Hannibal, Thanks to you for sharing your insight and to others that have posted about booking RTW.
In about a month (as some availability hopefully opens up) I will be trying to book ANA RTW for three of us(family) in business class. Trip is in March of 2019 and will include SIN as we have a cruise departing from there. We will also be doing a multi day visit to MUC and one in Japan(Tokyo). ORD is basically our home base but we might have a different start or end to hit the under 20,000 miles level on the RTW award chart.
My biggest concern is finding flights that have three business class seats available. We might have to make some "tough" choices of either our teenager traveling in economy or one of us flying a separate date/flights for some legs. The good news is that except for cruise departure and return dates we are flexible on when we can fly and even what direction to make the trip.
