I understand what you are saying about BRS and CWL, however LPL and MAN works well, LGW, LTN and STN work well together, EDI and GLA. On that note I still think that EZY at CWL would work well... 2/3 aircraft based, same as baby, perfect...
I know what you mean by their B733's. Some of them are on leases, so would not be renewed anyway. I wouldn't know what flybe would do with the B733 when the E195 is their biggest aircraft, and carries what, 118 where as the B733 carries 148. Quite a large difference.
