A wonderful new plane. Great menu. Professional service. You and your wife were completely satisfied.

Poor food on board, but seats are too small and uncomfortable

1. The entrance to boarding gate G5 (which is at a lower level) is from the walkway (which is at the upper level). That entrance was locked and there was no place for hundreds of people to sit at the upper level, for a long time as the flight was 45 minutes late. 2. The choice of movies on board was extermely limited and poor. 3. The staff was unhelpful and faked politeness.

No ice for the drinks. Only gave a half a cup of your beverage. Not enough water. I got very dehydrated.

They didn’t have ice for the drinks and only gave you half a cup of your beverage. Did not have enough water. I got dehydrated

Seats could have been more comfortable, but it was a pretty good experience all things considered

Eva air is a good airline. The seats on the way to Taipei could have certainly been more comfortable, but all in all it was a pretty good experience.

Fast boarding process. Flight was expected for a long haul economy flight

The flight went well. Everything good. Boarding. Meal service. Snack (crackers) & Drinks. (Could do with more selection like a sandwich). The seats did not have the annoying footrests (that dig into your shins when you stretch out your legs.). Entertainment was good as I watch 4 movies. Screens were bight (adjustable) but could do with privacy filters on them to prevent light from the passenger next to you shining in your face. They need to have milk for hot black tea though as coffee creamer just never makes tea taste nice.

Flights were both delayed. No luggage on arrival for the whole plane and no contact since submitting a PIR.

Flight from Dubai to Zagreb very bad cabin crew. Bad food

The crew manager let the staff down by not ensuring special dietary requirements meal were coming in drips . The poor cabin crew did not stop . If organised the cabin could take a short break ..The cabin crew were AWESOME UNLIKE THIER TWO MANAGES!

Superb experience. I hope they bring back the fast track option at Heathrow immigration.

Newly reconfigured 380 I assume. Has a new ife with usb c ports and Bluetooth connections

Inexperienced e crew, no personal greeting for gold member, not the same emirates service that I know. I take this flight almost weekly

Very bad !! My confirmed ticket got canceled with out notifying me in hyd airport , crew didn’t help us out !! They were very rude!! They made me pay for the confirmed ticket again !! Can you please let us know how I can get the refund for the ticket I paid

The entertainment selections are amazing. But the live TV is sometimes spotty. If you’re going to have it, then have it. If you can’t make it consistent, then, perhaps it’s better not to have it. The crew are always cordial when approached, but they seem to do the minimum and sit around, talking to each other in the back of the plane during the flight. I realize that delays are not always predictable, but I missed my flight in Dubai because we left 90 minutes late from Washington. I will say that Emirates took very good care of me in Dubai. But I would rather not be delayed.

Had the salad which tasted awfully spat it out but still got food poisoning 1 after running to toilet crew would not let me sit near toilets I was stuck in window seat

I enjoyed the live television programming for entertainment, and honestly everything was acceptable. It’s just that I choose emirates, because they have always been so much better in so many ways – food choices, service, accessibility, friendliness of the staff. None of those things were poor, but they have definitely slid from their position of excellence. One example would be that after the dinner meal was served, the flight attendants huddled in the back galley with the curtains closed (by the way, that’s where snacks and drinks are), and you have to interrupt them to go back there to either ask for something or to get a snack. While they do not respond in an unfriendly way, you are led to believe that you are interrupting them by coming to get a snack or making a request. Even something like, “ Yes, how many I help you?” would be a great improvement.

Extra seat belt across the chest 10 minutes before taking off and 15 minutes before landing seemed excessively safe.

The transfer from Domestic and International was a bit confusing but I am easily confused. I did not eat any food, but the food on the other leg was decent. It was nice they turned the lights off on the night flight. The plane was in good shape, but was a little cramped in economy and I am small. They gave me a customs form to fill out and nobody looked at it as I went through customs. Not a bad flight.

My case was missing a wheel on arrival Heathrow and the staff were unhelpful when i tried to get some compensation stating it was not sufficient damage, i only wish that they at some point have to deal with the same situation it put me in, maybe they would change their attitude but overall it was a good flight

We are satisfied with the cabin crew serviceand the quality of meals served.

