I am a 1k and want to change date a k class ticket, they said it is $250 plus $25 service charge but then they said you are 1k so the $25 is waived, I was like since I am 1k cant you waive the $250 and I will pay the $25 for your time and effort, of course she was like no.

Any smart and ideas are welcome, I am in ICN, Seoul, Korea so dont think it is going to be easy.
the Ticket is a 90 day so a one time date change for free or very little would be great.
