Thanks for that link to the ACL Report, BasilBush. It seems that my original list omitted the withdrawal of one of the daily Swiss flights to Zurich and cutbacks to ABZ and SOU by FlyBe. So a new total of over 22 departures (44 movements) per day required to be offset by new services. Interestingly, ACL has elected to use the same format as myself in displaying the change to the MAN-ATL operation: Delta is shown as "cancelled" whilst Virgin Atlantic is listed as a new service.
