The NEOS A/C are set to be re-configured to offer Bus/PE/No-Frills, but BUS won't have sleeper seats I think. The service will be much the same as GSM provides, full meal service, etc.
The B752 will operate the YHM flights from GLA and the B738 will still operate the BOS flights over S07.
The 1st B737-700 that is currently at GLA will operate from ABZ over S07 and the 2nd is due Spring and will operate from MME, where it'll join the 1st B733 based there from Mar 07.
