From my experience with BA Production on other aircraft, it matters little which variant comes down the line and my bet is that, if there is no associated limit clause, Delta will take the 300 (the 100 is very much slanted towards operating from London City & long, thin routes). My comment on available slots was over the entire narrowbody market including 737s & A320s and is even more valid with the latest delays in P & W Geared Turbofan deliveries which is effecting Airbus at least as badly as BA.
