BKK to Dublin via CDG. Thirteen hours of hell - I managed to get 4 hours sleep from take off which left 9 hours of boredom and fidgeting in this tight cramped seat with no IFE system. I only flew with AF because of the Hanoi destination they offered.

Unacceptable legroom space for a 10 hours flight and I am only 1.75m tall, I can imagine what happened with large size people: airliners should urgently revise their Economy class cabin configuration layout in order to assure more comfort to passengers

Most uncomfortable flight I have ever had. Seat were so close together, that it was impossible to stand upright in the row. Avoid Air France A340's if at all possible!

Bangkok to Hanoi, seat 16J. Seat right next to galley, so there is plenty of movement in/out the galley and a constant chit-chat by flight attendants in the galley. I would recommend not sitting right next to the galley if you want more peace and quiet. Seat back video means this aircraft was configured with Air France's new seats and configuration.

Seats 61C and 63C on the upper deck. The upper deck seats are far superior to the rest of the economy seats on the place

Would never travel long haul with Air France again! 11 hour flight to Mauritius (October 2007) apart from seating - no individual screen on seats, English subtitles of film, seated next to the galley so had food smell, people constantly passing by to help themselves to drinks and snacks, food mediocre but very surly flight crew who hardly smiled.

The only reason you can see the screen so well was the fact that it was less than 10 inches in front of my eyes

Probably one of the better economy class seats I've travelled in. Bit cramped with the person in the seat next to you but nothing too bad. The tray table is quite small, I found myself stacking things on top of each other when eating the meals. TV was easy to see, even when reclined.

The middle seat in Economy has an entertainment box located under the seat - blocking up to 75% of the leg space for the person sitting behind. On a 10+ hour long haul, this is unbelievable uncomfortable. On the return leg (also B777) I picked the isle seat so as not to have this problem, only to find that on this particular aircraft, under the middle seat was free and the entertainment box was under the aisle seat.
