It's on the intranet. Double daily New York on the A318 with 32 business class. The actual airport has not been decided.
The actual product hasn't been decided yet, either. I would imagine the traditional club world seats may be too heavy.
The flights will be operated as mainline. I don't know what impact this will have on City Flyer crews, the intranet only mentions BALPA, not cabin crew.
The outbound flights will require a fuel stop and that does make me wonder if this will be competative or not. I guess they know what they're doing
