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.

Everything was good. The red seats were a scam. Just like any other seat but red. Although they let you board earlier which was very nice.

Other than the bus wait time to off board passenger when we reached Don Muang, everything else was excellent

Very good, it would be good if payment for drinks could be accepted by card too.

Ontime, no frills, the cabin is clean, the ticket price is lower than the full-service airlines.

Paid for a meal we didn't receive. They admitted they had forgetten ours. No compensation or rectification offered. We requested if they would just give us a glass of wine instead and we would call it even. Crew advised they could not do this and to go to Air Asia counter on arrival and request a refund. Our flight didn't arrive until 2am so this was not a viable option. The crews solution was if we wanted a wine we should purchase one. I was unhappy with that suggestion considering they had already ripped us off with our meal.

Took 4 flights in 5 days 3 out of 4 left late about one hour each.

The boarding process was very poor - refueling on so rear ladder blocked. I think while boarding both ladders should be accessible so that passengers are comfortable instead of crowding through front ladder

No WiFi or movies. And the seat We’re uncomfortable. Good thing it was a short flight

It was on time! First time in a long time for Air Asia. Thank you!

Nightmare at check in because of restrictibe and unmanageable baggage rules. Very long line and slow because of these policies. Not a smart way to make $

From the checking, ground handlimg was very poor.seems new personal on duty,people qho suppose to be teaching them didnt see around.new people may mislead passenger, as of flt info boards, not give proper info.even informatiin counter people dont get uptodate info.makin big ques, totally disaster.guests were not happy about it.even boarding to aircraft some BC class pax sent to aft staircase, some aft pasx sent to front door.poor ground handling.may need to improove.

Nice crew.flight delay fromBKK for some ground prep issue I guess, crew serve well to guest, and respect to guest as well. As usual AC is old,and nt much comert in compare to other rehional airliners.other than that.all good

All good, on time, depart.only bad side was, airxraft is too old to be in business.hope ailine will manage somethinv somewhat.all good

Flight was on time.food is as usual good.Aircraft is old.old A320, seats aithout any display.crew serve well

Was good, comparatively. A330, with good crew set.on time depature. And crew try there best, to make thing efficient.

Spesific ,Crew and cabin manager, look after all pax on board despite being in a old A320 equipment.Got free seat upgrade as well,but old style seats, no much comfert on it.But food and the spesific crew, was amazing.maintain airlanka standerd.the cabin manager, who was so much keen,keen operate as per SOP.

Was got free upgrade, on old A320.aircraft is out dated kind of.bt service ,cabin manager, tried there best.and food was excelent.

When flying from Indian Sector, should be more prepared with Indian food

KAYAK Real time status update is not accurate.the flight inbound rejected and go around.and came back and land. Delay abt 30 min.still shows ontime.track ur self if u wana real time.and cabin crew s are nicer. Aircraft is jst ok.old airplane.and in midflight ,seems have some compressor issue.airconditioning was nt work properly either.I could litarary see guests were cheking if AC is working.bt on landing it start to gv cool.which probably some one intentionaly kept .which was so bad.even breathing was bit difficult.otjer than that.for me all ok.

This leg of the trip was smoother than compared to the initial trip. Sri Lankan Airlines still have much work to do to improve the overall travel experience.
