Jenbel, if you haven't already got one, there's a 10,000 mile first use bonus after opening AAdvantage AmEx/Visa credit card accounts at
http://www.americanairlines.co.uk/i1...&title=uk/mbna
From then on, just use the card at least once every 18 months to keep your miles alive - well, say 16 months just in case.
The 20,000 bonus offer ended on 31 May.
