I'm planning a visit to Cardiff this April and wanted to ask some information. What is the nearest London Airport to Cardiff? Because I checked for ticket prices and direct flights to Cardiff is so costly. I'm thinking of going to London, Manchester of Edinburgh first but most probably I'll end up with London. I heard there are three airports in London. Which one is the nearest and how much would it cost me to take the train or bus? I wish you could help me with this.
