Getting to BA

When I first started planning my trip to BA I was surprised to discover how few options there are for getting there. Particularly if you want to go direct from Heathrow. As it is, we are going via Frankfurt on Lufty, but I had expected the LHR - EZE route to be better served. Now, I've just read that BA are adding extra flights to that route from November. They are the only airline that offer the "direct"route, although they all require a stop in Sao Paulo. They're also adding flights to their London - Rio route. Bless 'em.
