Hi everyone, I came here because Cathay is the only airline that would allow four/five stopovers. Any insight you can share on the following desired itinerary would be most appreciated.

Here's the desired routing: SIN-LHR, LHR-YYZ, YYZ-DSM, DSM-BHM, BHM-SFO, SFO-SIN.

I count four stopover cities: LHR, YYZ, DSM, BHM, and SFO with one of them being the "destination".

I have a little under 200k SPG points, and almost zero Citi points. Some UR points. I have some United points but that's a moot point because they don't allow that many stopovers, which is critical for this trip. How can I maximize my transfers to Asia Miles?

Also, which airline do you suggest I use to book this trip in a way that would minimize miles spent and have the lowest fuel surcharges?

Many thanks in advance!
