AC narrow body business class armrests should be made moveable.
As a suggestion and improvement to future hard product, AC narrow body business class armrests between seats should be made moveable.
The seat should be modified so that the mini drink table would be placed on the side where aisle or window is.
This way one can lie across 2 seats when the other seat is empty.
Sometimes I actually prefer economy flights when it is not full and when one can lie across 3 in a row (e.g last flight from Vancouver to Calgary of the night)
