Sorry AM.
Seems I was misinformed.
Is it just the NQY-LGW & MAN rotations that you do on the based Q400 ?
Wouldn't it make sense if the LGW route closes to use that based Q400 for other routes, ie MAN and then increase EDI etc to make use of the based aircraft ?
Either that or they will pull the based aircraft away and use a MAN based aircraft for that rotation.
