The seat in front of me seemed to have extra reclining, which made my seat tighter. I couldn’t see my movie properly when the other passenger was reclined. Food was OK, but there was a long period without food, considering it was a day time long flight.

The seat in front of me seemed to have extra reclining, which made my seat tighter. I couldn’t see my movie properly when the other passenger was reclined. Food was OK, but there was a long period without food, considering it was a day time long flight.

Our flight delayed, due to the incoming flight arriving late from Paris. AF caused us to miss our connecting flight, also booked through Air France directly. They couldn't accommodate us until later that night, and we had to be in AMS earlier than that. They won't do anything else to help us and wanted to charge us more money to rebook us too. Not great service, since it was all their fault.

The check-in at the airport was smooth and helpful. There was a delay due to some issue. The good regular but the staff very attentive.

Air France removed our luggage from the plane before it took off, seemingly intentionally, didn't notify us until after we reported it missing at SFO, and is giving us no updates on when, or whether, they will deliver it.

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

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

The male attended that served are section was a snob. He did not answer my call light when my wine spilled all over the floor. I did not push it again or drew his attention to it. He just ignored the call light when he came to give us our meal, serving the people behind us first. I did not push it again or drew his attention to it to see his reaction. It was so obvious that he was ignoring us. We were in premium economy!

There was 2 hours delay before boarding and 2 hours delay after boarding while waiting in the plane

My seat was so uncomfortable, and the headrest was broken. Very very disappointing for the price I paid.

The hard product, food, and service are far superior to their North American counterparts
