I finally booked the flights and went for the light price regards earning avios, your unable to get avios from Qatar but you can from BA. Looking forward to the flight.

Check out the avios conditions on the links that Cathay provided me . I have to say the people looking after the twitter messages are very helpful and gave me a lot of information
