For the past few months, it seems that the "Gates & Times" feature on the main page at AA.com has been broken. It used to return a list of all flights between the requested city pairs on that day, from which you could then select the flight of interest. For some time, it seems that it more often than not says "No flights were found. Try expanding your search by selecting alternate dates, class of service, airports, number of stops or including more carriers." unless you enter the flight number.

Have other people noticed this?
