myrddin, OK, I'll rise to the bait! My understanding is that not all the B727s will accumulate dust as soon as originally planned & 1 or 2 will remain on the IAOC for ad hoc work. Add the Hercs & the management contract for the Aeropostal A300s & I reckon the IAOC will be reasonably well used. As for your comments regarding the A300s, I guess you're a Boeing fan 'cos the Busses will soldier on with the likes of DHL for quite a few years yet.
The more I look at it, the more it seems that the management of both companies are trying their best to ensure a viable future for everybody involved. Makes a change these days! Then again, I'm a cynical optimist(?).
