We're hearing the Jet Blue rumor alot at Delta. I'll believe it when I see it. In our iteration of the rumor, we are primarily interested in the terminal and the E-jets.
The problems with this are: (1) Are the E-jets' problems worked out? (2) Do we want a new aircraft type? (We've been working toward a 777/767/757/737 fleet) (3) Will Delta's operation fit into that terminal? We're talking alot of wide bodies put into a terminal designed for narrow bodies.
FWIW, a staple job is highly unlikely. Why would we want an angry subgroup of pilots in our midst? A fence would be very likely, though.
