They are being either:
A) Super tight lipped.
or
B) Have no plans.
Most of us on the line lean towards B. It seems almost when the Virgin America deal fell through and the Long Beach customs fell through... they had no backup plans. They keep kicking the can down the road with everything (winglets, cabin refresh, E190 decision, LR/330's, Europe, Midwest Expansion, etc etc)
But hey, we announced EWR-SDQ yesterday!
