I applaud your decision to not renew GGL and to fly away from BA and (presumably) Oneworld moving forward. The more people who do so will result loss of market share and passenger numbers and perhaps a better passenger experience for all moving forward. In the meantime I hope whoever gets your business moving forward lives up to expectation. I fear however that unless your airline of choice is Harrods Aviation and using private terminals or equivalent you're going to end up disappointed again rather quickly.
