I would have liked less packaged snacky stuff, more fruit. The crew was great.

I would have liked less packaged snacky stuff, more fruit. The crew was great.

Warm staff, very responsive service. Well furnished cabin and comfortable seat and amenities. Excellent onboard wifi connection and very large comfortable restrooms.

It was delayed for 2 hrs. Flight attendants were not attentive.

We boarded but due to a technical issue we spent 4.5hrs on the ground waiting for the issue to be resolved

Wonderful Premium Economy experience. Felt as good as Business Class for food and entertainment. Comfortable sleeping too

Crew were excellent and the bar service and chat fantastic. Cheese board delicious. Amenity kit good, very disappointing not getting pyjamas on this leg of the flight and needed to reuse from earlier flight.

No kids provided. Instead we were told to have contacted the airline that we have kids and require kids meals. We were not the only ones who inquired about kids meals. It’s odd. Emirates and other airlines give kids meals as standard and before the adult food comes out. The rice in our meals was gluggy and under cooked. The chicken was also raw. Sadly not the best experience with Finn Air. The hostesses tried to compensate with the snacks and drinks but missed the mark by a long way. Especially when paying Emirates/Qantas prices

the seat is quite narrow compared to others. entertainment and food were very good

Hospitality is good. Should improve on buggage handling because l lost a suitcase. Layover in Dubai was too long , 6 hours

Similar to Hyd->Dubai this too was worst airlines. Bad seats, bad seating arrangement which created lot of confusion since family member were not given seat together. However most of them changed the seat and got with the family. Cheap tactics by Emirates.

I find it was a bit hot before take off. If there is a way to improve the airflow it would be great

Excellent service. I pre-ordered gluten intolerant meal and they handle it with care. They served me my meal before other people's to avoid crossed contamination. Thank you 🙏

The crew was very courteous and professional. the flight is relatively clean and comfortable.

a completely full flight - felt quite carmped in, despite being on the window seat. Meal served could better. Surely different from pre-covid trips I used to take to and from Bangkok.

Wish the seat don’t have restrictions, can’t fully insert backpack all the way inside.

Lounge a access was excellent as was the attentiveness and service from the crew as always. The food and drink supplied were of good quality. The entertainment system had a good selection and I liked the mapping system supplied. However the screen wild have been bigger and the operation a little smoother to navigate. The seats were barely comfortable, but adequate.

The staff on the plane were attentive and friendly. The frustration with the cabin crew was that we were served second to special diet people. And, we were in economy section. The boarding staff was mediocre. Got scolded for requesting to sit with spouse on 14 hours long flight home. Was told they cannot break up families for us. Didn’t understand how we were denied sitting together as we are husband and wife. After many words of exchange, we were accommodated. Cleaning crew did a horrible job! Bathrooms were unsanitary or dirty from beginning of flight! Didn’t expect sparkling as its economy, but did except decent.

Headwind delayed our flight which wasn’t the airlines fault

We were not given option for meals since they ran out of the other option but good thing the remaining options tasted great.

Both the staff at check-in counter and on board were pleasant and helpful. My chicken and mashed potato was good, sauce was tasty, but the zucchini, carrot n other accompanying vegetables were over-cooked a little. (I understand the meal has to be prepared earlier). Yet I would fly on Singapore Airlines again and recommend it to family and friends.

I didn't have much experience with Cathay Pacific airlines because of delay and missed connections, the bulk of the trip was on Japan Airlines.

Few vegetarian food options. Incorporating one per meal service would be best and captures a wider audience than just vegetarians (individuals with religious meat restrictions can also eat vegetarian).

Cramped, hot and the plane was grubby. Also the plane was an hour late and it took an hour to get my luggage once I got to LAX.

Flight from Hong Kong to LAX was late, the plane was grubby, overcrowded and hot. I recently flew Starlux and that was a MUCH better experience.

The bed was alright in business class. Food variety and quality were not up to the mark compared to the business class airfare.

Given the Business class airfare, the food variety and quality both were substandard. The crew was not interested to serve other choices and work hard to provide alternatives. Very disappointing food service.

