. . . . they are same size on a -900 and a -1000 so the extra weight of the -1000 is important. From Wikipedia (no idea how accurate this is):

Height so air density is just a part of lift function (speed, lift coefficient and AoA of the airfoil ). But in high altitudes, there is a problem with speed (M number) so the limit of the ceiling.

Do not forget - less air - less pressure, i.e. less power forward needed.
So all is TRADE-OFF !
