It will be interesting to see. With the American Express offer on TPs it perhaps indicates that BA is now ascribing a cost against them and is willing to sell them, making them tradable. Wrt BA Holidays, it will become a commercial decision of whether the cost of double TP is lower than the benefits and/or it gives them competitive advantage vs the likes of Expedia, etc... A lot will depend on how it all fits into the IAG strategy and growth of BA Holidays as an IAG-wide 'platform'.
