They used Thai Smile plane, which is a smaller model and used to service only domestic flights; hence, the plane is small and quite compact. No entertainment on the flight. While boarding was delayed, it was done in a quick manner.

They used Thai Smile plane, which is a smaller model and used to service only domestic flights; hence, the plane is small and quite compact. No entertainment on the flight. While boarding was delayed, it was done in a quick manner.

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.

The flight was delayed going out of the gate at BKK that made it a difficult challenge to get through immigration transfer at tapei and make it to my departure on time. This appears to be a recurring issue. The flight crew and cabin crew were excellent. The food was very nice.

The boarding efficiency was good. A couple of the flight attendants did not seem in the best of moods. Overall it was a good experience.

The setting configuration of the aircraft stinks. Nobody should pay business class fares and be so uncomfortable. The design of facing fellow passengers is a brilliant nincompoop.

Entertainment is limited with a relatively old catalogue. Wi-Fi never works and the cabin and lavatory had evidence of a lot of scuff marks and temporary repairs. Nothing unsafe, but a bit tatty in places.

Delayed flight in Singapore caused the transfer at Bangkok to be very stressful. Fortunately, no elderly were in this trip, else it will not be possible to catch the connecting flight. There were also several occasions throughout the flight journey where some of the passengers were not wearing their seat belts despite several remainders from the stewardess.

USB charging port was not working at my seat 48K.

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??

Always liked Thai Airways but in the past they have been very expensive, not being a millionaire just yet, I will use cheaper airlines. Bangkok to London £370 11 hours 45 mins. Old plane but ok. Lovely ladies on board, very polite. Food was ok. Will always use them if the price is right.

Boarding uncomfortable. Stewardess said I would have to check my carry on as there was no room in the overhead bins. Another passenger helped me find a spot.

Any flight that lands safely is a good flight. However our leg from Helsinki was delayed 1 hour with no explanation. The delay would not allow us to make our connection to Cincinnati. I was informed by American Airlines that our Cincinnati flight was rescheduled for the following day. I immediately made a non refundable hotel reservation in Dallas. Upon exiting the plane at Dallas I was given a hotel voucher. Nice, but I can't get a refund on the hotel I booked. A little communication would have been helpful. Food on Finnair is below quality of Korean Air.

The cabin crew really looked like they wanted to be somewhere else. They weren't really interested in providing an attentive service to full fare paying passengers at all. However the Captiain's in flight announcements were relaxed and very entertaining.

Crew were professional and responsive. Food was mediocre and breakfast could do with revampinmg

Food was very ordinary for premium economy, very small portions.

i dont know WHY they call it business class. the seats are NOT significantly wider than economy seats, they just do not let the middle seats be beepked to give the illusion of more space between passengers. the seats do NOT recline any more than economy seats either. the only real difference is the full meal served to business (vs none for economy). I would rather have a wider, lie flat ACTUAL business class seat with no food for a 3 hr flight. this was pretty disappointing to say the least.

There wore nice leather like sits, in my opinion seats lay out bit tight . Crew was great they did averything possible to make averywone comfortable as possible, food was, think worst I ever head on flight, head chicken and yellow rice. Ice cream was a nic treat.

Our previous flight was delayed but they waited for us to board.

Flight was delayed, short time connection to next flight but we make it, service was good, worth to fly just to try thair on board blueberry juce. Eccelent communication with airline.

My American Airlines flight was deleted and you guys never let me know

It was ok, not much more can be said, as long as airlines/aircraft manufacturers insist on cramming in as many seats as possible....best of a bad situations, seats are simply too uncomfortable to sit in for more than a few hours. Lack of flexible headrests not a help on long overnight flights either.

Liked some flight attendants. 1 was rude I'll not say her name I don't want to get her jn trouble on my flight back to Dallas from Doha. Very rude to some races of people clearly. She needs a better attitude and bedside manners. Asking her questions and she responds "WHAT" twice rudely like I was bothering her and "is it going to be cranberry or mango juice with an attitude".

Seating is terrible, having seats so crammed is unacceptable for a 15-hour journey. I cannot stress enough how uncomfortable it is to sit in such an aircraft. Leg space is roomier in a domestic aircraft. I have not experienced this kind of crammy seating in domestic flights either in the US or other international airlines overseas.

Wasn’t allowed to continue with the purchased tickets because I hadn’t been able to go on the first scheduled leg.

Good staff, good intent, decent entertainment. More seat space would always be of benefit

Operated by American Airlines. Very chaotic and the crew was bit rough responding any enquiries. Restricted leg space.. Qatar would have been better

Just happy I flew Qatar Airways awesome no wonder they are #1 in the world right now! The food was just delicious, very courteous, professional crew.

