I was checking airfare from AUS to HNL and IAH to HNL about a week ago for business travel (21 day advanced purchase). The flights were costing $1100.00 roundtrip (not unusual) I received an email last night from United for Hawaii Flight Sales. They were offering one way flights for the above cities for $569.00 each way or $1138.00 round trip. Not much of a savings. These so called savings included 14 day purchase and ends October 18.
