Although since the late 1980's I've earned the better part of 3 million miles I've never spent more than 35K miles on any one award as all of my redemptions are for coach "saver" type free roundtrips either within the 48 states (typically 25K miles) or to/from Hawaii (35K miles). As soon as my balances reach these mileage thresholds I typically make an immediate redemption to zero out the account.

PS: Not one single mile of my 3 million has been used for an upgrade - I know some FTers cringe at the thought of the indignity of having to sit in the back of the bus but burning miles for upgrades is a total waste in my book
