I've been having some issues switching aircraft over, leading to a drop in profits for no explicable reason.
For instance, today I took delivery of a FH-227B, which I have used to replace a leased example of the same type of aircraft. I've done the Close All Routes thing, but when re-opening them seconds later the 100% LF requires lower fares. For instance, between Batam and Taipei, a route I fly with no competition, the following happened:
Before
Batam - Hang Nadim Taipei - Taiwan Taoyuan Intl 0.5 100% €1,105 €59,912
After
Batam - Hang Nadim Taipei - Taiwan Taoyuan Intl 0.5 100% €1,030 €55,712
Quite frustrating to lose £4.2k when all I've done is swap a leased plane for an identical purchased one. :?
