This will be a "defining moment" for AA, because it will force AA to show us ALL what direction they are truly headed in.
YES, if One World falls apart, then it's pretty much becomes "Game-set-match"
On the other hand, Absolutely DOMINATING the air corridor from LHR to BOS/NY/ORD/DFW/LAX then on to NRT(and beyond) is VERY "interesting" to say the least.
LHR-NYC-LAX-NRT are THE Most valuable air routes in the World.
I don't care HOW big DEL-DUH gets, because on their Best Day/A-Game, DL could Never beat AA in a (air) Fist Fight !!
The Real question is, ....Does AA feel like fightin'......!
