EVA canceled me out of the return flight from Manila to Spokane so we had to rebook and repay. Very unprofessional!! Still have not returned home!!

Crew are excellent. Food was good generally. Seats are small and there isn’t much leg room. Overhead bins are very small.

Amazing customer service. BUT!! It would be nice if the flight attendants SMILE a little more, I know they are doing their job, but it is importantly to smile back and be warm to passengers. Nobody is trying to hit on them, it’s just being polite. So, please Taiwanese flight attendants: SMILE MORE WHEN YOU INTERACT WITH PAYING CUSTOMERS

From checking at the airport to end of flights, attentive and caring personnel, comfortable seating, great food. I plan on using EVA again. Thank you, all.

The soft service on EVA was superb from the quick and attentive flight attendants, to the turn down service, and excellent food. This all made my 11 hour flight very comfortable and relaxing.

Flight attendants were very helpful and nice. Would be nice to board on time.

Excess baggage fees are outrageous ($250 per bag). Flight crew and planes are nice.

everything was so good! Especially Food. It was the best I've ever had! However,I requested to add mileage point to Star alliance group ANA; it hasn't been added yet.... 😞

Service in BKK was very good at answering our question about our canceled flight from Taipei to San Francisco. Did like the lead time about the canceled flight from Taipei to San Francisco and was not given the best options.

Awful had to ask for a supervisor to sit with my flight companion even t booked the tickets together weeks before

What a great trip . From check in to the upgrade we received a big shout out to Cleverson who was able to help us navigate the whole process super patient and was just one of the best customer service experiences we received in a very long time . The amazing staff on the flight who went above and beyond to make sure we were comfortable amazing food and service if you have te opportunity to upgrade it's a must and well worth it.

Everything was perfect. Staff were informative and professional and flight boarding, flying and de-embarking was smooth. I would certainly travel with Emirates again.

My baby was with me it was really good experience with emirates

Fantastic as ever. Great staff super catering and excellent service.

Flight and entertainment great. Food needs to be improved, only one choice on the menu. Staff worked well throughout.

Very good from the beginning to the end. Amazing experience

Always enjoyed flying with Emirates, flown with others but they don't really measure up. The others are cheaper without a doubt, but not as good as Emirates

The crew were absolutely fantastic. They actively asked if passengers wanted refills and if they were comfortable. I was extremely impressed.

in today's time, an airline like emirates didnt serve drinks as requested, Excuse was full flight.

Great flight - Clubhouse met our needs, and the staff provided good service. Boarding felt a little chaotic, but given the size of the aircraft, it's always going to be challenging. Whilst the crew were friendly, the number of passengers meant that we received our breakfast items, but had finished breakfast before we were served a drink. Lunch was much better organised, and throughout the flight, the crew were attentive. Found the seats and ICE to be excellent. Disembarkation was fine, and everything possible to expedite the process was being done.

HAVING ANNOUNCEMENTS FOR PEOPLE TO BOARD ACCORDING TO GROUP IS ESSENTIAL N ENSURING N CUTTING OF QUEUES, EXCEPT FOR PRIORITY CLASS PASSENGERS ON A SEPARATE Q

We still get drinks and a snack. Love the gift bags too.

business class is old but still done very well by the team.

Excellent airline. The plane was clean and the staff were very attentive

Good experience although the boarding gate is at the terminal extension hence need to leave lounge to head over earlier.

Thai Royal First is very good. Easy check in , Private room in the first class lounge and escort from ticketing to the plane. Once on board crew was very polite, food was outstanding, and the ride was smooth as silk. Restrooms were especially clean. Great Experience

I'm not interested in improving the airline. Therefore, I won't explain this in more detail. Next time I'll try a different one.

The flight (boarding) was delayed by 40-50 minutes and there was very crowed. They need to improve on the timeliness & boarding process. (They asked passenger to board in groups, but the 2nd group was standing there waiting for 20 minutes!). However, services from the crew was very good, also the food was good as well. I also found the legroom was quite comfortable.

Need to improve on punctuality. My flight was delayed by 1 hour.

Seats were uncomfortable and the vegetarian meal was awful. Some of the entertainment didn't work.

Very poor No information given to why we turned around.. No one at airport to help

Qatar Airways has gone down over the last few years.

I paid extra for seating when first booking flight to be in a comfortable economy seat They still changed it to a middle seat regardless. When I asked for it to be changed back to aisle, they could only give me one at the back of the plane in the least comfortable seats.

Top, only problem about Weather but not depended Qatar Airways. Anyway staff offered kimbo Refreshments

The boarding experience did not follow the Zones that were listed on the boarding passes. This was a two-level aircraft with many passengers. Because zones were not called out by the airline staff, there was simply a mob trying to board and it was not a pleasant experience.

It would help id flight crew were not rude and showed some courtesy. They were shouting at passengers and yelling instructions as if we were school children at lunch cafeteria!!

Nice airline. I was in a really weird seat which had extra leg room, but no basket or stowage. And the people next to me were pretty noisy during the flight, so it was hard to rest. I wish staff came around to pick up trash more often as I had no where to put it except my lap or the floor.

You are the best, keep up the good work. Thank you for allowing me and my family to fly with comfort.i am waiting for upgrade some day. Thanks again

Friendly and discreet staff. Could have done with a few more offers of water/snacks overnight. Movie and tv selection notably poor. Seats not especially comfortable

All great, because I was given a seat with extra legroom on this part of my trip.

Business class ticket should include lounge access and seat selection. The food quality and varieties should be more. It was surpirise that no dessert was offered.

I liked the crew, the food and the foot space. I did not like the comfort of the seats.

Good one but just notice that you have to ask several time to get water or coffee .

Good service. But on flight to Kochi no entertainment except in app. And no working outlets to charge phone.

Good flight. There were a few issues with the flat bed. It was some technical issues. Otherwise everything was good

The crew could have been more friendly and could have offered to make the beds. Also, Ethiad should have more vegetarian food options.

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

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.

There was not any issues with the Etihad Airways. Staff was excellent and I love the variety of movies and games that they provided.