Crew and food were great in-flight. We had a 2 hour delay, no communication, and just got left in a limbo. The crew arrived late and they were running checkouts on the plane (which is important, but why not doing it earlier?) Cathay did nothing to about the delay, and a lot of people missed their connection flights. I had to run and got stuck at checkpoint, which made my entire trip very unpleasant. Got to my gate 5 mins prior to them closing it.

The experience was efficient, on time, and provided great service.

My flight was suppose to be at 7:45pm to fly but it didnt fly out until 8:55 to dallas so then all of my other flights was late and delay ihad to wait at the airport for extra 14 hours to be able to get on a different plane

Flew from lax economy on cathay 777. Seat configuration 3-4-3. When the forward seat reclines it feels like someone is leaning forward and staring you. If you are slightly big tray tables will touch your abdomen even with seats upright. AVOID this above 777 configuration at all cost for a long flight. However their Airbus 350 3-3-3 configuration felt spacious and Seats wider.

It was mediocre. Honestly, the flight was late but that didn’t bother me as I had plenty of time. The only thing that bothered me is that the crew never asked to make the beds for us in business class. Maybe the crew was exhausted and that just didn’t occur to them.

Nice crew , clean cabin , food was delayed due to problem with the quantity .

On this flight...fine. The one from India to Abu Dahbi, awful.

We have paid premium price for a business class Cabinet and we have received the old 777 with the following apart business class that is not to standard. It was very disappointing and it’s a very bad reputation for a premium airline company. This aeroplane should be the commission from being as a business class. We will pass this knowledge to our colleagues because the quality of business class in Etihad is not consistent and it is a lucky dip that sometimes you’re getting a good aeroplane and sometimes you’re getting their 30 years old aeroplane. The crew of the aeroplane have apologise and said that they hate this aeroplane and they have complained about it multiple times as well. Obviously Etihad is putting the economy in front of the Customer Experience. For the future we will not take this risk anymore and will fly with established company like emirates.

There was not any issues with the Etihad Airways. Staff was excellent and I love the variety of movies and games that they provided.

It was fantastic. The flight from Chicago to Abu Dahbi was fantastic. The crew, food and service were amazing. Everything was handled by the crew member assigned to us , Nicholas, was usually done before we asked for it. Highly recommend Etihad!

Etihad Check In counter/Station manager in Heathrow was bothering and not helpful at all. They are rude and not customer oriented

My baggage was not boarded and is still missing. I was only carring one piece of luggage and that is misplaced now I am stuck at mumbai without luggage. I had an onward journey from here

The WiFi was not compatible on both my phones (Vivo Y30 5g and Samsung Galaxy A32) with up-to-date android software.

Old plane, old entertainment system. It wasn't working throughout the entire flight. I was offered to connect to their system via Wifi to watch on my phone. Crew wasn't very helpful except one lady who turned the experience around.

Aircraft was comfortable even in economy, clean. Entertainment screens were excellent and. Hoice was very good. Good was just ok. Crew was not bad.

Entertainment system didn't work well. Also no new movies and limited choice of other programmes. . And only one USB A charger option. Most modern electronic items needs USB C. Planes should offer both

I was unable to board the flight because I was unable to acquire a visa , Brexit changed my ability to get an ETA, I’m a Trinidad citizen and it takes weeks to get a visa

The issue was not with BA it was with the link yoiu sent fopr booking the flight

The space in the seat was okay, the staff were friendly, the entertainment system, my touch screen was not working and some of the films listed on the website for the flight were not available.

BA flight from London NY had old BC configuration with 2+3+2 seating with open seats which was not comfortable and lacked privacy

Flew business- but plane was dirty, food horrendous. Too many business class seats diluted service levels overall.

Loved the boarding option from Business class lounge, experience on flight was excellent, plenty of good food choices

I don’t think you’ll like the shoulder require people to pay to reserve seats. Also for the people in the bulkhead row the luggage locker nearest to their seats should be vacant. Both sides were filled with crew or airport items.

Experience was bad. In business class, they ran out of food choices. Luggage was delayed by 2 days in both to and fro flights, ground staff was not helpful, took 3 hours to log the complaint for missing luggage.
