Thankfully, the desert will not be filled with the 1000 plus all at one time, especially because even those airlines most loyal to Airbus will not phase out their 744s overnight. LH
for example plans to keep them flying for another 4 years or so before they phase them out, at least that is what I've heard. I just don't see why airlines feel the need to retire a plane that is not really replaced (the A380 is far too big to be considered an ideal 747 replacement), and is still farely young (the oldest 744 is something like 18 years old). That is nothing compared to UA
747-100s, which flew for over 25 years. My point here is that retirement likely will be more progressive...I doubt we will see 744s rushed into retirement.
