Another cautionary tale regarding booking directly through the OW RTW tool... My first booking was ticketed by Qantas (despite having no QF legs in there, and not even going near Australia). Now I'm a victim of their data breach, and their call centers are totally flooded following the incident. It's now an estimated 3 hour hold time.
I'm trying to reach out by email to their Europe based local desks in the hope they can make date changes for me.
Wish I'd read this thread's advice before booking that first time. Sigh.
