However, I am looking at DFW- BKK in January and it seems availability is a moving target. Seats are limited to a handful of dates in January. But every other day I look at the options in January and they are different. I'm guessing this is because these flights have at least one leg operated by a partner? And I'm guessing that availability of seats with their partners is the factor in play. Can someone explain what I need to be looking for, other than to book ASAP? Can I expect inventory in the AAdvantage program to open up as a date comes closer? Or is this going to be unpredictable. Thanks for your input.
