code shares across SkyTeam carriers
The situation: I need a roundtrip from SFO to SCL (Santiago, Chile). I want to buy a coach ticket and upgrade with miles. I'm CO Gold Elite.
The choices: The best option seems to be a Delta flight from SFO -> ATL -> SCL. It's code-shared with Northwest and Continental and NW's prices seem to be the lowest. CO's price is 2x NW's price on the same exact flights. Go figure.
Stupid/naive questions:
- How do I actually book a flight with NW and get CO miles for it? Is there some way to do it online from nwa.com? Third-party like Orbitz?
- NW's web site says "select coach fares" cost 20K miles to upgrade one way while others are 10K miles. Which gets what?
- Any other advice/gotchas about how to properly make this reservation?

You can't upgrade the ATL-SCL flight on DL metal with CO miles, even though it is a CO codeshare. I'm pretty sure that the same holds for NW, but not 100% certain. Any fare other than full Y costs the 2x miles to upgrade; only Y fares are the 1x rate.
If you book the flight on nwa.com you have the option to add your CO OnePass number during the booking process; that part is pretty seamless.
If you actually want to be able to upgrade all the way to SCL you'll need to fly on Copa via PTY. You can connect in LAX or IAH and then on to PTY then SCL. Of course, the PTY-SCL flight is on a 73G with domestic F type seats/service, not the DL BusinessElite service/seat.
