Nothing more to say. I was completely happy with their services.

Nothing more to say. I was completely happy with their services.

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.

Crew was good. Sometimes food was eh. The spaghetti is gross for me. First time i got food, they didn’t provide utensils so i ate with my hands. I was hungry. They gave it to me 20 mins later when a crew member came by. I would fly with them again. Nobody is perfect

Again on this leg the WiFi wouldn't work. The seats were comfortable with adequate cushion and space between seats for my legs. Very nice 3-hour flight.

My luggage was lost and didnt arrive in manila yesterday. And until now im still waiting for the confirmation if my luggage is teady for pick up in terminal 1

Organized boarding process, superb food, lovely crew, even arrived early!

More seat space More bathrooms Charging outlets Plane was old

It was easy going check in was easy and pretty fast entertainment was up to date on movies and food was ok

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.

It was a pleasure to fly with EVA airlines from Taipei to San Francisco.

The quality of food is going down comparing with old history of excellent food. It was cold and a bad quality. The crew is always excellent and caring.

Very bad service and food variety will never come back again

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

This777-300 is configured 2/3/2 for Biz class straight out of the 80s!!! Not to mention seats are narrow, bed does NOT FULLY RECLINE FLAT as advertised, and purser didn’t know that!! ARM REST HAS A REMOTE TABLET ON IT FURTHER CONFINING THE ALREADY NARROW SPACE!!! WHO thought this was a good design?? After flying the new A350-900 biz class Montreal to Dubai , this was a total let down!!

Child’s meal was great along with other nice touches for kids.

Premium economy was worth it-comfort was definitely better than economy class. The seats were more comfortable, blankets and pillows thicker

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.

The entertainment could have been better, better choice / better headphones, but overall very satisfied

The friendly staff. They kept time. Was suprised to get some drinks.

We did not even get on this flight as the plane never left London. I missed the email that was sent mid morning USA time, so we were not aware the flight was cancelled. There was absolutely no help from the staff at the Norse check in gates, we were told to take a picture of the board they were holding up, to try and claim our money back. We were told to book our own flights to London which ended up costing $10000 due to the last minute. And now we have to return to Miami in 2 weeks. I am not holding my breath about getting on board for that flight either.

Great experience. The flight was smooth with very little turbulence. We were in premium classic, so lots of leg room.

Didn’t know you had to pay for earbuds and food on flight. Sounds awesome and better way to not waste food or items. Comfort of flight is was amazing other than that

Unexpectedly was surprised with the space on flight in economy and the price.

I was not expecting having to pay for headphones, water and basic food in a 9 hours flight. Price for this flight was as high as any other, still I had to pay 4 lbs for a can of sprite. On top of that flight attendance gave a bothered look when I asked her for some ice for my soda. She reluctantly when to get it, brought me literally 3 cubes and walked away without looking at me to avoid another request. I couldn’t believe it. She was soooo rude. I will never book on Norse again and I will let everyone I know about this. Unforgivable, very bad customer service.

Great crew. Customer support is pretty much non existent. I had 2 tickets that were not used, the flight was overbooked. I think I should have been reimbursed for the unused tickets.

The movies were super old. The crew did not offer WATER???? 5 hours os flight and did not get WATER? Norse is the worst company I ever used and never will use again.

Why call us to board if we’re going to be made to stand in the tunnel for 20 minutes. Really hard for people with little children. Plus it took me ages to check in because my seat in Premium was overbooked so I didn’t actually have a seat. I did end up receiving my seat in Premium but there was a lot of stress and confusion beforehand. Hope is it possible to overbook seats? Especially in Premium!

Service and food was amazing. Aircraft configuration is weird - stare at a stranger at take off and landing, during flight someone is crawling over your seat. It was lame.

BA Canceled this flight and put us on a flight leaving Aberdeen at 8:00 PM, delaying our return to the states by a full day. The cancellation caused us expenses in both Aberdeen and London and BA was completely unhelpful on the phone and at the airport.

First time flying with them! Loved it! Specially the schedule from Miami and being able to come back directly to New Orleans :)

They lost my luggage on my way to Namibia (I was unable to review that flight as I was in the bush/off line) It took 3 days to get my bag and I had to pay $375.00 to have it transported to my location as it was over 100 Kilometers from that Airport and the local Airlink carrier would not got that far.

Unable to check in online until the morning of flight. No early baggage check available nor any BA personnel present. Poor customer service.

Boarding process was chaotic. Confusion over Boarding gates: gate 55 or gate 56 ???. Unnecessary standing in long lines to board. Better to call out Boarding groups one at a time and everyone else to sit. Airline only has 2 Boarding groups 1-3 and 4-9. That causes over crowding and chaos

Lady next to me was coughing profusely the entire flight, other lady moved seats because of it, 8 hours of that during an overnight flight is a bit much.

We waited all day on a delayed plane. More than a 6 hour delay which caused us to miss all connections and spend a second full day traveling. Also missed a day of work that i hadn’t planned on.

I liked the air hostesses, but no wifi was available for flight. my original flight was canceled and rebooking was difficult and no reason was given for cancellation. Business class cabin was nice and spacious.

We loved our flight attendant (Emma, from Scotland), the meals were perfectly spaced out, and the in-flight entertainment was super generous and delightful.
