Lappaceous

I already own msfs2020 and I am wondering if my premium deluxe aircraft will carry over to the new sim. I mainly just want the 787 but I don’t want to purchase the expensive bundle again. I am also wondering if the sim is genuinely good in free flight on pc. I mainly just fly single player in an airliner and I just want to know if the sim is good for this since the last time I looked into the sim I heard some bad stuff.
