This can only be done with TATL or TPAC fares, for North American fares a non refundable fare can only be applied towards another wholly non refundable fare, or a partially non refundable fare where the new non refundable portion is equal to or higher than the original non refundable fare.


As to non ref first fares to HI, try going into OGG most markets that had them to HNL now just have them to OGG
