Middle seats SUCK!!!! I paid more money than I should have because of your terrible site Kayak.com. I'll try to use your competitors going forward. I am so disappointed you would play off business class.com as business class seats

The boarding was efficient. The entertainment system was a bit unstable but Air France has a good selection of movies.

They lost my bag and I still haven’t received it yet

They lost my bag and I still have not received it

Not consistent with the food quality (I mean taste not freshness)

Food was really mediocre for premium economy in comparison to other airlines… the crew was nowhere to be found… 14 hour flight…

Worst airlines either. First leg was delayed because of crew not available. My connection was missed so they booked me automatically the next day! But, impossible to get anyone on site, web site does not let me access my reservation anymore, confirmed by useless agents over the phone. My 2-leg trip with part in business class arriving at 4:10pm ends up in an awful 3-leg arriving at 9pm the next day with no way to even choose the seats and of course at the very end of the plane. I can understand problems arrive but the way Air France handle it is just unacceptable. You are on your own. Apparently getting you to your destination is the only thing they consider their duty. The customer experience and fatigue is none of their concern. And I have a status with them. I will reconsider my priorities when flying with Air France and encourage everyone to do the same.

Our flight crew were terrific. And they handle a difficult passenger with finesse.

Excellent, Lima to Paris. But Paris to Amsterdam, delayed, missed my flight and KLM treated its missed flights passengers very badly, terribly bad. No hotel accommodation given. Passengers were told to find their own hotel accommodation and claim at reasonable rate and left the booth and literally with armed Police Officers listening to passengers complains. For three hours, after moving by Uber from hotel to hotel and calling and booking online, no hotel was available. I had to return to the airport and seat/sleep on the benches, suffering the cold, and rats running around until my new allocated flight the next day. It was the most terrible KLM treatment even seen and being a Business Class passenger. Still mentally suffering to date as a result.

3 hour delay but out of their control. App said I get vouchers but when I applied for them, they were nowhere to be found in my account

Awful the whole airline arrived to check baggage and board our flight and the airline desk was closed where none of the passengers could check in baggage, asked for a supervisor and was refused a supervisor, called the airlines from the airport and they refused to refund the flights for their actions in the airport, Etihad and Garuda Airlines absolutely horrible customer service all the way around.

Dirty and smelly lavatory and toilets in Wamos Air operated flights

The crew could have been more friendly and could have offered to make the beds. Also, Ethiad should have more vegetarian food options.

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.

I booked and paid for a Business Class seat for myself and my wife. 4 hours before the flight i get a call saying the plane they sent doesn't have the correct layout to accommodate all the business class seats they sold me 3 months earlier at a premium of $1500 a ticket. So they have to bump me from Business to Economy and will give me a $400 credit (total of $800 for both seats) that I could turn in at Abu Dahbi for $400 in US cash. They then promised a row that we could have to ourselves and the arm rests would go up so we could spread out for each of us. My wife was taken care of but I was put in the exit row with the flight attendents set as part of the three...and the arm rest did not go up. When we got to Abu Dahbi, they would not exchange our credit for cash as promised. Very disappointed they took my money 3 months ago and refused to reimburse for the change in seats or follow the promises made.

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 an old plane with seats not comfortable and with little space for the legs. I must say that the previous flight I had was amazing on a very comfortable new plane

Seat space was tight and uncomfortable. There was hardly any cushioning giving me a terrible tail bone ache. Getting and out was extremely cramped. We paid for seat choices and felt totally ripped off. Food was mediocre. By the time the servers served 2 or 3 rows they ran out of this or that option as we saw on the inbound trip also. This is infuriating. Entertainment choices were extremely limited for such a long haul. The screen froze on occasion and did not switch off when the on off button was pressed. When it did it came back on its own in 5 seconds. The airlines has gone downhill since last year.
