The Delta shuttle is operated by delta.
Does delta operate any E75's? As far as I can tell, It's not currently a plane they own.

So my question: is the shuttle switching to a delta connection?
If it is, I don't think you won't see the same FA's.
UPDATE:
Okay I just looked myself, the flights will be operated by Shuttle America.

and thank you mersk862, I was mistaken.
Regarless, they both leave from Gates 23-25, which has to be the worst gate (for on an on time departure) in the history of aviation.
