Saving for Act III Tour

I am already thinking ahead because I will not be able to attend her tour this year and I want to start saving for her next tour probably in 2/3(?) years. It is especially difficult for me to secure tickets as someone coming from Asia, East and Southeast Asia to be specific. Hopefully, my school calendar will go along with the future dates. ~

Is there someone from the same part of the world who has experience going to her recent tours to the US and EU? I just want to know an overall guide on the realistic expenses that I must prepare for to attend her show for the first time.

Thank youu! ㅠ
