Hi Foggles,
Cardiff Airport is to the west of Cardiff.
As has been mentioned above Bridgend is around a 20 to 30 minute drive away from the flying club, Swansea is anywhere around an hour as you have to drive through Swansea town to get from Bridgend to Swansea airport on the Gower.
Park on the southside which is the club area of the airport, if you park northside then you'll be charged a astranomical handling charge.
The ATCO's at Cardiff are all friendly to us G.A. types.
Oh and if you're taking the ILS into Cardiff on Runway 12 see if you can spot a large fish at around six miles out that someone has carved into the hillside recently. (Not me guv).
Best wishes,
Charlie Zulu.
