Buying UA Z-fares when they show up? Z is sometimes cheaper than B, and saves you the miles to boot too. Of course, 50-day advance purchase and tight availability count against me, but upgrades to J are capacity controlled too. And there's no risk of losing an upgrade due to equipment change; Z is paid business class.
Sample: SEA-FRA on UA
ZSPECE: $3202.00
BEE: $3675.00
Honestly, if you want consistent (near 100%) upgrades, you buy the class you want, or have some checking of inventory before you begin booking. The SWU/miles from discount economy route is not bad. Expensive on the miles, but miles are comparatively cheap to dollars.
