The Importance of a B5 Area in an Airplane

Hazel and James were asked to explain what a B5 area was for. Hazel said it meant 'bonking capacity for three people' James replied: 'This is crazy, I think Rocky's stupid' Belinda agreed that the space made sense - but how often did it get used? The pair then explained why Azair crew should not be allowed to use one of these areas on any flight.
