hey. thanks for the answer.

a RTW starting in warsaw and ending in warsaw is WAY cheaper than one starting in NYC and ending in NYC. did it today on the star alliance RTW tool.

im still confused by your answer, so let me give you my examples.

my choice is

Option 1: NYC-WAW-India-Thailand-Hong Kong-Singapore-Australia-Fiji-NYC

or

Option 2: WAW-India-Thailand-Hong Kong-Singapore-Australia-Fiji-NYC-WAW

Note: I already have a ticket that I booked earlier for NYC-WAW-NYC, to get my NYC-WAW leg for option two, and am ok losing the WAW-NYC return.

so my question is, if i were to buy option 2 and then when I arrive in NYC decide that I just wont be taking the last flight of my RTW ticket, will Star Alliance charge me anything for canceling that last leg? I have zero experience in this, but I could imagine two outcomes

1. no charge at all, i didnt fly, end of story, RTW ticket completed
2. Star Alliance going back and charging me extra for all of my prior flights as my RTW wasnt completed in full as book and i didnt back to the same country of origin (i.e., i didnt physically start and end in that country, obviously i would pay for the whole RTW ticket)

thanks!!
