So has LM grandfathered the LHR slots used for the MME service by now?
To me, it always looked like a pretty smart business move for regional airlines such as Loganair or Aurigny to pick up some of the LHR-slots freed up by COVID19 and try to grandfather them by opening short'ish domestic routes with the help of unsuspecting local authorities willing to cough up subsidies - for a service the airline never intended to operate in the long tern, but only to be able to cash in on those slots as soon as demand at LHR picked up gain and carriers that had to give up slots at LHR were interested in resuming services and forking out money to get hold of slots again.
