I assume they will announce their response in the next few weeks.
I expect the response will be increased frequencies on routes the Baby are serving already served by BE i.e. Birmingham, Cardiff, East Midlands, Manchester and probably London-Gatwick. I assume BE will attempt to wipe Baby out of BHD.
When BE moved to CWL they did far better timings and prices than WW did and managed to wipe baby off the domestics from CWL. Now BE have to themselves GLA, EDI, JER from CWL and I assume they want Belfast all to themselves.
