I am new to AA but not to Expert Flyer. For my return HNL-DFW-DTW on May 31 I consistently saw 0 availability for every class on AA DFW-DTW, and 0 for most classes on HNL-DFW. This was the situation beginning at least 2 weeks before the flights. Also seemed to be the case for most AA flights on these routes. How do you interpret these data? AA verbally assured me the flights were not sold out
