BA's withdrawal of the Cork - London routes (specifically LHR) was in part down to their battle at the time with VIRGIN on the transatlantic routes, as part of their 'Dirty Tricks' campaign. To free up more slots in LHR, they simply pulled their ROI services thus ensuring they could get more aircraft in and out of Heathrow to compete with VIRGIN. Subsequent BA ROI services were provided by City Flyer out of LGW and LCY.
