re: parking in LCY - what kind of times are proposed? Is it likely that the EB leg could simply be crew-change/fuel/go at LCY with daily checks done in JFK? It would lose some business time but if the 318s are fitted for satellite internet/cellular that could be less of a problem.
If I was one of those bigwig types I'm not sure I'd want to hear that my 318 was tech in EDI to save parking charges. The only upside I can think of to the 318s subbing in on BA LCY routes could be a sales pitch to those based in Canary Wharf who fly to the US occasionally but more often to Europe/UK. Those flights could simply have Y unbookable to spare the "riff raff" effect.
