs.

The airport didn‘t give me the ticket. I called customer service to ask for a refund but they kept giving me a perfunctory response and refused to refund me.

The flight was delayed hours and most flights from CS are always delayed. Plane was efficient and got us home but not the best food and no entertainment system at all.

Not good - chair back could not move back for premium economy. Not worth the price

The back of the chair - premium economy could not move back - not worth the price

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..

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
