Spoke to a WW CSD last night who'd just flown in from NRT, apparently loads of sectors have been flown 'empty' including NRT/LHR's and BA are trying to find routes to sub charter where the 'competition' is 'poor' ...e.g NBO. Her view was that BA was too frightened to admit that they cannot take on crew issues for fear of a summer of unrest and by flying empty sectors they won't be recorded as cancellations! Try telling that to the 300 plus pax left behind!
