The BHX - NBE - BFS w pattern is plausible; there was a MAN - PMI - BFS w pattern when operations restarted in 2021. The lucky crew would position with EasyJet on a Friday, night stop in Belfast and then do BFS - PMI - MAN the following afternoon. The unlucky crew would do the earlier MAN - PMI - BFS, wait in Belfast airport and then position home with EasyJet back to MAN.
