Can't be a sub for the bmi regional as there 2x daily flights are shown as operating a normal schedule these look like extra services/charters.
If it was a sub for a bmi regional aircraft wouldn’t Loganair just run the flights using the scheduled BD flight numbers and the current slots instead of using the LOG flight numbers and totally different flight timings?
A 3rd flight is now showing as been operated by Loganair between LBA and GLA on Tuesday.
