flew quite few times the 747-400 mixed on KLM AMS-DXB and return, as well as AMS-ORD, AMS-SFO. Always great flights. Flying economy comfort on KLM was great, as they had the galley on the side, meaning it was a small cabin just over half the width of the aircraft, 5 seats abreast (3 + 2). Very cosy
I'd forgotten about that unusual KLM layout! It was almost like being on a DC-9/MD-80.
Actually can't remember my last 744 trip... Might have been KLM YYZ-AMS in J. Yes I think that was it, and it was at least ten years ago.
