'And yet another British airline flies into history!
Not really as they were still Virgin Atlantic flights flying under the title of 'Little Red' which was more of an advertising name for its U.K. domestic flights not the name of the airline which was still VS.
Virgin Atlantic's 'little red' domestic routes from LHR to ABZ, EDI and MAN were operated by Aer Lingus on behalf of Virgin Atlantic so no airline has gone into history just the title 'little red'.
Both EDI and ABZ were BA slots as part of the 9 in total under the agreement where as the MAN flights used Virgins own slots and were never part of the slot deal.
Virgin and Delta can do what they want with the former MAN slots but the ABZ and EDI will revert back to BA if no other airline takes them up as the slots can only be used for those routes but once there eventually back with BA they can use the 9 slot pairs for any route they want.
