To say LTN has escaped the worst of the delays is not my experience at all, in fact the exact opposite. The two main carriers out of LTN seem to be having a major breakdown with their respective handling agents. For one in particular, the airport operator, rather than the handling agent, seems to trying it's best to keep the show on the road due to the lack of staff at the handling agent who do not appear to be able to retain staff due to the poor renumeration, this needs to be immediately corrected. Currently it seems to be the default to have no marshaller, no manpower to position steps, no baggage handlers, no push back crew etc. This is resulting in missed slots, passengers and bags stuck on aircraft for unacceptable lengths of time (regularly 40+ mins), crew running out of flight duty hours, knock on delays and cancelled flights etc.
