To add to what was said above, it seems lately even a jr line holder can be home every night. People always drop the turns in the front and back of trips. After the first week trading opens, there are tons of minimum day credit trips available. With some luck a jr line holder could conceivably make an all daytrip schedule, albeit you'd be working 18/19 on and 12 off. It's better the other way around but you'd need to be in the top 30% of the base FO list for that. At least this is how it is in LGA.
