BA domestic GB services - while service is Y only IIRC can be purchased in J (earns J miles etc).
thanks! CA now removed from "fy", but I'm in two minds whether to add the BA domestics as "jy" instead of the current "y". It depends whether being accurate as far as the points/miles is better, or setting the right expectations for the lack of onboard J. (the "Business UK" fare does permit lounge access, so all that's missing is the separate cabin onboard)
