Security lines and joint responsibility
I agree with the last post.
While it is fundamentally the airport who is responsible for Security and the staff, surely the airline's customer service staff should have the slightest bit of customer care to be able to step in and help their pax when they are caught up in these lines.
This should be even easier at a small airport, especially one where BE is by far the biggest customer.
But, don't get me wrong. EXT should step up to the mark and get more staff or at least offer pax a free cup of tea as compensation as recognition for their bad value for money they provide the pax for their security charges.
