While reading your leading article "Opening Skies" (Flight International, 28 May-3 June), I was just wondering with what kind of money British Airways could buy a controlling share in American Airlines, and where BA would stand today if it had not been protected for years by the "ugly" Bermuda 2.5 bilateral agreement between the UK and the USA.

I was interested also in the statement by Don Carty that he favoured cabotage freedom "so long as it is reciprocal". Reciprocity is the essence of bilateralism and I imagine that Don Carty excludes such an arrangement with, say, Singapore or Luxembourg!
