IMHO, the real bug is the non-correlation between used & new prices. In GW3, I can buy brand new A148A for 15M piece, while used are around 20M. And a buddy from my alliance had to raise the price of its 5 yrs old A148A to 17,9M so that I could purchase its plane.
That planes that everyone wants are going up to insane prices is really normal, IMHO. It should push you to look for alternatives. Some of the big boys in GW3 still buy A300s. Because, despite their higher functionning costs, they are (1)available & (2)cheap to build(production line has been optimized, continuous build from 1989 to 2013 and ongoing).
