The bad news was that I had gotten my departure time wrong, the good news being that my departure time was actually 15 minutes later than I thought it was, so no problem.
The flight back was good with only about half the seats taken. I had my row entirely to myself, and the only people who had middle seats were those people who were actually sitting together.
Arrived, grabbed the luggage and took another taxi home (only $26.40 this time) and collapsed.
