Ok, I'll contribute. The Ab has a slightly less cost/seat mile than the 737-800. Besides one AC type can modulate lift based on demand. 124, 150, and 187 seats respectably. A perfect AC for Caribbean and/or C. America. I foresee MIA getting heavy on ABs. Look for a shift in 737s to DFW and ORD and swiftly replace the MDs. 330s to increase Middle East flying prob. more Tel Aviv, and possibly DXB. With E. Europe dest such as Moscow in the cross hairs. The 777s will see re-deployment to Asian markets as they become available. Its a long legged AC, and S. America is somewhat short for its mission. The 767-200 at USA will probably be gone by 2nd or third quarter next year. Its flying replaced with 330s. The 190s will replace much of AEs ORD and DFW medium haul market. Possible new 190 markets FLL to serve Caribbean. SJU,SKB,PUJ, POP, SXM, etc, but only IF FLL can provide viable US Customs service...PHX will most likely replace many short to medium haul markets with the 190. Possibly more 757 flying to augment Hawaii service. And finally ALL USA 737s to leave the inventory by 2nd quarter of 2014..And that is my prediction..
