I live in Cape Town and recently made a trip to the UK with British Airways. I received my gluten-free meal before my husband and enjoyed the pasta salad. Unfortunately, when my husband's meal arrived, I discovered that he had the same side salad as mine. I complained to the steward who apologised and said the meal had been prepared in Cape Town and he thought that was where the trouble lay. So if you are travelling out of an airport from a country which doesn't offer clear gluten free guidelines, be careful. BA were apologetic and have offered me a £100 voucher but it doesn't really compensate for being glutened!
