ian23, thanks for the clarification.
Low cost is not true cost
Very true, which is why I try to avoid using most of them as much as possible, especially Ryanair whom I regard as the masters of hidden costs. Sounds like BMIbaby could be almost as bad though....
For what it's worth I have used Norwegian quite a lot and as far as lo-co carriers are concerned that are by far my favourite.
Hope you eventually got an answer from them.
