Why do we even think there is going to be a shuffle?
I havent heard or seen anything indicating that there is going to be a major shift in flying yet. Most of the time, I hear that the "marketing hours" arent complete until half way thru the previous month...
This could be as minor as moving regional flying from JFK to LGA; and having more flights flown by mainline like DL is doing in ATL.
From a 9E perspective, MEM has barely any flying left as compared to what we used to fly there. I would be suprised to see MEM go but, I wouldnt be suprised to see us move to LGA from JFK - Or our union sign yet another LOA and screw us with a co-terminal base.
