762s are gone by summer 2014 (last I saw.)
763s, about half (28 a/c) will slowly be phased out over several years the other half stay.
757s, all domestic birds will eventually be phased out over 5 years or so (about 70 a/c.) ) the International 757s (about 20) will stick around.

Current fleet count shows 59 763s and around 90 757s. 762s are down to around 10 and about 1 or 2 per month are heading out to ROW.
