I'm sure that airlines must closely guard their FF numbers, but does anyone have an idea about the number of elite members on various airlines? This would encompass 1st-tier, Middle-tier and platinum, which seems to be what most programs have these days. I'm constantly amazed by the number of UA, AA, & US mid-level and above elites who struggle to get upgrades. I know that some of the cabins can be small, but I thought most airlines were expanding their F/C.
