Just answering the queries regarding Beauvais and Torp:
Currently a Prestwick crew flies daily PIK-BVA-OPO-BVA-PIK as an 'early' day.
With Porto becoming a new base I believe that Porto crews will now be flying the OPO-BVA which is increasing to twice daily.
Haven't heard this officially, but by putting two together it seems that Prestwick crews will be flying PIK-BVA-Torp-BVA-PIK. All the times match up with the good old 25 minute turn around and it starts around the same time as the Porto base opens.
