The 75 is a great airplane that can't be easily replaced. The number of opportunities for a capable airplane in western europe, caribbean, and south america are too big of a competitive advantage for us to mothball the whole fleet. The a321xlr has potential but with a hefty price tag and 5 yr delivery. These are paid off, known quantity planes with crews in place that know how to fly them. The 767 is going to be workhorse for another decade with few maintenance surprises. We know the 756 fleet and they are cheap lift if oil stays low. I don't see us parking anything but the hangar queens.
