I'm trying to book HKT-DFW or HKT-AUS on the AA website. They present me with a calendar of dates and prices, then when I select the lowest prices for the round trip, inevitably I get the "choose a different flight or fare" message except on the most expensive flights. The fare prices keep fluctuating on the lowest price, so I'm wondering if this error goes away at some point if they are indeed adjusting prices, or if this is just a bait and switch showing lower priced fares but not actually having them. This is quite frustrating to say the least. Thanks
