Have now heard this from two reliable sources (albeit neither of them directly at Air Scandic). The plan for the DC10 apparently includes operating CT2's South Africa flying this winter given that the AV8 operation will no longer exist. Scandic's A300s are going in October as now finally due for the D Check.
MyTravel DC10 flying was originally planned to be mostly Montego Bay and one Sanford per week. Also haven't heard what the MYT reaction to the arrival of bmi on MAN-Las Vegas is going to be - apparently this was one of the few decent money-earners last winter.
