I USED to think that I had earned alot of miles until I read this thread, anyway I've earned approx 2.5M to 3M miles, less than 5%of which were paid for by my employer.
To each his own I guess, but when I think of using 2M miles for one RTW award (even if it was for 4 people) I cringe. I have used a grand total of zero of my miles for upgrades as I think 1st and Business Class travel is GROSSLY OVERRATED - I think alot of it is just an ego thing because it makes the front-enders feel "special". I was a UAL 1K for a couple years and have flown many times in upgraded status (at least 20 times on the ORD-HNL nonstops alone - all using complimentary upgrade certs and never using miles) and I admit it was nicer than sitting in the back of the bus but definitely not worth spending extra money or using miles. I look at 2M miles as being the exact same thing as $40K in cold hard US cash and personally I couldn't justify spending that much on one award. Just one man's opinion...
