I vaguely recall that in the heady 2017 days of the TLL run, one was able to construct interesting multi-stop itineraries involving codeshares around Scotland.
With these new routes, does something similar become possible again, albeit perhaps to a more limited degree? If I recall correctly, as Loganair doesn’t have J those only returned 20 TP per leg, so it wasn’t a huge earner, but could be a fun set of trips (and the base TLL fare was so low that it remained good value IIRC).
Edit: an example might be ABZ-LSI/KOI-GLA/EDI-LHR-ZZZ and return rather than ABZ-LHR-ZZZ
