This sounds about right
The plans to combine LHR and LGW have been around for ages, it's only the LHR unions blocking it that have stopped it so far.
As a crew member that has to drive past LHR to go to LGW to get a bus from LGW to LHR to operate a LHR flight, (which is then classed as 4 sector rather than 2 sector because of the bus, severly restricting the routes we can operate)
I am very interested in combining the two airports
It does seem an awful waste of resources to have trained crew that cannnot operate direct from another airport
