Bus to Boeing consider this.
I presented myself to the Doc at the EK clinic with severe lower back pain. The first thing he asked is , " What fleet are you on , Airbus or Boeing ?" , when I said Boeing , he said the clinic was aware of it as there are many with a similar complaint. The flight dech seat truly is a torchure device.
It especially significant , given all the ULH on this fleet. ( bare in mind when you go back to the torpedo tube to rest , you cannot stand upright in it either. So you duck walk and shuffle around to get to the bunk. You are unable to sit in the bunk as well. ..... and there are no other areas on board where you can sit comfortably.
The 777 is a great machine , but given the discomfort and deterioration in my health I would go back to the bus tomo.
