In his letter to customers regarding the proposed US Air/Delta merger, the CEO says one of the benefits is:
"Participation in one of the world's largest airline alliances, opening up even more of the world for your travel"
I'm Premier Exec with United and I live next to DCA which I use for short haul travel on US Air. I'm fairly close to IAD which I use for long haul on UAL. I accrue all miles in MileagePlus. Clearly I hope that the alliance that the "New Delta" sticks with is Star Alliance and not the pitiful looking SkyTeam.
Which one do you think he was referring too?
