Thank you all for the replies.
It seems like everyone's path is different. From reading content on this forum, it's difficult to tell how many days an entry level regional FO will be away from home if they have to commute. Some people say 18 days p/m away, others say 24 days away. 24 is a lot more days away than 18.
Does anyone have any answers to how many days away I should really expect as a new FO? Or, is path ambiguity just something I'll need to accept?
