Have priced up on itamatrix: ICN-LHR-GIG-SCL // SCL-IPC // IPC-PPT // PPT-NRT for $1,239
Got 20+ hour stopovers in London and Rio too. It prices up exactly on priceline but then it gets stuck - can't click on the "continue for $1238.50/person" button. I can price it up on AA's European website for $150 extra. Any ideas?
