The $2 was a left over from an earlier regex that I was trying before I 
found out the the query string is actually sent separately to the URL. I 
put %1 in and it now works! I also got rid of the first grouping as I 
wasn't actually using it, so the final rule is as follows;

RewriteCond %{QUERY_STRING} dest=([A-Z]{3})
RewriteRule ^bin|cgi-bin/flight-search.cgi 
http://www.charterflights.co.uk/charter_flight.php?to=%1 [R=301]
