There is a promotion for 5,000 bonus miles for a 'roundtrip' from the 48 continuous states to destinations in Hawaii.
I am planning a trip SFO-LIH-KOA-SFO, with the segments in and out of SFO on UA and the LIH-KOA segment on Aloha. Will United consider this a 'roundtrip' from SFO to Hawaii and award the bonus?
