I'm seriously considering doing my trip in reverse. The more I think about it, the more comfortable I am with the idea.
Checked out some flights today. Found a great deal from Shannon to NYK for €118. Then NYK to Lima is working out at about €360. Santiago to Auckland is an eye-watering €1200, didnt check flights to Oz...but then Melbourne to KL was about €400.
After that, the bulk of the fligths would be out of the way, apart from a my flight home at the end of the trip. Working in NZ for the year would also allow me to gather some more funds for the SE Asia leg.
Honestly, I'm very daunted at the prospect of India as the first stop on the trip. I think leaving this until the end is wiser for a few reasons. Firstly, I will be a savvy traveller by the time I get there and it will probably not seem daunting at all. Secondly, what a great place to end a RTW trip Thirdly, I'll be getting the more expensive half of the trip out of the way first, and wont need as much money for the second half.
I'll probably have changed my mind again by this time next week. Lol!
