Hello,

I have an upcoming business trip that will require me to make a round the world routing. Our travel agent here at work currently has recognized it will be a round the world routing but plans on issuing 3 separate tickets (Qatar, Cathay and Air Canada).

I would like to have it all booked with OW carriers to maximize my tier points and also to "sell" it to our travel agent as hopefully being a cheaper option than what they are currently quoting (which is about CHF 8400 in business).

The basics of the routing are:

GVA-HAN (currently booked as via DOH on QR which is fine)
HAN-SYD (currently booked as via HKG on CX, also fine)
SYD-YYC (currently booked via YVR on AC which is the problem)
YYC-YTO (currently on AC, also a problem)
YTO-GVA (currently on AC, also a problem)

I've seen some of the more desirable routings getting me from SYD-YYC on OW carriers are:
Via SFO on QF then WS - the BA Avios flight calculator indicates I get neither tier points nor Avios for the WestJet segment from SFO-YYC
Via SFO and SEA on QF then AS for the last two segments - I believe this would get me Avios only for the Alaskan Airlines segments
Via NRT and YVR on JL then WS - flight routing here is 3.5 hours longer but I would get 280 tier points for the two long haul Japan Airlines flights, then nothing on the WestJet flight

Any recommendations on how I should play this with our travel agent? To be honest I am not even sure if they are eligible to purchase the OW RTW ticket for us. In any event, all suggestions on how I can maximize the benefit of this for my OW tier point balance gratefully received.
