I was invited to go to Hawaii (OGG) the first week of November. In playing with fares I found it to be generally $570 out of LAX. I live in Orange County, CA and LAX is very easy to get to. However just to play the devil's advocate, I plugged SAN in to see what would happen. It puts you on an Eagle flight from SAN-LAX naturally, then the same flight out of LAX to OGG, but the round-trip price drops from $570 to $449. The same happens with HNL. The starting fare LAX-HNL is lower at $489 but the new price from SAN is $449. With PLT and the minimum miles plus bonus I'd get 2000 RDM total for those short hops, save enough money to do a day of diving in Hawaii AND pay for the gas I'd burn driving to San Diego. It's a little pricey for a MR at 8cpm (and I'm 38000 miles short of EXP, so no point in trying as my travel budget is about $3k for the rest of the year) but almost impossible to resist flying that extra segment based on the lower pricing. Better yet I work for Amtrak so I could get to SAN for free if the times worked out. Anyway, what is the logic behind this... and is anyone else aware of similar situations involving these short hops where you are "paid" to fly an extra leg?
