EK Boeing fleet - slightly uncomfortable seat, great routes, magic aircraft.
EK Airbus Fleet - slightly less uncomfortable seat, piffy routes, never flown it and hope not to at EK ......
The choice is not difficult.
If you are given the choice by EK to change from AB to Boeing , do not let the comfort of the seat influence your choice. A little backache from a 777 seat is a Small prise to pay for a better roster and lifestyle at EK.
Time for my daily yoga!
