Food was excellent.. better if there are more movies selection.

Had picked seats while booking tickets but airlines reshuffled the seats without informing and we were again left with the worst possible seats on the return journey. terrible experience.

Overall the airline tried to give excellent service. The wheelchair service was bad at SFO. My baggage was also delayed but I thank them for taking the trouble to find it and deliver it to my home.

Airline should consider adding a small meal at the last leg of the flight, right now there is 7 hours of no meal break.

The food wasn’t good at all. I skipped meals .

Loved the airline with the exception of their carry on limitations. They enforce a strict 7 kilo limit for carry on baggage which is ridiculous. We traveled from SFO to SIN with carry on with no difficulty yet when we checked in Delhi they forced us to check the carry on bags. The weight of our carry on bags were 11 and 12 kilos and while they exceeded the limitations set by Singapore Airlines they were well under weight limitations set by may other carriers. Interestingly my wife and I were each allowed two 22 KG bags to check in addition to the 7 kg carry on for a total weight of 102 KG's. Our total weight with the one bag we planned to check and our two carry ons was 46 kgs.

Crews were very caring and polite. Washroom was surprisingly clean. Overall experience was good , only food choices was very limited. Thanks

Food option Hindu veg to Hindu non veg request was unheard

A 16 hour flight from Singapore to Los Angeles had only 2 meals. It would be great to have 3 meals.

No seperate security check for business class passengers and average lounge, open air, so not properly air conditioned

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

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

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.

I give EVA 5 stars in every category. I enjoy this airline and it's great team of employees. I always highly recommend EVA to friends and family and everyone.

I enjoy flying with Thai Airways, however their B788 business class configuration is quite dated. Additionally , while the service is always friendly and efficient, I’m getting tired of the same “usual suspects” when it comes to food choices. Since it was a lunchtime flight, what about some gourmet sandwiches or some type of salad dish for the main course? The entertainment options are also quite limited and this is not unique to TG, so much so that given the short duration of the flight I ended up not bothering with any entertainment. Finally, despite signs around the cabin advising wifi available, I was unable to con-net and in fact I’ve never been able to connect on any TG flight over the last year or so - what’s the go here??

Could have been better. I prefer Thai airlines only but it hasnt been reliable.

It was good overall. At 6 foot 1 it's hard to say anything seat on a flight is comfortable but it would be nice to have more legroom. The meals were good but would have liked to get wine much sooner.

Check in was a disaster. 90 minutes and only 2 economy check in desks open. Had to rush to catch the flight.

Thai Airways is one of the best airlines in the business. Looking forward to fly again with them.

Efficient like all the other flights with them. An outstanding budget airline!

Flights were delayed, Food was good but only 1 meal instead of 2.

Food was good but only 1 meal and 1 pie, instead of 2 meals. Both legs were late.

An overnight Doha to KL. Great sleep, good service and tasty food in business class

My experience with the flight was okay. My experience checking in was absolutely terrible. I was told I needed to change my e-ticket number to check in because I missed my flight in PDX. Even when shown the itinerary, they didn't budge and sent me to KLM across the airport. KLM wasn't open until 8pm and my flight was at 7:30pm. Nobody made accommodations in any way to get me to KUL. To add insult to injury, they rescheduled my flight to the very next day, creating a very long layover and did not offer any hotel stay. After this, even worse, I found out later they delayed the first 7:30pm flight to 9:10pm. Meaning, I could have still boarded but they refused to even try to get me on the plane. As a result, I missed a day of work and lost pay for the day. Also, when I went to get my luggage, it wasn't there. It was STILL in Singapore. They had from 5:30pm to 5am to get my luggage onto the plane and they still couldn't get that right. This is the worst experience I've had flying anywhere in the past decade I've been travelling.

Orange juice change to mineral water . Should keep the orange juice.

Entertainment system was too old, crew were unorganised during boarding

No recognition for one World Emerald member. I got row 1 in business class and it was pathetic. No leg space, cramped space, less recline

On-time & very well priced. All you need on a short flight.

The flight is awful, food isn’t very tasty or good, entertainment sucks

Flew business class. Our luggage was the last to arrive at the belt; 15 minutes after the last bag. Sigh.

Friendly staff but otherwise a typical no frills airline. The sets are extremely cramped

Flight delayed for one hour last minute change the gate this is something new? Wak all over the airport bit fast bording to flight smd miss my meeting in kuaa lumpur is the year end meeting no internet in flught which is not good Anyway overall is good thanks to the crew on duty Un able to check in on line and choose the seat thatbi wanted and in flight meal too unable to purchase rrally sad Should get priority seat in next booking

I had a wonderful experience with this company. The staff were all very friendly and helpful. Our pilot was skilled and clearly experienced. The value for the price was excellent. I would definitely recommend them.

My flight boarding was interrupted as gate staff said I needed visa in advance for Vietnam....

should remind people who cough must wear the mask. A few persons surrounding keep coughing.

They didn't have a single blanket for hire for a long haul overnight flight. This wasn't good enough even for a budget airline

No complaints. Made it on time with a minimum of hassle. Some complementary soft drinks would have been nice tho.

Actually my flight from Hing Kong to Kuala Lumpe has been cancelled and I don’t see the refund of my airfare. Thats my comment of your Company and please follow up。

I don’t travel I need my ticket back until now am with so many communication daily to get my refund

100% dislike due to last minutes flight cancellations and terrible customer service experience. Do notice us early at least 24 hours before departure time.

Paid for the seat 17D. I found that that seat has no lean back facilities

Flight was short but turbulent giving uneasy feeling :( ; although views were mesmerising ;)

Flight boarding experience with journey was smooth; can describe it as a less to minimal turbulent flight!

I paid 675£ for LHR-BOM-BKK (return flight). They charged so much money but provide very less food/drinks as compared to another airlines. Never ever fly with Indigo.

Just fly from point a to b. rest holds zero stars. And with zero competition, what do you expcect

Flight was delayed 110 mins.. Crew on Ground or in Air had no regrets.. No apologies... Very poor boarding process... Awful food and beverage choice.

Flight was delayed and due to this we almost miss the connection flight

Although we took the XL seats with more width, we found that you do not have a seat in front to stow your personal item, nor can you stretch your legs. This is not the best option for a comfortable seat. Boarding was timely but disorganized without any row based entry.

Flight was delayed and also lots of mosquitoes on the flight

Flight was delayed by 1 hour 20 minutes. Boarding experience was pathetic, even arrival got delayed due to lack of ground staffs.
