With the World Health Organization declaring the swine flu virus a global pandemic, British Airways and Virgin Altantic are taking no chances.
The airlines are taking measures to stop people with swine flu from boarding flights.
While, British Airways said there had been cases where people who had checked in with symptoms had been advised not to travel, Virgin Atlantic said victims would not be allowed to board its planes without a fit-to-fly certificate from their doctor or a hospital, though there had been no cases yet.
Britain has the worst swine flu figures in Europe with 29 deaths and a huge rise in the number of cases.
The World Health Organization has declared the swine flu virus a global pandemic as about 98,000 cases have been documented worldwide.
The virus has claimed 440 lives and more than 120 countries have reported cases of human infection.
