It will also show you the fare basis - there is a code in their near the end that specifies its a BE fare - I forget what it is but there are others on here who can probably point out what to look for there. ....
OP is flying international (ORD-HND), so this domestic info does not apply
XK at the end of the fare class does signify
NON-REFUNDABLE. CHANGES NOT PERMITTED
