The only reason the overall rating wasn't "excellent" was due to problems in claiming luggage. The bags are delivered to the main area (Cinta 35) for domestic passengers, but to a DIFFERENT ROOM for international arrivees. After waiting 30 minutes, someone (who didn't appear to be from Air France or the airport) told us to go to another area. There we found our bags, which appeared to have been awaiting us for a while. We had to go through a bag check before leaving the airport. If we had been alerted to this possibility, or better yet, been to go directly to Cinta 34, we could have eliminated quite a bit of waiting.

Much better than the major US Carriers especially in Biz Class.

I wish that the meal included a vegetable or even a salad instead of couscous! Why serve chicken with rice AND couscous? Service was good overall though a bit lacking in friendliness. Usually on air france I've been offered a glass of champagne before dinner, wine with dinner, and a digestif after dinner. We were only offered wine this time!

It was not Air France but Air Europa. But confusion over our checked luggage. Whether it was checked all the way to Tenerife or not. It was not. Had to line up again in Departures. At least our Sky Priority was honoured. Flight was fine.

My wife and I had a row to ourselves after moving seats. There were no TVs and you had to buy food. So we did nothing but had a quick nap. Flight was fine.

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!

The plane was old Only 3 bathrooms available for economy The entertainment was old and the selection was poor

Georgian Airways check in staff initially denied us, because they thought passengers required transit visas to transfer on connecting flights. This required 70 minutes for them to call multiple people to confirm how transfers worked. They did not apologize once accepting our check in. Onboard, the four hour flight gave stale bread with spam slices as lunch. The only included drinks were still or sparkling water.

I did not get my baggage at my final destination..poor coordination with connecting flights with partner airlines (Saudi airways). Also the food was very mediocre.

Not a good one this time. The absence of internet without any information/notification ahead was really the unacceptable part. Also this new A350-900 has a serious legroom challenge for economy seats. It’s more like a medium-haul flight legroom configuration.
