B_T,
Some discussion in the below threads over the past couple of days re Eastern taking on Air Southwest, in the first link from #653 onwards.

Although the intention appears to be to run them as two separate entities for the time being there are already one or two anomalies that might need sorting out sooner.
For example, Eastern currently routes the last ABZ-BRS-ABZ of the day via LBA in both directions but no tickets are sold between BRS and LBA in either direction.
The Eastern service arrives at BRS in early evening about two hours ahead of the Air Southwest LBA-BRS.
Many thanks for your input on BD, BRU, LH et al.
