Chaos at the gate while boarding - no clear signs or announcements

Bathrooms were amazing and first class seat was very comfortable. Food was edible but not up to the standards of other first class meals on other airlines. But Caviar was amazing! So much caviar. Dom Perignon 2015 was room temperature. It would have been amazing if it was chilled down a bit more. Slippers were amazing and amenity kit requested was beautiful. Requested Pajamas never came so can’t tell you how nice they were. Loved the design of the seat and personal storage. Suite was much smaller than other airline’s first class and tv screen was tiny and remote difficult to use. I probably wouldn’t pay for this flight again.

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

Crew were excellent and the bar service and chat fantastic. Cheese board delicious. Amenity kit good, very disappointing not getting pyjamas on this leg of the flight and needed to reuse from earlier flight.

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

the seat is quite narrow compared to others. entertainment and food were very good

Hospitality is good. Should improve on buggage handling because l lost a suitcase. Layover in Dubai was too long , 6 hours

They should resume the fast track for business / first class passengers

They cancelled our flight, rebooked, cancelled that one. We are now flying New Zealand Air and need a refund please. How do we get it?

I wear hearing aids in both ears the infotainment system is hard to hear.

Crew was very good, but could have checked on us when meals were not being served also.

We flew economy light. We did not want to check bags and we had free 1 bag, but just had back packs with small personal item. Try as we may could only get bags down to 17lbs each. So we put 2 lbs from one bag into other and checked it. I think if someone has a checked bag allowance and chose not to use it , it would benefit both parties to bump carry on weight up to the next level of 22lbs or 10kgs. Just a thought.

I didn't have much experience with Cathay Pacific airlines because of delay and missed connections, the bulk of the trip was on Japan Airlines.

Vegetarian options should be included with every meal. Even just simple steamed vegetables and whole grains would capture a wide audience.

The bed was alright in business class. Food variety and quality were not up to the mark compared to the business class airfare.

I wish there were more bathrooms available on these larger carriers.

There were delays at boarding and landing. These events resulted in a tight transfer time in HK. Poor signage for transfers. Finally, lost luggage at final destination.

It was good. The planes needed to be updated though, they were dated and the entertainment systems were old. Service was amazing. The pre-booked meals were lacklustre.

Super delayed. Unnecessary. Need more competent people doing logistics to keep things moving on time. Totally unacceptable.

Business seats not as comfortable or private as most competitors (e.g. Qantas was outstanding), and movie selection was much more limited than Qantas or United has been recently

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.

No entertainment except on app. No outlets working to charge. Good service

It was mediocre. Honestly, the flight was late but that didn’t bother me as I had plenty of time. The only thing that bothered me is that the crew never asked to make the beds for us in business class. Maybe the crew was exhausted and that just didn’t occur to them.

The flight was over 1 hour late taking off ,when I arrived in Abu Dhabi ,I missed my connecting flight to Bangkok so I had to wait almost 6 hours for my flight arriving in Bangkok at 6:30 am ,So I missed a whole day of my vacation and my hotel room sat empty so I paid for hotel days that I was not there. In Abu Dhabi there was a woman that worked the desk at transfers that was so professional, courteous , helpful,and may I say absolutely beautiful .she got me food vouchers for my layover and was a very calming presence. Besides that I will never use Etihad again I will pay the Xtra money . I'm sure they won't read or see this but it's my "2 cents" I'll use an airline that respects me and my hard earned dollars

Nice crew , clean cabin , food was delayed due to problem with the quantity .

Kayak and Aran grant issuing business class tickets without lounge access and sometimes 1 or 2 connections in economy class. It’s very disappointing to find out that after buying the ticket. Never buy tickets on kayak and Aran grant again

We have paid premium price for a business class Cabinet and we have received the old 777 with the following apart business class that is not to standard. It was very disappointing and it’s a very bad reputation for a premium airline company. This aeroplane should be the commission from being as a business class. We will pass this knowledge to our colleagues because the quality of business class in Etihad is not consistent and it is a lucky dip that sometimes you’re getting a good aeroplane and sometimes you’re getting their 30 years old aeroplane. The crew of the aeroplane have apologise and said that they hate this aeroplane and they have complained about it multiple times as well. Obviously Etihad is putting the economy in front of the Customer Experience. For the future we will not take this risk anymore and will fly with established company like emirates.

