UA: YYZ to PEK $2318 CAD $1712 USD
I've been working on building this itinerary for about one week now. Finally successful in routing YYZ-ORD-SEA-DFW-PEK-DFW-SEA-LAX-YYZ which is 22,547 miles. Possible cities for routing are FLL/MIA, LAX, NYC and SEA for stops under 24 hours and the leg to/from PEK must be via DFW or ORD. My plan is to visit family on the SEA layovers of 22 hours in each direction.
My flight was booked using AMEX points which priced out at $1,910.42 USD. AMEX Travel bookings are very difficult using multi city routing as you may know. I could only get the first leg in economy (Embraer RJ145) and the other seven legs in business/first. Planning to credit to AS for 33,000 + EQM.
The basic
YYZ-ORD-PEK-DFW-YYZ routing is 15,185 miles at $1762. USD
