I connected through LHR from a TATL yesterday and was very concerned to see that they have removed all fast track channels to domestics. When I asked at the BP check what had happened the lady said she thought it was permanently removed because the queues for non-priority were too long.
I will see how this goes. I hate having to wait in line - so much so that most of my short haul from MAN has been on other carriers (about 1000 TPs worth) since they removed priority boarding.
With this change at LHR if it does transpire that fast track domestic transfer is permanently removed I shall be reconsidering my preferred carrier for all travel. I do have to connect for most of my long haul travel ... it need not necessarily be LHR.
