Air cargo booms: 747 freighters needed, but conversions unlikely

AS AIR FREIGHT recovers rapidly, consideration is being given to satisfying capacity lift - just as airlines retire their passenger 747-400s.
Delta and United are two of the more recent airlines to retire their 747s, while Qantas is the latest to announce that it will accelerate 747 retirement. Even British Airways, which will operate the 747 into the 2020s, plans some retirements this decade.
It has been suggested that these passenger 747-400s could become freighters. While air frames are lowering in value, conversion costs remain significant, and the great age of the 747-400s provides fewer years for costs to be amortised. The larger concern is the ongoing inefficiency and cost disadvantage of a converted 747 compared to a 747 built as a freighter.
