In December 2012, following the acquisition of British Midland International by British Airways, Virgin Atlantic was awarded slots to fly domestic routes in the UK from Heathrow Airport, ending the monopoly on these services that BA had held since its successful takeover. Aer Lingus supplied on a wet lease agreement four Airbus A320-214 aircraft (painted in Virgin's colours but under Irish registration) as well as crew for these services, which operated from London Heathrow to Aberdeen, Edinburgh and Manchester. Services began on 31 March 2013 to Manchester. This wet-lease agreement ended in September 2015, as Virgin Atlantic cancelled its domestic services.
