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.

The flight gate was changed and all the pessengers were waiting at the gate #2 for boarding, There were 4 (four) employees standing at the boarding desk and no one ever said anything about the gate changed. Finaly when I noticed an employee was removing the boarding zone signs, it surprised me something is not right, so I went and ask that employee what happned - she said the gate has been changed. So, i questioned again which gate it would be, she told me gate #5. I look for Gate 5 - which was down stairs. When I went to gate 5 - no body was at that gate which depress me a lot because it was already a bording time pass. Later I checked on the departure screen for my flight - it was gate #1, so I had to go back again upstairs in hurry as the boarding time already pass. They never anounced or telling customer anything at the original boarding gate - WHICH WAS TOTALY STUPID. I am 77 yrs old and what they the employees and the managers care about) care about how I can handle all this going back and forth. Air India is just advertising they are getting bigger but their services are just BOGUS and I don't expect it would be any better. They are getting worst and worst than they use to be.

It was just like any other budget airline in India—nothing extraordinary. The check-in at CCU was surprisingly smooth and effortless, as expected after online check-in. But BOM? They had me join the regular check-in queue, while six Bag-Drop counters were busy doing the same thing. Makes you wonder how Vistara plans to promote web check-in if passengers end up in line anyway.

Flight was delayed more than 18 hours, checked in bag damaged, no accountability from vistara ground staff. Worst experience. Shall compensate all the charges with double Ticket refund

The flight was an hour late. There were no gate announcements or displays. After getting on the plane, there was a further delay without any explanation.

The flight was on time. I upgraded to Premium Economy and it was comfortable. The food was very good. Staff were courteous.

Flight was delayed but no announcements were made. Till the boarding it was still showing original schedule time at the monitor and also on your mobile app. It left the gate half hour later than scheduled.

It’s really very nice experience with very nice behaviour respected crews n all Vistara members thankyou so much Vistara to give us humble hospitality

My wife with 5 month son were traveling. No proper support was provided for luggage handling. Although it was requested in prior. My wife sole manage everything and was not as expected.

This was an old 320 without a screen or USB charging port even in the business class. The food could have been better.

a real good flying experince. Everything was excellent right from check-in to baggage collection at destination.

Terrible experience at IST airport due to mismanagement by ground and wheelchair staff.

Some seats don’t recline. No USB port or power outlet, no inflight WIFI - not even for SMS/Messaging apps. Ontime performance was very good. They should have at least one crew member who speaks the local language, for flights like these.

Some seats don’t recline. No USB port or power outlet, no inflight WIFI - not even for SMS/Messaging apps. Ontime performance was very good.

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.

Not professional and didn’t know about double seat even when I paid for it and have a confirmation. Lack of comms between teams.

deboarding is very poor after landing it took around 45 minutes to come out.

My baggage bag got broken and only 3000 voucher was given for compensation

Crew members forgot to serve sandwiches after serving the coffee. Worst was the handling of bag. One of wheel was Broken making it useless. Though a complaint was registered and assured of compensation voucher equal to part cost of the new bag.

The seats are horrible and pathetic. The flight was delayed by over an hour as they did not have the crew

Please don’t send survey questions on Indigo flights. 90% of booking, check in, Boarding work is done by the passenger. So those questions are irrelevant

very run down aircraft. seat tilted. the mobile / magazine holder was broken. The entertainment screen was not working. The crew was good, polite and helpful

Food is good, staff is good... Wi-fi quality is poor, disembarkment after landing is atrocious.

Flight crew was lovely. Bathrooms should have been cleaner. The handsets in business class for watching the entertainment are horrible. Very difficult to figure out which buttons are for what. I managed to get the flight maps on my screen but it wasn't easy. Never got anything else up.

Inflight Services are poor compared to other airlines. They do not offer even water during 15 hr flight. Food is little in portion and I had food poisoning after last meal ( rajma chawal)

This was a bery good experience as it was a newer plane . AI older plane bussiness class is bad .

I had a camera bag that exceeded the 10kg allowance for hand luggage. I am 67 years old and have been travelling will my cameras and lenses all over the world and have not paid once for the excess weight. Also, even if I wanted to check in the bag, I can’t due to lithium batteries and delicate equipment. Air India should review their policies. Or is it just a cash grab. I had to pay additional 7000 rupees.

Other than the inflight video screen freezing for about four hours everything else was brilliant.

The aircraft interiors are falling apart. Felt like a waste paying for business class as it was indistinguishable from economy in any way.

What a pathetic plane it was. Entertainment system didn’t work. USB port was broken. There was a hole on top of folding serving table. Broken restrooms in the middle of flight.

Our seat monitor did not Not work either way going to Vietnam. I had a bulkhead seat with plenty of room, but with No monitor, it was a long flight with no movies. Fun was good, staff was Excellent.

The flight didn't even take off and cancelled in a royal manner. Hopeless airlines.

The flight got multiple changes of timings and ultimately I had to cancel it.

I have been an NRI living abroad for the last 35 years, but I had one of my worst experiences recently at the Dharbhanga airport, especially with the ground staff. Their behavior was very rude; one of the staff members almost abused me and charged me extra for my laptop and cable that I was carrying from Dharbhanga to Delhi, where I had an international flight. Despite being careful with the weight limits, the ground staff treated me very poorly, making it one of the worst flying experiences of my life.

Staff could have been helpful when traveling with kids and seniors. Not at all professional staff, just some janitors who do not understand hospitality. The food was horrible; the tomatoes tasted foul. The flight was small and the legroom was not good.

Flight was changed without proper monitor display. Boarding process was confusing with no announcements.

Flight arrived on time even though boarding and takeoff were delayed. No infant seatbelt provided. Crew was a bit indifferent. Baggage was damaged and representatives refused to write up a damage report.

IGI T-1 terminal is under renovation. So, the boarding and check in process took extremely long, due to reduced number of kiosks. Further, the flight was delayed by 1 hour 15 mins. The same was not being properly informed to the passengers because of which a feeling of slight chaos was evident amongst the passengers. All this further increased the discomfort, which was already in the menu due to the ATR aircraft. Lastly, the Spicescreen website wasn't working properly due to pathetic interface and poor wifi connectivity, which otherwise could have been a pass-time during the flight. Such issues were not expected from Spicejet and need to be taken care and handled in a better manner in future.

The flight 3 time delay I was so nervous and full tired

Flight cancelled without notice at the 11th hour, refund not done now one week passed

Timing Should be Accurate to Fly Flight was Delay By 3 hrs
