The consistency with Singapore Airlines is fantastic. Crew are always brilliant and food delicious in business class

Best airline I think. No problems with anything. Crew were great, no problems with the airline food and entertainment and a smooth flight.

Service was top notch and the attention to passengers is great. Takeoff and landing was on schedule. Food selection is good

I was in a middle seat where I felt a bit too cramped otherwise the trip was good

Airline should consider adding a small meal at the last leg of the flight, right now there is 7 hours of no meal break.

The business class seats were very uncomfortable. When in lie flat position my legs were very restricted.

Excelent service and plenty of food and drinks during the flight. Flight crew very attentive to our needs. Leg room between rows are very disappointing.

Construction at PDX resulting in very lung walk from the rental car to the gate. SFO, extremely long walk between terminals to get to connecting Singapore airlines flight. My smart watch recorded a total of 3 miles.

Crew and service was excellent, but passengers should be offered a welcome drink before take off which did not happen. Food was very good. Unfortunately the lie-flat bed in business class was one of the most uncomfortable I have experienced. The configuration forces you to sleep with your legs at an angle instead of in a straight line, plus there is very little padding on the bed so it wasn't possible to sleep for more than 2-3 hours on an 18 hour flight. For what the airlines charges for a business class ticket their hard product leaves a lot to be desired.

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

Not much of anything could have been done better unless I had a first class ticket. I was literally 15 hours with an airline in the economy class. Very professional friendly and attentive crew. Good airline food, clean cabin, seating area and bathrooms. I've been 4 times back-and-forth with Cathay Pacific, and I would not choose another airline for this trip. Five out of five stars.

First time tying out business class with this airline, hat a disappointment, never returning. We didn’t get the meal as requested from Singapore to HKG flight. While meals served connecting flight, crew takes meal order based off passenger membership status by giving the. Priority selection of meals. It was a battle, plain disappointment, not worth the hype, price, class as categorized/ advertised

If my return flight was not so much better, I would have given an excellent review.

My connecting flight was canceled or never existed. My stopover went from 1 hour and a half to 10 hours. It was a long day that I wasn't prepared for and it would have been nice to know that ahead of time. Cathay is great though. Great staff, entertainment and food.

The only problem was my connecting flight to Chiang Mai on Hong Kong express that I booked through Cathay Pacific was canceled and I was never told about it. I was rescheduled on a flight 10 hours later. Very long day at rgr airport in Hing Kong after a 13 hour flight but that's OK, I understand things change but I think I should have been told. I would have prepared myself for a long wait. Great flights all around though. Thank you

Overall pretty good experience. It would be nice to have caught the attendants even they were flying down the aisle with snacks, and if they could cater to multiple dietary restrictions (bland and no lactose. The customer service chat is a bad experience), but otherwise no complaints.

I was only given 2 meals, and my screen showed that there were 3 meals. Second meal was 1-2 hours late according to the screen.

Check in process at the kiosk, crew in flight and overall comfort was good. Food selection could have been better. Flight from Hong Kong to Los Angeles did not have any vegetarian main course option, it was either sea food or chicken. Being a vegetarian I could only eat yogurt and fruit. Most international flights have one vegetarian main course dish which I found missing in Cathay Pacific menu.

Paid a premium a have a shorter transit time in Hong Kong, but Cathay pacific rebooked me and ended up waiting for 10 hrs in Hong Hong airport.

Great. Efficient boarding process with the face recognition. Plenty of cabin space for luggage.

Couldn't access entertainment on app as said in an email

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+.

After already paying for excess luggage prior to flight, i was advised AT check in that i had to pay $816 or forfeit my flight! The lady at the counter was SO rude and had already started offboarding me when i said i would pay it after asking her three times for the exact amount! Have lodged a formal complaint yet heard nothing. Will not ever travel via Qantas again

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 service was good but the food was a NO

Crew and food was good, ok leg room if you don’t have a big box under the seat. And the seats are so narrow (I’m only 70kg), will consider an alternate airline next time

Paid $10 for wifi for full flight duration and the wifi wasn’t available after initial 2 hours

Awesome hospitality, awesome staff, awesome food & awesome travel time. Thanks

Boarding from DOH to SYD the Business Class were pointed in a separate gate but no one there to receive us. Otherwise it was ok.

The flight was delayed and one member of the crew was a bit rude. But apart from that all good.

My entire row did not have power for the full duration of a 14.5 hour flight. Could not charge any devices such as laptop or phones for the entirety of the long flight. The flight attendants tried to remedy the issue by resetting the power, but were not successful. The only other solution provided was to move me to another seat on the plane which was in the middle row. I had paid for a “preferred” seat that was a window seat. This was a downgrade being offered due to the power issue.

Not sure how we end up with American Airlines instead of Qatar Airways. From Philadelphia to Qatar they boarded us then they asked us to unload. After 30 minutes later they board us again. The inside the plane it was burning hot and we were sweating like crazy. Crew members are absolute rude. The way they served the passengers were horrible. One of the crew members hit my knee with food cart and kept going. I was holding an ice pack for almost 2 hours. I am still with the pain.

Terrible experience resolving missed connection after flight was delayed. 3 hour queue at transit desk, not enough staff, no organisation, worst ever flying experience.

The staff was the best I have experienced as a frequent traveller in a long time.

Flights were delayed, Food was good but only 1 meal instead of 2.

Food was good but only 1 meal and 1 pie, instead of 2 meals. Both legs were late.

We are row 11, when the crew came to us, only one meal choice was available.

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

Comfortable seats in economy, managed a few hours sleep in an o night flight but the food was terrible. Surprising as Malaysia airlines has been good in the past. Service was mediocre this time too.

Vast improvement needed in customer service. I couldn’t get the drink of my choice during both meals (i.e. sparking water and Diet Coke). I had used plastic cups falling onto me from the tray. No eye contact when they thank you on the way out signalling an insincere thank you.

Jia yung was the flight attendant that made this a miserable flight.

The flight isn’t great, as the plane has faulty with light and noise. It blinks and make noise for 8hrs non stop! Causing health and sensory issues! Causing Hazard matter to all 3 babies that on bassinet seats. This matters affected 12 passengers and the most horrible flight I ever experience. Have been flying with MAS for more 30yrs and this is the worst! Very disappointed

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
