a longer gap btw the supper and breakfast would have been better - felt like the sleep was way too fragmented on this red eye flight

I loved the full Taylor Swift selection but felt that the other selections were limited, didn’t span the popular music eras nor a wide enough range of music genres. BUT the seat and bed were GREAT (it was wide, long enough, had great storage, firm enough to uphold body postural comfort). Outstanding crew and really great food - gourmet innovative dim sum breakfast so different from the boring standard fare offered by many other business class products.

The consistency with Singapore Airlines is fantastic. Crew are always brilliant and food delicious in business class

The business class seats were very uncomfortable. When in lie flat position my legs were very restricted.

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.

It was very good experience on board to Sydney with SQ.

Fantastic patience when one of the passengers behind me was an absolute horrible, horrible person and the girls just kept smiling and doing their job with patience and kindness. Well, done to the crew.

Once again the meal served was delicious - we got chicken rice

Very slow check in. Food poor and some of the special meals offered were not available. Luggage then didnt arrive and still waiting for news 48 hours later

55 min transit, not sure how they planned to make it work

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.

Need to improve on punctuality. My flight was delayed by 1 hour.

Seats were uncomfortable and the vegetarian meal was awful. Some of the entertainment didn't work.

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.

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.

My case was missing a wheel on arrival Heathrow and the staff were unhelpful when i tried to get some compensation stating it was not sufficient damage, i only wish that they at some point have to deal with the same situation it put me in, maybe they would change their attitude but overall it was a good flight

We are satisfied with the cabin crew serviceand the quality of meals served.

The aircraft was really old, the staff demotivated and the overall United airline service is horrible

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

Excellent service. departed on time, and arrived ahead of schedule. The whole restrictions around no food/drink is a bit weird even with Covid. Also, no mobiles and iPad use during takeoff and landing is very 2006!

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

The flight isn’t great, as the plane has faulty with light and noise. It blinks and make noise for 8hrs non stop! Causing health and sensory issues! Causing Hazard matter to all 3 babies that on bassinet seats. This matters affected 12 passengers and the most horrible flight I ever experience. Have been flying with MAS for more 30yrs and this is the worst! Very disappointed

Service / food has to be much better. Staff were not very attentive to requests. Requested for a second serve of coke and got a weird look back from the host! Was also told they don’t have extra water bottles when I requested for one before sleep! Dinner time food was very minimum and average.

chaos boarding. Crew in business class seemed short staffed and lacking in attention to details initially, but did improve during flight.

Delayed, not enough information. Had to ask for refreshments, crew could have been more proactive

My first course flight (Aor-Kul) was cancelled in the morning, and they asked me to board the night flight hence I need to transit overnight for the 2nd flight (Kul-Myy) that supposed to be on the same day. The overnight stay was not provided, (I'm traveling with my spouse, a daughter (5 y.o.) and an infant (2 months old). Hence I booked Sama Sama Hotel at my own expense (fortunately using my enrich miles points). Other than this issue, all services is good.

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

I had purchased extra leg room for all legs of the flight but due to a delay in leaving Perth I was put on another flight but with Emirates. My luggage was initially lost but later found and my suitcase was broken. I ended up losing my upgrades

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

I appreciated a meal on the shorter flight. It was slightly delayed with no announcement but I was able to determine what was happening.

Really old air craft, broken seats and tray tables. Entertainment screens don’t work. Charging ports didn’t work.

seats were not comfortable, entertainment was not working and food could be much better, given the airline calls itself full service and india's flag carrier.

Terrible airline... Originally, the flight was canceled and didn't receive a notification, had to learn from their twitter account... Rebooking was a huge pain... Every other airline like American and United did eventually fly a day later... The flight had a layover, no other airline needed one... India is such a weak nation globally, this airline has no leverage to negotiate good airspace... Flight left late, again no notifications as to why at the airport. On the plane, wifi is spotty, chargers don't work... The only saving grace used to be good food. Even that has gone down the drain. Just the worst!

The flight was on time, the entire experience was very smooth. The Flight crew were incredibly professional and nice. Made us feel very comfortable

Flight has no entertainment. Crew doesn't care atall. Horrible service and never going to take Air india and will spread their Horrible service.

Very bad experience luggage never made to destination no help form airlines staff aircraft was old crappy forts staff service bad airlines staff

The boarding experience was very organized and easy to follow. The flight was pleasant and the food provided was also very good. Both Delhi and Mumbai airport have metro connections which make getting around much easier.

Undisputed leader in sky for Indians. Very good crew right from ground to mid sky. Very sumptuous meals twice

Ok, where do I start, hmm! Good things first - the meals/food was tasty, the seats are comfortable and legroom in Economy was ample and foot rest with message roller is simply amazing, Wi-Fi Entertainment works well. Bad things - in-flight entertainment screens and remotes either had physical damage and or simply not working. This was the case for more than 1/2 the flight. Flight that was long haul - 12+hrs non-stop. If you want a cracker or a biscuit with your tea - forget it, they carry none. Feel like having a chilled beer - forget it as they will serve you room temperature always and every time. The crew seem young and inexperienced. Will I fly again, yes I would only because it gets me from Sydney to Delhi in 12.5 odd hours (fastest), otherwise I will never. It has been what a year or so since TATA took over but I have not seen any change, I really hope this changes.
