These are from LCY.
BA are abandoning the VERY popular route from LHR after many years of service and reinstating flights from LGW that they stopped a couple of years ago due to competition from EasyJ AerL Monarch etc.
Their LHR flight is immensely popular.
This means that LHR/AGP is NOT served at all.
So NO connections to the rest of the world from AGP via LHR – shame on you BA !
