Dull ugly and (worst of all) the most unreliable and infrequent airport-to-city centre transport system of any airport I have known. Little wonder the airport is a white elephant recently bailed out by the Welsh Assembly government. You will arrive and discover that there are no taxis (these must be ordered) no trains (although there is a train link some distance away requiring a taxi!) and (most shameful of all) buses that depart once every 45 minutes! The latter are poorly signed and the whole this is a fiasco. I arrived on a flight at Cardiff Airport at 7.30pm and the terminal was closed. We were escorted through an area by airport staff to an exit and dumped outside to fend for ourselves (see above about lack of transportation). It was like flying to Uzbekistan circa 1953! I urgently recommend that you fly to Bristol instead then take the train. Failing that just don't go to Cardiff.
