Good column by Jancis Robinson (BA wine consultant during the golden age) re airline wines in today's online FT (will be in Saturday's print edition). This FT gets an honourable mention, BA doesn't come out well.

In 2009, Willie Walsh, then head of BA, abandoned the policy of choosing wines on the basis of what they tasted like, cutting costs by appointing a single exclusive supplier for each of the three classes.

BA’s wine-buying is now in the hands of two young Frenchmen working for the parent company IAG. They seem to have had little experience of wine-buying. The dire state of their budget can be judged from a recent discussion on Flyertalk.com. The Villa Maria Sauvignon Blanc on offer in BA first class was spotted in Morrisons at £5 a bottle, two for £9. (BA says it is no longer on the menu.) In a recent first class tender, submissions that were over €6 a bottle from the cellar door were rejected. (The budget for forward buying of claret used to be €25.)
