A Severnside airport has been muted before but never got off the ground. In the end it would be unacceptable for Wales as a country to close it's busiest airport down and move it to England and Bristol would've never been closed down either. Both Cardiff and Bristol aren't in the best of places but Bristol has shown that doesn't prevent it from being successful. Provide airlines and destinations that people want to fly to at the right prices and people will use the airport. With Cardiffs increasing passenger numbers that is being proved.
