Hi,

I'm going to plan a trip from SFO-stopover-SYD(destination). This will be my first time redeeming miles and as well as flying business class internationally. I only have United Miles!

For the stopover location, Can I have it in Europe(CDG/BCN/MXP?) vs Asia(ICN/NRT/SIN?). I'm not sure how the stopover rules apply. I prefer to visit EU over Asia.

As for award redemption, I know it's cheaper with miles to fly on United metal, but it seems United partners(Lufthansa/Swiss/ANA/Asiana) will offer a better flight service(food and comfort). Which one will be more superior?

Does anyone have a routing or airline they would recommend? I don't think I saw any first class cabin available, but is it worth the extra miles to go in first class if it is available? Like I mentioned, flight food/service/comfort is most important.

Am I able to book a round trip ticket with awards where the outbound is in business/first and inbound is in economy?

Thank you flyertalk community!
