I'm new to booking with rewards miles so I thought I'd consult the experts! I'm trying to book a trip for two from LAX to TPE and ICN next march sometime and I'd like to fly in business. I have about 100k miles (Chase Sapphire ftw!) so is it possible for me to book 2x Coach-Business upgrades (100k miles) on a LAX -> TPE round trip award with a 6 or 7 night stopover in ICN? Is this routing even possible or is it wishful thinking? Would an "open jaw" round trip work better? I've been trying to learn how to actually use my miles so any resources would help as well! THANKS!!
