The schedule for the KLM flying looks like the same mess in the making as the initial Air France operation. Even if the Teesside crew end up in Newcastle every lunchtime, the Humberside crew land in Glasgow every lunchtime and then end up sitting there for 24 hours until the aircraft comes through again.
This will be a very hungry operation for crew resources and as has been seen lately, Eastern isn’t exactly flush with crews. I don’t think this looks especially promising.
