Having a bit of a quandary. Mrs Lem and I are planning a round the world trip, and the standard Oneworld Explorer isn't providing us a couple of options for flights I know exist - therefore I would like to choose the Global Explorer option.

However, the link through to BA only brings up a FAQ page, and the RTW option on the multi-city page sends me back to the Oneworld explorer.

Is there any way of getting BA's site to accept more than six flights, or do I have to call up?
