Looking for some early advice, 2 pax traveling in early 2021. Trying to decide if I should try and get this as a (now) 318k ticket, or if it's likely to be all too hard and go for a DONE4/5 or point-to-point tickets. Basic required stops are South America (going to Antarctica), across to Africa (will probably do some Intrepid tour), up to Europe (skiing), across to Canada (visiting friends in Toronto) and back.
syd-scl-gru-jnb-lhr-yyz-lax-syd is a basic trip that appears to work, with plenty of miles up my sleeve (32,157). BUT the SYD-SCL and GRU-JNB might be hard to find availability for 2, since they are relative monopolies. Taxes will probably be scary too given JNB-LHR is BA (though I can do via DOH on QR and still easily come under miles). I'll do short hops on LCCs or similar (not wasting valuable stops on intra-Europe horrid seats!).
Appreciate any advice; I'm QFF gold for what it's worth regarding availability. Dates will be pretty flexible (am planning on taking close to 4 months).
