Yes, thanks for the link. Though it doesn't give prices, and the route calculator seems to not be working, the rules look good, and it is more convenient being a Star product, rather than just being limited to one of the individual carriers. I'll have to find out more about this.
As for the Jet Blue option, a couple of problems I see on that is:
1) One of my destinations is MSP; I don't believe they fly there, do they? If they are serving MSP now, it still wouldn't be too good, as my International arrivel is at LAX. Thus I'd have to fly a circuitous routing of LAX>JFK>MSP.
2) The Star North America Airpass links it's baggage allowances to your International flights. (Hey, isn't that smart!) As a *Gold with international legs in Business Class, I'll have an allowance of up to 3 pieces @ 70 pounds each. I would get that anyway as a Star Gold on CO and UA, but US normally has 50 pound limits, and this pass allows me to get 70 pounds on US also. Though I arrive with largely empty suitcases, I usually stock up when I head back out of the USA. The higher baggage limits help!
