JAL is an exceptional airline that shows the true heart of Japanese omotenashi service. If the option is available I’ll always chose it

highly recommend for trip to japan only reason why i gave good not excellent is because their selection of movies and tv shows in English is more limited .

I avoid American Airlines for a reason. Our flight was delayed at LAX. The situation at the gate was chaotic. The woman making announcements wasn't being clear or transparent regarding why there were delays. There was a lot of confusion regarding flight and gate status. Other passengers were pretty rude. I was elbowed in the eye by someone who was in a hurry to get their bags from the overhead bin immediately after the flight landed. Ultimately, I will avoid AA as much as possible in the future.

Issue 1: We had a 2 hour delay to repair a windshield wiper, during which we sat on board on the runway. Issue 2: it was VERY HOT in the cabin for most of the flight, we were sweating. We asked to make it cooler. They didn’t succeed in doing so. Other than that, it was great. Fantastic food, and extremely pleasant, accommodating flight crew.

My total experience was good. The food and entertainment need improvement.

We booked business class round trip from Delhi to San Diego and back. On our last leg from Bangalore to Delhi we were down graded to economy class which was big disappointment other than that everything was great.

I would like to add American food so tired of rice after being there for 10 days didn’t want anymore to pay an airline did not have my bag marked right so it is still sitting in O’Hare. I am home.

Impeccable services, excellent meals, on-time flights, what more can you ask for!

The entree wasn’t very good. The rice was soggy. The side dishes were all good though. The breakfast was also good. The crew were excellent, as usual.

Website from the 1990s, super frustrating customer support, inflight experience merely OK - more like United than e.g. Emirates

It was okay. The airplane was a little smaller than a flight from Thailand to Helsinki.

Wish that everyone would board the back of the plane first. Also let kids on first. The gate wasn’t open at arrival and we waited 45 minutes to takeoff. They made up for time in the air.

This was an absolutely exceptional flight. The flight attendants were extremely attentive and very friendly. They seemed to go out of their way to make us comfortable and to make sure that we had everything we needed., We were in business and were very happy with the size and the details for our pods. We would definitely recommend Finnair and will definitely be flying with them again.

We had an excellent trip with Finnair. This was our first time and we’re very pleased. The only issue was with the boarding - it was a little bit confusing and needs a little bit of streamlining.

Crew very lovely. Arrived an hour late due to bad weather. We were given new tickets to an other flight but it could have been organised better, so we did not have to run through the whole airport to.

Flight delayed over an hour. They said they would hold our connection but then did not.

Major problems checking in at Alaska counter. They could not find our booking code because it came from Finnair.

Do not use KAYAK or Finair for future travel. Unless you purchase the tickets directly from the airline, you were going to have a difficult time checking in. Kayak canceled my flights twice and ended up causing great difficulty in me getting back from Europe because they double sold my tickets between American Airlines and Finair. The event caused significant delays and led to me having to rebook my flights.

The staff were all particularly great. The plane was clean and fresh. The bassinet worked great. It was all very nice.

Boarding uncomfortable. Stewardess said I would have to check my carry on as there was no room in the overhead bins. Another passenger helped me find a spot.

Business class points redemption - good value for points paid, dubious value if out of your own pocket, domestic class business product okay for this length of flight. The flight left and arrived on time, crew were good, aircraft was a bit old and tired, but still miles ahead of their competitors in Virgin and Jetstar.

Airline running better than post Covid, proper boarding process now implemented, some aircraft feeling a bit old and tired, crew fine, online experience better.

We were upgraded and after just a short delay in attending to a safety check we were on our way. Would definately fly Qantas International on their Dreamliner again.

Five hour flight instead of four hours due to westerly headwinds which wasn’t the fault of Qantas !

