For those of you who are hell bent on driving a comparison between the Loco's and thLHR S/H operation don't seem to understand how the finances backing SH work.
SH has quietly turned a profit for a fair few years until this little spat.
That is when all LH connecting flight revenues for SH flights are attributed to the LH gained revenue. SH gains only a punitive (£10 springs to rusty memory) fee from each passenger. Yet despite this SH has turned profit.
So, whilst there is room for competition within the SH arena don't write off LHR SH just yet. Costs are under control, productivity (thanks Willie) is on the up and the recent ice has shown just how EJ and RYR can get caught as well.
