If UAL's fare structure prices a round trip seat from/to CLT/HNL at $700, please explain to me why it's OK and doesn't circumvent UAL's fare structure for this route to be pieced together CLT-ORD-LAX and LAX-HNL for $200 less as ckidder331 describes!

And I would bet if the straight CLT/HNL destination were plugged into standard fare software the very same itinerary might very well be spit out at $700 instead of $500.

This is why I first raised the question of fare circumvention. Whatever the "trick" and whatever the "name," if you can put together an itinerary from/to A/B at a lower fare than a major's published fare I believe you have circumvented its fare structure. And if this be the case, then at least on CO [and I HAVEN'T seen it on any other carrier YET] you have committed an act which subjects ALL of your accumulated OnePass miles to forfeiture.

Again the question isn't whether you can "get away with it" but rather, whether you have stopped playing by the rules. As the internet gets more sophisticated I fear airline software is going to be able to begin ferreting out circumventions such as these. When that happens I can already see automatic back charging to our credit cards of the fare differences and deducts from our FFM accounts.

Think about it...

BTW, I love all the names; "nested tickets," "hidden cities," "back-to-backs," "point-beyonds," "throwaways." How about a double mocha cappacino with a twist on the rocks?
