Clarification
As a couple of you have said these rumours abound at all times. But what do you mean by closure. If you mean closure of the route then I think not, however, if you mean closure and lose of those airports with BA ground / ramp handling staff then you may be nearer the mark. I am sure that the near term plan must eventually focus on LHR / LGW BA ground / operations/ engineering & ramp with the regions sadly disposed of.
BAs' plan for outsourcing has ground to a snails pace over the last few years beacause of the industry problems but that does not mean the plan has been shelved. As many of you state Waterworld / Compass support a massive number of staff and they will make sure that they are the last to go which means that outstations will bare the brunt of job losses.
