We have a trial going on at the moment which involves the aircrew reporting the STAR they are flying on 1st contact with London. It is only certain airlines on specific STARs but it does seem to reduce the controller RT and take up has been around 70% in the first month.
So come on all you BA and BD crews on the LAM3A STAR let's make it 100% as soon as possible and get the trial extended to all airlines on all routes.
