I've had the "pleasure" of flying both economy and business class of AF. Let's just say the exterior of this 777 of theirs is reflective of their service, food and product.Would you be eager to fly on a scuzzy aircraft? It's almost as if cleanliness is a good indicator of overall condition...
Yes, many airliners have dirty aircraft, but out of all my plane spotting endeavours and travels, I have noticed that AF has the "dirtiest" fleet. Maybe it's just coincidence. Either way, I would never fly them after my experiences with them.