Was so disappointing. Business class with no TV, uncomfortable seats. Had much higher expectations.

Etihad Check In counter/Station manager in Heathrow was bothering and not helpful at all. They are rude and not customer oriented

Very disappointing #1 - You have to pay extra to use the business lounge, or else you sit in the cold airport for 7 hours and fall sick #2 - Did an awful job with boarding, they turned on the "last call" notice on the monitor made the passengers come running to the gate, once the passengers came close the crew would tell them - hey we are not boarding yet, this included passengers with children also, this was happening all the time, it was pitiful to see #3 - Did not have the courtesy for the passengers in the business class, there is a reasons why people choose business class, because they need to get to work, that means sleep is very important for them, in the business class, the crew members would themselves cause so much noise by closing the door in a loud way, once the crew member does it then the other passengers are also doing it, #4 - the food did not smell good, #5 - The Abu Dhabi airport is small, so not a whole lot to do, especially when the layover is 7+ hours. #6 - Did not provide the slippers with pajamas, #7 - also the pajamas also I had to ask, only after asking it was provided. #8- Asked for an extra pillow because the pillow they provided was not tall enough, the crew member said there was no additional pillow and gave me something like a blanket, I tried my best to use that as a pillow, but my head kept on sliding and that messed up my sleep and did not get deep thorough sleep Overall the airlines did not have an understanding of how to care for the passengers, especially the business class ones. Overall it was a bad experience, I would much rather spend the money with Qatar airways, the experience with Qatar is so much better.

I didn’t have a flight because it was a fraud and you allow it. Illl never use Kayak again!!!

The ticket was last minute buy so no concerns about the pricing this time, but the crew in general could have been more accommodating, helpful.

CTU-KMG-CNX with 1.5 hr connection at KMG. Doable but just barely bc immigration exit from China is at the last flight leg, here: KMG to CNX. We hauled out of the domestic terminal to reenter at the international departures (luggage checked thru to CNX thankfully). Immigration had only two agents, even though KMG gets a HUGE number of foreigners. It took forever for such a shot line. Then security also took a while, so I just just made the connection. Recommend if you exit China with domestic international transfer, plan for 2+ hrs to avoid a heart attack. Airline personnel don’t suffer if you miss the flight, you do. Plan accordingly.

China Eastern as a member of Sky Alliance airlines should have the same standards overall of their partners, Besides the seats comforts everything else is bellow the standard for a business class travelers. A BIG ISSUE FOR NON-CHINESE PASSENGERS IS THE ABILITY TO CHECK IN ONLINE, by making so difficult or almost impossible there is no chance to get a seat assignment ahead of time then go to the airport and get what is left. THIS IS NOT a SKY TEAM modality.

China Eastern as a member of Sky Alliance airlines should have the same standards overall of their partners, Besides the seats comforts everything else is bellow the standard for a business class travelers.

2 parts to the journey. First leg covered in a newer plane with decent staff + POOR FOOD QUALITY but the second half didn’t leave a positive impression at all as the plane itself was an older built and the crew didn’t serve properly. Language is an issue with China Eastern flights as always, but unmotivated crew just makes it even bad.

Small plane with only two lavatories at the back. You must have a good plan to use it before or after the meal, if you make a bad decision, you will end up with standing in front of the toilet for a while till the food carts empty. The good thing is even there’s a slightly delayed, the plane is still arriving on time which is superb!!

The only personel that smiled at all were the flights attendants. Desk agents, lounge people none of them had a smile or even a hello. They were like dealing with dead fish. Again flight attendants were good. All other personnel looked like they didn’t want to be there or help.

good flight. food is only so so. I actually did not eat the snack. it does not look too good on the passenger next to me.

Food no variations only beef of chicken no veggie meals

Super surprised with the entire experience. Business class is incredible. Flight attendants around the world could learn customer service from these people. Simply fabulous experience all the way around.
