Spot on, Neville & Icarus.
Something extremely important that the bean-counters are oblivious to and which is very prevalent right now, is damage to your brand!
Constant breakdowns running cheap old aircraft creates a brand reliability issue, no matter how hard working & good your maintenance team may be... "Can't see the forest for the trees", comes to mind.
A good brand reliability pays the bills many times over, hence investing in newer airframes as per Cobham (Emb/Q400) will see them in a more powerful position I reckon.
Happy landings
