I would be extremely surprised if Song adds anymore cities. I would be surprised if Song was not in the process of being phased out by the end of the year. I think the Song experiment (as well as DL
's experiment on some routes using redeployed Shuttle a/c still in Shuttle setup) will be some of the basis for a retooled Delta. Delta may launch JFK
as a future mainline route, as they are considering more and more flights that don't go through ATL
. Note I said mainline, as Grinstein is looking to put the RJs on flights under 2 hours.
