I fly regularly with BA tickets on BA code share with IB metal. Several times I have had to call the Gold Line to complain about IB, and each and every time I get sent packing to IB, which I have now come to understand is a way of palming off my complaint to a carrier with zero customer service, staff with no manners and whom are the most ignorant bunch of benthonic crawlers I can think of... Even BA claim they have no control over IB...
