Eastern applied for MME-LHR and LBA-LHR.
Loganair applied for DND-LHR (which I think they always do?), IOM-LHR and NQY.-LHR.
You can change destinations pretty easily so I wouldn't take it as gospel that's what these are. Eastern's LBA-LHR could easily be covering NQY and Loganair's NQY-LHR could easily be covering MME and none of us would be any the wiser until or unless this ever sees the light of day.
