there are no 737-300 free anywhere in the world at the moment. any that can be maintained in australia that is, without major expense. the only machine about is the airwork 73, but its so expensive, and with airwork's past record, no one in their right mind will touch it.
From a quick gathering of whats available there is approx 45+ B737-300 aircraft that are either for sale/dry lease/wet lease ACMI
if an airplane is listed as immediately available it means it is parked in the desert in Arizona or somewhere.
Thats wrong, Airline in America is currently limited flying 10 x B733 aircraft that are up for sale atm.
The good news for the bottom end of the market is that in the longer term old 737's should get cheaper as Air Asia dumps their big fleet on the market.
Maybe / Maybe not if they are in good shape they will attract higher lease prices if they are in **** condition then maybe
And none of the currently available are ETOPS. Qantas and Air New Zealand would not be so silly as to sell theirs in to the local market. Makes trans Tasman expensive if not ETOPS.
What about those 8 on speednews?
