Prem Ex,
I think that your letter was very well worded and certainly more kind and diplomatic than many I am sure that have been written today. I do feel though that your system would complicate things altogether as pointed out by the last post..."what happens if the upgrade does not clear?" I agree that the 1k lounges were ridiculous, the lounges themselves were typically dingy and small and as such I always used the RCC instead. I agree as well that if upgrade prices need to be raised than so be it. I must stop short there however as it would be completely archaic to try and figure out which of the non-refund fares are upgradeable under your plan. Nice letter though, I am sure it will be circulated and considered
