Can I change dollars to Korean won at Incheon Airport Bank?

pu1. Dollar->won-won->Dollars are both possible. It's because the commission is expensive

OK

pu2. It's better to just change it at the local bank. Airport banks are really expensive

OK

pu3. If you don't have too much dollar left, I recommend you spend it all abroad. The fee is really high for double currency exchange. If you change it at Incheon Airport, it's stronger
