One big saving and highly unusual aspect of this is Aspire Flight Training. A group of the airlines training Captains has been quietly revalidating the licences and SIM checks of many of the Q400 pilots. Getting former MPLs converted to ATPLs and other excellent work. Its virtually unheard of and shows the family spirit and positive attitudes of those Trainers and crew. I sincerely hope Flybe 2.0 contracts Aspire for Crew Training at least initially. So, one of the major initial costs of starting up is virtually absent.
I wish all my former colleagues the very best of luck getting back into the air!
