King767 and Falconflyer have answered the question. King767 reiterated exactly what I stated in a previous post.
The A306 makes a nice fit between the 75 and 76 for UPS. It allows the 76 to do what it was bought for
As far as the MD-11 what CX747 stated reducing the amount of A306's. UPS has a firm commitment for 30 A306's till 2008 and options for 30 more. We won't know about the options until then but there will be atleast 30 buses in the fleet. The MD-11 purchase was for UPS's long range fleet to complement the current 747 and 767 fleets. The A306 was soley purchased for regional wide body lift, not long range lift. With the China routes starting in April UPS needed extra long range lift. Another 747-200 has been added to the fleet. 13 MD-11's to start with options and also more 747's possibly. There have been talks about 747-300 conversions like Atlas and also 400 and 747x talks also.
Happy New Year!
