My opinions differ to yours redfield.
None of us want a/c to go tech, and certainly dont want delays of 27 hours plus. In these cases airlines need the backing of their handling agents (that incidentally get business from FCA 12 months of the year at BRS), to help prevent delays creeping further. If an a/c is out of schedule the last thing you want is a 90 minute turnaround due to lack of ground staff.
Its very apparent that servisair take their monopoly of Bristol airport for granted, if there was an alternative handling agent in attendance would they have such a relaxed attitude. I think not. 12 months of neglect in delay situations would force airlines to 'switch'.
Besides, passenger handling staff and dispatchers have no issues with staying on to handle delayed flights so why is there an issue outside the terminal building. Thanks again to the fire staff!!!!!!!!!!!!!!!!!!!!!!
