Cardiff will never learn. It never has. No point whatsoever in paying out stupid sums of money that it can't afford to waste to offer improvements to nobody.
Need a good deal amount of airlines and I'm afraid it fails to attract them. Big problem is the poor catchment area and the 2 biggest brands down the road at BRS who offer flights generally daily to most places across Europe.
Face it, the airport is stuffed and doomed to remain a quiet seasonal airport for the future unless someone drops a bomb on BRS. That's the facts and regardless what anyone says it isn't changing anytime soon this decade, I'll bet my entire career earnings on it!
