I am planning to burn my miles for a family trip. Here is what I am thinking:
- Leaving from YYZ (Toronto, Canada)
- Stopping over in AMM (Amman, Jordan)
- Destination is RGN (Yangon, Myanmar)
- Open jaw to HAN (Hanol, Vietnam)

Is this a valid routing?
YYZ->FRA->AMM(stopover)->IST->SIN->RGN // HON->TPE->YYZ

Alternatively, I may stop at Aqaba (AQJ) instead. IST is the only city with direct flight to Aqaba. Can I book the below route? Or is this considered backtracking?
YYZ->FRA->IST->AQJ(stopover)->IST->SIN->RGN // HON->TPE->YYZ

I really appreciate any help you can provide.
