I dont think BA do want franchises in the UK as they chose to end all previous ones. I have heard rumers that loganair wanted to continue with BA but BA declined. Comair in ZA I think is also part owned by BA am I right?

Anyways I have always thought that T3 would make a good little BA franchise. They already use the BA lounges at various UK airports and offer the same level of onboard service. WOW could also be another good one I think they get ground ops done by BA at LGW?
