Traveling by air is considered the safest but doesn't seem to be the most sanitary way to do so. This just did not make sense in any way subjecting passengers to seven hours of unsanitary conditions. People deserve to be treated with dignity whether or not they complain about poor service. 

That plane should not have taken off without the situation completely resolved during that first incident. They should have explained situations, ensuring that matters were resolved including educating passengers and or possibly an alternative flight arranged for passengers for the purpose of health and time constraints. That is totally embarrassing to here reports like this regarding an American flight, or for that matter any Airline.
