I'm thrilled to see I'm not the only one who keeps track of such useless information. I don't have a breakdown of the different airlines (althought that's a good idea and you may have just given me a new little project to work on). My total with lots of business and 1st class tickets is about 585,000 miles for a savings of about $40,000 US. I travel mostly internationally so I get an enormous financial savings with what I think is a small amount of miles.
