EI announced several new US destinations today. I've noticed in the past that ba.com sometimes offers me EI options to the US, particularly if I put LGW as the origin.

As of just now I picked some random dates I can see they have the new routes on but can't currently see them on ba.com out of London either as code shares or otherwise. Is that a) because the wheels of IAG turn slowly and they'll show up sooner or later or b) because not all EI US destinations get sold like that?

Secondly are they likely to (ever) be bookable as ba reward flights?
