WOWBOY - the very same BBC that mentioned the base review stated that there were bases in Cardiff, Doncaster and Bristol - none of which are bases! They also said that Flybe operate to EDI and GLA from LGW so I'd suggest that we take that particular article with a pinch of salt.
(The current BRS base is purely to operate the SN flights to/from there and will close if/when the SN contract ends or if it is altered to remove BRS. No BE flights are operated from the BRS "base").
