Jorik - yields are not publicly available, but you can find number of passengers each month on (almost) any route out of a UK commercial airport by going to the CAA website and looking at the airport statistics section. Initial passenger numbers for Oct 2013 due to be released provisionally some time this week. Given passenger numbers and knowledge of how many seats were available for sale you can obtain load factor.