I tried to check in online but was unable to do so. I stood in line for nearly two hours to check in. American Airlines was understaffed. When I finally got to the kiosk to check in, I was still unable to check in. No AA staff was available to help. Finally one of the airport security agents who was helping passengers became of lack of AA Staff told me: “I think the reason you can’t check in is that you are starting your name with an upper case letter when you write it. Just write it with all lower case letters.” That did allow me to check in. HOW COULD ANYONE POSSIBLY KNOW THAT IF THEY USE AN INITIAL UPPER CASE LETTER TO SPELL THEIR OWN NAME, AA WOULD NOT ALLOW THEM TO CHECK IN?????? Then I had to wait in line over half an hour again to drop off my baggage. Although I arrived at the airport 3 hours early, by the time I got to the gate, they had already started boarding.

One of the oldest most uncomfortable "lay down" seats I've ever experienced. Old plane and old seats that don't lay flat. The seat back does not even recline - at all. Instead the legrest awkwardly extends to fill the gap between a small cubby into which you must insert your feet/legs. I am 5' 11" and could not lay straight but had to tuck my knees. Ticket was also very expensive. Would not recommend flying business/first on Finair from Melbourne to Bangkok and will not do so again myself.

The wifi was out. Otherwise it was great flight. Richard, as CSM, was excellent.

Traditional economy class. Not a full flight so spare seats. Food and drinks were good

Was bumped to a later flight because of inefficiency on part of the airline.

Inflight entertainment, poor that there are no headrest screens on aircraft used for an international flight.

It was OK as the seat which we paid for doesn’t have any window. We paid $120 for 3 seats but it’s for nothing. Crew could not help. None of the ports worked so all our phones went dry

A380 First Class Apartments were phenomenal. Comfortable bed and matress cover, superior vegetarian five course meal, shower, small business lounge and plenty of exercise walking around the aircraft.

second leg was more comfortable. Customer service in Abu Dhabi is okay.

Horrible. After paying for seats, I was cramped, my daughters legs kept hitting the seat in front, I had no overhead bin space and no help from stewards on board, the food was served cold, when asked for snacks was told to wait and never received any, the flight was cold with no temperature controls. Entertainment was outdated. I booked this through partnership with American Airlines but will avoid in the future.

The staff were wonderful but the seats weren't very comfortable for a bigger guy like me.

This flight was a dreamliner so I think the space was ok for the legs, but the option for food was again limited and the crew was same.

Bad. Flight was very uncomfortable with narrow and shallow seats, very little food and water. I will not fly etihad again.

Boarding catastrophic let alone have to claimb the plain rather than using jetway. 5.5 hr delay leaving had to do stop in Lgw for a new crew which further compounded the delay. Connecting flight would not wait and had to pend a night in a hotel. Curiously my seat would not go full flat.

In never flown this flight, because my flight coning from Barcelona was delayed.

The flight was delayed which cause me to miss my connecting flight in AbuDhsbi airport.

The best airline food being served for business travellers. Excellent food.

The economy seat was so uncomfortable, had not enough leg room for 13 hours flight, front seat basket was broken and couldn’t hold anything, food quality was horrible( we got food poisoned ) we charged for logged which used to be free. We paid too much for this flight and very disappointed. Turkish air line better to make satisfy and respect people instead of find different way to scam people.

Overall great airline that still provides two suitcases, has a huge hub and crew goes above and beyond to assist you. Boarding took a lot of time as there were only 2 people checking in. Also, in Istanbul, taxing took almost 30 min.

The food we received during the flight was excellent. The service was very friendly. Definitely the best value for the money when flying across the Atlantic.

Except for spending an extra day in Istanbul due to late departure from Athens on Saturday and missing the connection flight TK0044 to Cape Town and again arriving 45 min late on Monday in Cape Town, it was all good.

The 2 agents on the check in counter were super nice , helpful and very polite. Boarding was like a 1 2 3, I would recommend Turkish airlines for your next trip.

flight with heavy turbulence old boeing 777 rest wasnt clean dashboard doesn’t work

for the second time disappointed with TK, they like JAT = joke about time

No customer service. Non educated staff members with no will to support or service the passenger.

Aircraft you use on this route are always old and poor! This drives the entire experience down
