David, I feel it is important to define the total cost of delays … as I am pretty sure BA only looks at its immediate costs and NOT the longer term cost to its goodwill, future earnings, direct costs to pax, etc. There certainly seems to be quite a few disgruntled pax as contributors to this forum ( from my reading ). Also pretty sure that when these total costs are accurately estimated ( very hard to be precise) then the total sum cost of the extra equipment is easily justified. I think this is what expat is getting at. Its just that no-one ever appears to sum the total costs involved … only the here and now costs….
