Please see this post I have linked for some information on changes to Flybe/Eastern Airways operations from Durham Tees Valley Airport.
Durham Tees Valley-7
From the public comments made by the management of KLM cityhopper and Loganair it seems like they happy with Durham Tees Valley airport operations. I have not seen or heard anything publicly from Flybe/Eastern Airways management but it seems like they plan to continue at Durham Tees Valley Airport from looking at the planned changes to the schedule.
It seems like a lot cancelled flights are due to weather and crewing issues and it's affecting all airports not just Durham Tees Valley Airport.