From Montreal to Doha , we habe two complaints : 1) They want to charge for Seat Selection, claiming that the Class of ticket bought on Kayak did not cover seat selection. It such a penny pinching rule, I told them, since we paid almost $20,000 our 3 tickets , that rule should never exist. Also I reserved my tickets so many months ahead, I expected they will naturally put the family together or move somebody else to keep our family seating together. I filed a complaint, and NOBODY ANSWERED. 2) In Montreal, Qatar has an arrangement with the National Bank Lounge. It was so overcrowded and the Lounge is so bad in terms of service and food, amenities etc... The WORST lounge . Why Qatar not have another arrangement their Business Class clients in Montreal. The Air France KLM Lounger is better, the Air Canada Lounge is better. Qatar should send somebody to take a look ! Joseph Chung

Online check-in doesn't work. That's why I couldn't give it full Star.

The crew was great and the food and liquor offerings were good. Seats were a bit cramped. Flight arrived early at destination. That's a plus.

Certainly! Here’s a more concise and refined version of your report, maintaining a polished and professional tone: --- Crew Check-In – Kolkata (CCU) The crew handling check-in in Kolkata was outstanding—efficient, courteous, and highly organized. Flight Segment – CCU to Abu Dhabi (AUH) A standard flight overall. Notably, only one in-flight meal option—a vegetarian curry—was available, which seemed unsuitable for a red-eye journey. The crew offered no alternatives, which was unexpected. Flight Segment – Abu Dhabi to Rome (AUH-FCO) Comfort improved on this leg, but service quality was average, falling short of Etihad’s premium standards. Crew attention was heavily absorbed by a difficult couple in Row 15 (port side), resulting in disproportionate focus. It was concerning that a steward had to personally return to apologize, a task better suited for supervisory staff. This highlights a development opportunity for supervisors Anna and Quashim in managing guest escalation professionally.

Flight was delayed due to slow boarding process by etihad. Update food options and movies as well.

Used to Etihad employees are very rude and unprofessional but now better than before over all is okay now

Boarding was efficient, had to check in cabin luggage. Seats were narrow, food was more in quantity, received cabin luggage on the luggage belt which was fine.

I did not have a good experience in both flights of Etihad. First of all, when I was booking the flight, there were two options. The first option was a cheaper flight with longer layover (9 hrs), or a more expensive flight with shorter layover (2 hrs). I booked the expensive flight with shorter layover because I wanted a more comfortable trip. A few days before the trip, Etihad informed me that the departure time of my first flight will change 7 hours earlier, leading to an 9 hour layover, without giving me another option nor reimbursing me for the extra cost. They didn’t even send me an apologetic email for this change. Regarding the flight experience, I would rate it as mediocre. This is mostly because the pilots of both flights did their best to give us the worst approach to airports that I have ever experienced. In the case of the first flight they had to aboard the landing and took off again right before touching the landing strip. The captain said that it was due to wind conditions but the second time the pilot followed the same direction as the first time to land the plane.

Liked leg room Disliked unable to book to sit with my family on same flight without paying extra

Long way to improve. Toilets not working. Bad handling when flight was canceled

The business class experience is fantastic. The crew were polite but often unavailable even when I tried to call them! I even found myself bringing my used dishes and cutlery up to the crew because no one had come to collect it after over an hour.

Online was good boarding also but a child was crying all the way with no intervention from crew member.

1st of all on February 27th Abu Dhabi to Delhi flight the seat wasn't comfortable at all, coming back the Lounge at Abu Dhabi didn't have anything. Than the Food in the flight

The flight attendants were great! The seating for business class is better on other airlines. The food was also good!

Great food, great entertainment and very helpful, caring & attentive staff.

Very nice and friendly crew. Boarding system can be improved.

Food is getting worse. They use to be different than other airlines. Their economy classes food sucks. Stuff was very helpful.

Boarding was chaotic. Cabin noisy. Temperature a bit cool. Bathrooms not cleaned enough.

they have cancell the flight with no reasons, My parents were in the cold weather in the airport for 24 hours they did not give any hotel and food. I hate Turkish Airline, this is our last time that we ha ve chosen Turkish Airline.

Good overall flight. Excellent crew. Food options could be improved.

Flight was delayed then we had to redirect for medical emergency during which time we had no information on what is the plan. The connecting flight was also delayed.

Horrible, they forgot our luggage, the food was terrible, the crew were rude, the flight was delayed, I hated every aspect of this flight

The ac did not work and the plane was deployed for the AC BUT IT NEVER WORKED. I have high blood pressure and I was SWEATING AND NEARLY PASSED OUT. Do better.
