Other than spotty internet, great servic, comfortable and smooth flight!

I liked that they gave us a couple of meals and drinks but the meal was not good and not many options especially if we are seated in the back of the plane.

I dont know how to explain but i really satisfied

I am really satisfied with Eva Air and will definitely fly with them again.

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.

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

I had knee surgery a few weeks prior. I was using cane walking very slow. Crew were extremely helpful

Very bad service and food variety will never come back again

The flight was delayed and the service was not good. All the new serve was beef and we don’t eat beef so we ended up buying our own meals at the airport twice.

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.

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

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.

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.

Gate and boarding processes were handled smoothly and efficiently. Both (connecting) flights departed and arrived on time. The cabin crew seemed anxious and a bit stressed/rushed. Food service was OK, but the hot food dishes were poor quality.

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.

Flight and flight service was great. When a flight is cancelled, publish to all affected with email and txt. Explaining the way forward.

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

The boarding process was awful-the computers were down and there was no way to check in. Took extremely long, very chaotic and no guarantee our bags were even getting on the plane. I was also delayed and took away from any time i had to catch a connecting flight.

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.

I wish I knew in advance that the connecting flight was by indigo air

They lost the baggage and said it was deleted from the system. I had baggage tag so was able to file the complaint but there was no PIR number and update so far

I booked tickets for a family of five and specifically paid extra to select our seats together. We spent nearly $1,000 extra (around $100 per seat) for extra legroom so we could sit near each other. However, despite paying for this, we ended up being separated on the flight. This caused a major issue for our family because my parents do not speak English and rely on me to translate and assist them during the journey. I do not understand why Etihad changed our reserved seats without explanation. I am extremely dissatisfied with this experience. I expect the airline to do better, and I am requesting a full refund for the seat selection fees we paid.

It was excellent service in the snow storm gives us hotel and transportation. It will be more better if u can add one more meal because it’s a long flight boring journey. If you give extra meal time passes faster and can enjoy the trip better

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.

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

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
