Just in case I'm missing something here, could someone confirm that I've got this correct.
Aircraft PVG-LHR diverts to LGW. Late in the evening departs LGW for STN. When airborne request diversion to LHR. When told that it is after the night jet ban, a low fuel 'emergency' is declared and the aircraft lands at LHR, the original destination.
Have I got anything wrong?
