Unfortunately there are always some who clutch at straws when it comes to Cardiff and it is so easy to start rumours up regarding the airport. We would laugh when for example Easy Jet would divert to Cardiff from Bristol and await the " are Easy to be based at Cardiff" type posts.
Airlines recruit in larger cities all the time it doesn't mean that a service is to start up. That doesn't however mean that they wont start a service up either and contrary to Birdscarers remarks Cardiff isn't an Elephants Graveyard and the future may be quite rosy.
