are you a student? have you looked into seeing if there are any special student fares?
it really depends on the time of the year that you go...i know when i went to japan last time, i went in december right after finals, and flew roundtrip for $600...

when i tried the same trip in the summer, it was over $1k.

 

Hey guys, thanks for all the insight and advice!!

Unfortunately, I will not be going to Korea this year so I don't need to look for a ticket anymore. Thanks again!
