Great flight - Clubhouse met our needs, and the staff provided good service. Boarding felt a little chaotic, but given the size of the aircraft, it's always going to be challenging. Whilst the crew were friendly, the number of passengers meant that we received our breakfast items, but had finished breakfast before we were served a drink. Lunch was much better organised, and throughout the flight, the crew were attentive. Found the seats and ICE to be excellent. Disembarkation was fine, and everything possible to expedite the process was being done.

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

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

Can’t complain Only downside was the Kiosk passport check and customs clearance at Melbourne. When will they improve that service🤔

The staff on board were excellent. Kind, thoughtful, helpful - not just with me but with others around that I observed. Wonderful service.

Very pleasant.The crews are very helpful.Food are very good.

First time and very memorable, the finest flying experience ive ever had

Boarding for business class passengers can be improved. Also, when debarking the aircraft, Economy passengers are let off first due the way the configuration of the cabin upstairs.

Overall I was quite pleased with the experience; the cleanliness; the polite and attentiveness of the cabin crew; and the delicious food options.

Very efficient and professional staff. Food was good and so was entertainment selection.

Crew and food was good, ok leg room if you don’t have a big box under the seat. And the seats are so narrow (I’m only 70kg), will consider an alternate airline next time

Boarding from DOH to SYD the Business Class were pointed in a separate gate but no one there to receive us. Otherwise it was ok.

The flight was delayed and one member of the crew was a bit rude. But apart from that all good.

I wish the leg room was better for Economy especially for the outbound flights to India . The outbound flight to US and Qatar was good

The check-in and crew staff were wonderful. The food was reasonable. The online side Qatar was very poor. Seats were very tight and not very comfortable for a 14 hour flight!

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.

They didn't board by zones and it was a free for all. The 16 hour flight was the most excruciating experience of my life and the seats were TINY... with no leg space and my feet were swollen immediately. The food was so bad it was inedible.

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

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.

excellent, the staff was kind and the boarding process was with no issues or hassle

Wish the flight attendants were more attentive in serving food

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

I was charged $604 for a bag that weighed 17 kg. I was given three different prices until they landed on the most expensive one and didn't budge a penny. It's ironic and a bit enraging because the total cost of my ticket was $468. I've traveled the world and never experienced these kind of prices for only one piece of checked luggage.

One of your male flight attendant was pushy and a bit of a martinette. Completely unnecessary.

In Colombo when I-drop my baggage Sri Lanka air line crew not polite way talk very rude

Same problem place in the middle so small Im 1,85 m so not good 👍

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

Did not provided with option for class upgrade. Staff at gate was not able and willing to accommodate with class upgrade, eather with plenty empty spots in business and first class.

Surprised at the lower quality of seats on the Boeing 777 in Business Class. Seats are tight and the whole Business class section is jam packed with seats. It doesn’t feel like Business Class at all. Also the way the tray tables are placed with a huge bulky solid metal hinge at knee level makes it so uncomfortable and always anxious that one will accidentally bang their knee on it. Quality of amenities has also declined. Over priced tickets with diminished quality of the entire experience.
