AFR really needs to curtail the number of aircraft types in its fleet. Currently, there are:
737-200, -300, -500
A319, A320, A321
B767-300(2 engine types)
B747-100,-200, 300, 400
-A318s will replace the 737-200s. Ill bet the 733s will be returned to the lessors in favor of more A319s.
-The A310s and 767s will be replaced by a common type, either 767-400, or A330-200. Tough decision. The 332 will have better fleet commonality with the A343s, but in a sizeable order, this advantage is lost. An order for 15 a/c is expected. Perhaps Boeing will try to boost the 764 order log. cheap prices and quick availability are big plusses.
-More B772s are on order, and will replace the last of the 747-100s by the end of the year.
-The 773s/A346s would replace the 742s and 743s, and allow for growth. The GE90 would allow for 1 less engine type to be added, and a common type rating.
Overall, the 777-328X(ER?) seems like it will be a good idea for AFR. KLM is rumored to be very interested as well.
The 'new' fleet would contain 735, 318/319/320/321, 764 or 332, 772/773, 744. The number of main types will be reduced from 13 to 5. The number of engine types will be reduced from 11 to 5. All of this consolidation would seemingly improve efficiency, and therefore, profitability.
