Problem is that noon time flights for EADS make little sense. All those TLS services from other airports are timed to allow day-returns for employees after spending time at EADS Toulouse. So either the daily flight is so well paid that the airline can be relaxed about utilization or it will have to find other, more leisue-oriented routes from TLS to keep the aircraft busy during the day.
Just a idea but another option to could have been to use the aircraft to operate the BHX service . That would free the BHX based aircraft up to operate to another destination.
