I believe Cardiff-Brussels is starting at the end of this month although I haven't seen any advertising for it.
Also rumour mill has it that the Welsh assembly is funding a round Robin of Wales
IE: Cardiff, Swansea , Valley, Harwarden.
Plus there is talk of charters, such as one offs as rugby and football charters.
All Rumours though, have also heard rumour of a Swansea- Paris flight, but really cannot see that one going ahead although I hope they prove me wrong
