Great service but food taste and options have gone down a few notches.

This airlines is always my favorite. Very consistent customer service and food is good. My last flight with them, I had no idea we landed because it was just that smooth of a land.

At least it was not very cold inside the plane. I noticed there was now a bidet in the bathroom and that’s good! I didn’t like the window seat. Flight was smooth except for 1 turbulence. Plane was on time. Thanks. Food was not that great. Miso and green tea were good! As usual movies were old and there were no changes.

The food was not that good. I liked the miso, green tea, and ice cream. I wasn’t able to put my carry on bag under the seat in front of me. The flight was smooth. Please expand your choices of movies especially the new ones. I can’t choose any of those films. They’re old.

Food is lagging. Very poor choice. Like vending machine fast food.

Please change the menu more often. The beef is not tender, more choice in ice cream flavor. Dessert is not good too.

I didn’t like the check in process I had to check in at the counter took too much time . Didn’t give the upgrade my seat .

It was one of the best experiences. The staff were amazing. JAL is my second favorite Asian Carrier I have flown on. Korean Air was my first. Thank you JAL for bringing me home safely and for such an amazing staff and service.

JAL is quite nice in business class. Comfortable, spacious seats. Their entertainment, especially their film selection, isn’t that great though as their are not many new releases like some airlines offer their first and business class customers. . Food is excellent and the option to order on demand is always quite nice, which JAL offers. Flight attendants were very friendly and kind. Overall very good experience with JAL.

Very comfortable unlike my first trip where they switched my flight from JAL to AA which was a disaster!

My overall experience with Singapore Airlines is great. Will definitely fly Singapore airline again.

Good flight. The food was served a bit late, hence a hurry to finish before landing. Excellent crew and service

Excellent meal served with real utensils, cardboard served hot meals instead of plastic utensils and plastic covers. Quick service, friendly and accommodating stewards.

Seating cramped; close to toilet, foul smelling and noisy, very unhygienic and disease risk Free and paid Wi-Fi NOT accessible at all - misleading advertising Very expensive sunglasses disappeared from back seat pouch. Coffee disgusting and cold

When boarding, after business class should be premium economy, but economy class already lined-up at the gate blocking premium economy to board. Singapore airline crew should done a better job to organize this chaos :( Thank you.

It seems paying premium economy does not make difference with economy. No priority boarding, not worthy paying extra$$$ for premium economy.

They were able to assist my elderly father and myself after not being able to check in to scoot. The counter service was phenomenal. They did what they could to get us on the next plane so we could catch our Connecting flight. Scoot closed early on us so we ended up missing our flight.

They are great with every aspect of customer service. Helped my elderly father and aided him with using the restroom.

The stewardess was very helpful all the way. My seat had an issue with headphones and after the replaced and gave me a new pair and noticed it was the seat I got a new chair to sit and a great ride back home

Due to the delay of my first flight, my connecting flight with JetBlue was canceled by Singapore Airlines, but the JetBlue crew was very accommodating and rebooked a seat for me. The crew was very nice and had good attitude.

This time is good . Don’t cancel flight with out early notice .

Very good experience, considering the short flight the meals were served promptly after takeoff.

X class seats in row 3 with the new configuration are very poor in fact I feel 3B and 3E should no longer be considered as X class seat as there is no forward seat pocket available to these seats and greatly reduced leg room due the intrusion of the business class armrests/table module

It was pretty good. Everyone friendly. Like all airlines, the draconian limitations on baggage and weight and not giving even a free soda kind of drags down the experience a bit.

Last 10 minutes boarding they canceled the flight and didn’t organise anything

Estheticly the plane looks great, although the seats are way too upright. If the seats were just slightly more reclined then the comfort level would increase tenfold. I had the stiffest neck after just a short flight due to this. A nap was almost out of the question.

