Keep your hangers, but upgrade your runways to the highest possible. Because, in v7 there won't be any skipping of runways (e.g. you buy RW2 skip RW3 then buy RW4 instead you will have RW2 then upgrade to RW3 then RW4 and so forth)!!!
Sell hangars???
They will dissapear anyway? Or do they take the number of hangars and replace them with stands?
Need answer ASAP, lot of money to gain!
