It’s an excellent measure in placed by the British airlines to turn back passengers showing swine flu symptoms.

So far, according to British Airways, there had been “very small number of cases” where people showing symptoms of the H1N1 virus had been advised not to travel following medical advice.

According to Online News (written by AFP), Virgin Atlantic said people suffering from swine flu would not be allowed to travel without a “fit to fly” certificate from their doctor or a hospital, though there have been no cases so far.

Britain’s health authorities are advising people with symptoms to delay their journeys until the signs have cleared up.

Health officials said Thursday that 29 people had died in Britain after contracting swine flu.