Cabin crew were very professional and welcoming. They certainly appeared to have lifted their game. Congratulations

I know not directly a Virgin "thing" but I hold Virgin responsible for their subcontractors. Had to wait 45 minutes waiting for baggage at PER before the belt conveyor even started. This is unacceptable and hopefully Virgin engages with whoever to pull their fingers out. I realise PER staff are generally slow at the best of times but this was ridiculous. Maybe more seating for those waiting, a cafe in the baggage area for a light meal while we wait or at the very least a troop of dancing girls to entertain the punters while they stare at the conveyor belt start light almost willing it to fire up.

Very poor. Flight was cancelled due to captain exceeding hours. Told to fend for ourselves for 12 hours until a new flight could be done. This meant overnight accommodation in Hobart. Next plane was delayed and no food onboard. No apologies from Virgin. Extremely disappointing.

Flight was cancelled due to a mechanical fault - Virgin rebooked me on a flight 6 hours later so I cancelled and flew with another carrier

More facilities to transport to the gates......felt too much walking distance

Just happy I flew Qatar Airways awesome no wonder they are #1 in the world right now! The food was just delicious, very courteous, professional crew.

It was good no problems made it on time for the next flight overseas!

It was a really long flight from Doha to Philadelphia and it was overall a good one. The one area that I would comment on is that there is a lot of single-use plastic and disposables in the meal service for American Airlines. It would be great to see more circular options in the meal service to reduce the amount of waste.

Suddenly Flight has been change by Qatar and there’s no information is there of us from Bom to Doha and counter person is behaving like Qatar owner next I will not buy Qatar and I will not suggest anyone to fly in Qatar

The crew was fantastic and the over flight was perfect as well.

They shld provide food. Between food they are giving 10 hours gap which is toooo much

The crew was great and the food and liquor offerings were good. Seats were a bit cramped. Flight arrived early at destination. That's a plus.

All over with Qatar airlines my experience was really bad due to delays and then putting me on different airlines and after 8 hours of wait I had to listen to their is no plane to fly for another 24 hours. Wore experience ever.

I had already opted for Vegan food before 2 months yet they say we have no record for it,

Initial flight was cancelled so moved to an alternative flight. As a result, stuck in a middle seat. Flight then place in holding pattern prior to landing resulting in a very late trip home.

There was nothing I didn’t like, prices a little lower would help

BA Airbus A380 BC upstairs had 2 3 2 layout. The seat was comfy but access for those in middle or window seats had to climb over others fest to get to ailse when seats in bed mode. The layout was not nearly as private as other layouts. The staff was amazing as well as the food. Most airline food is average but this was restaurant quality.

Following a marathon flight riddled by delays and changes from Santiago, Chile, my flight to Melbourne from Sydney was on schedule but I was transferred to the next flight. The reason by ticketing and the floor manager was I missed the entry to flight by one minute! That's right, the emphasised that if I was 1 minute earlier I would be on the flight. I asked what was the point them emphasising 1minute overdue and how that helped me or the situation. They didn't care at all. Replying that if it was one minute earlier they would've done something and smirking delivering the information. Australian's do call Australia home, Qantas calls Australian's suckers.

1) crackly headphone jack 2) one of the emergency seats recline. Usually second row does. But in this case neither did 3) food was scrambled eggs or fruit. 4) fruit should not be the option to eggs 5)miserable unpleasant crew not a smile. Thought that was a virgin thing

Qantas are unable to service and unfit for purpose, they cannot transport Australians on time to overseas destinations. On top of the inflated ticketing, the Sydney flight to Santiago was impacted because the plane was delayed arriving and then further bungling by Qantas admitting the ground new ground crew in charge of cleaning were not trained. The impact on passengers with connecting flights was tremendous and long ques of frustrated passengers waiting for rescheduling. **Qantas has become the Australian Spirit of disappointment**

The staff we fantastic and seemed to work very well with each other

Business lounge in Melbourne mediocre. Look at Emirates or Qatar, Qantas! Great friendly crew. Food was good but Emirates is a level above. Business seat good. But can’t compare to Qatar. Main reason for booking Qantas is loyalty and terrific connection via Perth to LHR.

I was pleasantly surprised with my flight to LA with Qantas. Although seats were not the roomies, service was excellent.

The service and smooth landing. Food was delicious and the staff was friendly. We arrived earlier than scheduled.
