well, i dont think that those 2-class F seats have got anything to do with First Class (nor was the price particularily expensive) but I'll obiously happily take the tier points.
i was trying to find a table (which I am sure i have seen on ba.com before) that mentions the distances so naively assumed / hoped that by adding an extra segment to the total flight, i might earn more that way. good job i didnt go for a 2 flight outbound journey!
