Thanks Guv
I just tried it a miraculously the dates are available on BA.com (I have been looking for at least 2 months now with with out success) but the taxes and fees work out to be about 300GBP per person plus 60000 miles. I may as well hold on for a cash booking deal which would come in not too much more, so I feel thats just wasting the air miles.
I know that AA only want only $150 pp to use the same airports (and the same flights) how come BA can charge so much. I must admit I didnt ask Iberia what the taxes would be as I am not a freq flyer on the airline.
This really turns me off BA.