The aircraft was really old, the staff demotivated and the overall United airline service is horrible

Increase the number of available films, including variety. All other aspects were great.

I couldnt go on this flight and lost all my money over 1,000 UK Pounds as my visa to Myanmar was not accepted :(

food poor i said chiken i got pack a pow breakfast lousey .job to explain wot it was ...

After going back and forth with the airline, they never reimbursed the airline tickets. Went around asking multiple people how to get reimbursed and kept getting put back, not satisfied with their customer service.

No working jet bridge to deplane, with priority customers deplaning last. Followed by bus to terminal.

Good staff, good intent, decent entertainment. More seat space would always be of benefit

I had first class service from them. A little late taking off, but no major problem

For a short flight, Qatar Airways offers very good onboard service.

Not good. Expected a lot more as far as excellence.

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

Just money making business. This was my fourth journey with Qatar Airways, year by year the quality of service getting poor. Food is very cheap. They have some low quality alcohol beverages. They don’t have any brandy or cognac. No toilet around the gate lounge. We have to wait until getting to the flight for use toilet.very long standing for entering into the flight. We can see the old passenger suffering.

It was pretty good overall. I just wish the crew didn't have to interrupt you every five seconds to ask you if you wanted anything, I mean that's what the help button is for. When someone is tired and sleepy and still getting their bearings, turning on DND button is maybe not the first thing on their mind.

Was required to print a boarding pass, which I'd prefer to avoid. Seat (economy x) was comfortable, service was excellent.

After going through security and waiting for the flight at the gate, there was no access to bathrooms and no place to charge a phone while waiting for the flight. But once I was on the plane, everything was very good.

Food and Service inside the flight. Airport service from Qatar is not good mainly because of lack of coordination and not used of seeing so many ppl commuting

Good airline for the price. The Air stewardess are great, nothing is to much trouble. Will use again.

Cheapest option from Gatwick £400 cheaper than Emirates and Qatar. Entertainment no where near as good as Emirates and Qatar, but saved £400 so all good.

Gatwick London-Shanghai -Bangkok.. Would have liked entertainment screens, but I know these planes are not that new. Cheap flights at the time of booking, Emirates wanted double so you get what you paid for. I would fly again with them, but if Emirates was the same price I would go with them.

We were cutting it close on our connecting flight and notified all staff at departing gate and flight attendants. From the start, we were told to check in with the international transfer desk by everyone, except for one lady who wanted to argue the time difference that was already taken into account. We also asked if we could try to exit the plane first (our family of 4 and 8 others on the same connecting flight). They just told us to check in with international transfers. We landed and had very little time to make our next flight. We were not offered any assistance or communication to the receiving gate. We ran all the way to the international transfers gate only to be turned away. I think we could have made it if we were allowed to exit and a call was made to other check in counter. After that we spent 6 grueling hours with our kids trying to rebook a flight. No food of any type of compensation was offered besides a dirty hotel room. The ladies with China Eastern at the Shanghai International counter were rude an unhelpful. We were directed to 3 different counters and waited before they said they forgot about a hotel. It was a long, miserable day. I believe this could have all been avoided.

Flight was fine, however we were not able to check in online, this adds to travel stress. Luckily check-in at Heathrow was quick, but we did not get the seats we paid extra for. We paid for a window and 2 aisle seats from Shanghai to Tokyo leg, but they changed us to middle seats. Not good :(

Couldn’t fly since they wouldn’t issue a boarding ticket. Something to do with not taking the departing flight since it was cancelled due to weather. No notice or anything about the trip being invalid. The app made it seem like I was all good for it. Never trusting travel agency

2 hours delay on the 1st plane out of the day!!!!!

I will never fly through China again. Maybe it was the mandatory retinal scan just to transfer to another flight or the complete set of fingerprints they require. There are many better and inexpensive flights to Asia if you look.

Pros: "The crew was very attentive and most good English"
Cons: "The food could have been better and there could have been a better selection of movies."
Cons: "Gate is crowded and no escalator only steps. No clear area for business class and its a fiasco boarding"
