Hmm have to disagree that Cardiff is the WORLD's worst airport!! It is handy for locals...flies to the most popular leisure destinations (as after all it is a majority leisure airport!)the security are better than many airports I have travelled through (have you ever transitted to the US through AMS...enough said!) but they are after all security and therefore not there to pass the time of day.
The departure lounge, although not packed with entertainment, is spacious, clean and practical, and (sorry to disagree) the retail opens for all departures until the flight is called, with minor exceptions!
Would fly from there everytime...if only the flights were cheaper
