If your daughter hasn't already booked, if she is in education,student,graduate ect or can pass as one some travel agents
do flight packages for backpackers, gap year students ect really cheap. A few years ago my eldest daughter booked a series
of flights over a 12 month span. UK =Singapore=Indonesia=Oz=NZ=Oz=USA=UK and it was silly money, really cheap.and she
changed her plans to stay in OZ longer with no problems.
