EVA Airlines (BR) is not Sky Team, but is a CO partner. All EVE flights will get you CO mile points, but for EQMs you need to get a CO codeshare (I think, I live in ATL so obviously don't fly CO )

The RT Biz fares are from about $1800 from the west cost (LAX/SFO/SEA). But you can chose an executive economy (called Evergreen Deluxe) that will run about $1000, seats are much more flyable than coach across the Pacific. [They have some kind of funky 2-tier pricing scheam that will try and sell you inventory over 50% more expensive, don't fall for it]
