BC is dead right. Non revs in "J" is frowned upon to put it mildly...I heard from a gate agent @ YYZ the other day en route to LHR, that none other S Knowles has been involved in ensuring all non-revs are accommodated up the back and any deviation will cause ruptions...Anyone else hear this ?
As for me, I am all in favour of reclining in front of the curtain...
In terms of jumpseaters, have an agreement, got space, come on in. Simple.
