BA Continues Gatwick Pull-Out

From Airwise.com
British Airways is making further moves to scale back its long haul operations at London Gatwick and transfer flights to the UK’s biggest airport, Heathrow as it seeks to cut losses.
The airline’s winter schedule will see transatlantic services to Denver, Phoenix and San Diego move to Heathrow Terminal 4. At the same time BA is increasing daily flights to New York JFK from six to seven. The number does not include Concorde services.
Two African services, to Harare and Lusaka, are also being switched from Gatwick, but Caribbean service from London’s second airport survives and there will be two extra flights to Antigua from Gatwick, making this a daily operation.
Three short haul routes making the switch are to the Russian city of St Petersburg, Tripoli, in Libya and Sofia, Bulgaria. BA is also stopping its Gatwick-Athens service this winter, but will add an extra flight to the Greek capital from Heathrow.
The airline is boosting frequencies on its routes from Heathrow to Cape Town and increasing capacity on flights to Middle Eastern and Asian destinations by using larger aircraft.
BA says that flights to the Pakistan capital, Islamabad, suspended after last autumn’s terrorist attacks in the US, are not being resumed although it intends to restore the service at some point.

What I find strange is that the Bermuda II agreement stops these destinations from being served from LHR,so what the heck is happening?
