So conversion can transfers the stars from the old plane to the new plane. Improving the old plane is cheaper so doing it earlier can save screws and equipment rather than improving the more advanced plane. A very detailed explanation. Thanks Fackifiknow. Btw I just saw those are explained at the top of the aircraft conversion page. That was careless for me to miss it. XD

Just have to make sure i dont accidentally upgrade the plane into something else then.

Suddenly the quest chain become more tedious :(   And I thought the Flight Deck quest was already tedious.

Also, does anybody has any idea that any of these plane conversion quest be locked again by the monthly quests if i dont clear them on this month? or do they stay unlocked for good?
