I have bought an LGLOB34 mainly so as to be able to fly on i) QF's former codeshares within NZ on Origin Pacific and ii) QF's codeshare on TN for AKL-PPT. Routing was (IIRC)

SYD-xCHC-ZQN-xCHC-xAKL-PPT-IPC-xSCL-JFK;PVD-xORD-STL-BOS-xLHR-PRG;EDI-xMAN-HEL-xBKK-xMEL-CBR

I bought it not to maximize mileage but because at that time the LGLOB34 bought in Australia was cheaper than a simple SYD-BOS roundtrip. Since I wanted to go to PPT and IPC, it was therefore either a LONE5 or an LGLOB34 for this trip. The LONE5 was a more expensive option for what I needed; one-way AKL-PPT fares are expensive and I didn't have miles to do an award trip at that stage. The ticket let me make all the side trips I wanted for the next few months (all I had time for), so it was the best option for me.
