We booked the most basic mini-RTW that you can expect for 3 people. Happy to find this itinerary for January. Like above, super speedy (under 20 minutes for 2 separate bookings as there was only one J seat on BKK-TPE - and HKT-BKK, but I assumed correctly that was opening after the first 2 tickets were ticketed.)
YYZ-IST (stop) TK
IST-HKT (destination) TK
HKT-BKK (stop) TH
BKK-TPE-IST BR
$106.86 per ticket plus $33.90 booking fee. This is only an 11 day trip, so we didn't throw in anything extra or special. We also didn't realize that there was a direct IST-HKT flight, so that was handy to find on the *A flight map.
