So after being in an airplane for 4 hours and then getting off at the same place where I entered, I began asking the untied associates what happened. The usual line of excuses... Then I began asking other individuals in the industry for insight on why this has happened 3 times this summer, I mean are the using 386 as their computer system? Well as it turns out, United and American have overbooked many of their flights 3 fold to make sure that they have enough people on the flight... This has created a backlog and if one small issue arises then suddenly that hiccup cascades into a major issue for everyone involved! Sad to say, but subsidising crappy companies leads to crappiness of unheard of levels. If an airline is mismanaged don't give them money to perpetuate the problem, let them fail. Then another company will fill that gap. Socialism in a capitalist soceity doesn't work.
