Wish I’d found this guide earlier!
Frustratingly bad experience Global Explorer with QF for ticket changes after booking direct via oneworld website after BA kept on failing to price via their back office. Wish I’d persevered as Qantas customer service / IT is non-existent / terrible. QF agents just don’t understand these fares and getting changes made seems to be a constant battle with their IT systems.
