Funny thing is low-average tier planes are able to gain a lot of slots in a very quick succession.

My Su-33 wich has a base of 20 slots on all areas has gained 5 slots and the next slot still needs around 9000 points to gain another one. You can pretty much make an overkill aircraft set just by upgrading your plane to a high level and getting the easy slots. My Su-33 is lv.12 now and has 27 slots in each area, it decimates the million credits costing super planes.
