Just sat on the jumpseat listening to the captain tell me that I can log all my SIC time as PIC time since I hold a type rating for it now. I didn't really get into much with him cause I haven't been up to date much on logging flight time rules in the last 4 years. Could I log it is PIC even tho the captain is the designated PIC and I'm just a lowly FO?

Anything would be nice at least it will be a change in the mood of what's going on at what airline.
Thanks
