its interesting. i checked with consolidators and cooke/am ex and so on. their prices... when added up is not cheaper for first (lx and air france and BA). i can book with another service that uses miles points so i would not get the points and they too are not cheaper at the end of the day.
i was told if i want to go business on BA i can apply for a BA visa and get 2 for 1 but that takes a month to process and i'm sure stuff will fill up and go away by the time i am able to book. also, don't think their first will be cheaper for 2 for 1.
might just stick with the lx and am ex plat 2 for 1.
