You know what? Flying should be amazing, but it's really unpleasant. The air is stale and dry because it's cheaper to recycle it than purge and refresh mid-flight, and it can make you sick. The seats are cramped and so bad for you that they need to advertise special exercises to prevent them from killing you. The first solution we have for that is not better seats but airline anti-death seated yoga. We absolutely should be amazed at the prospect of flight, but I don't think the entirety of the problem is our jaded natures. Our worst seats at home are better than airline seats. If we were able to bring our own, we probably would. Doesn't that mean something has gone wrong?

PS - It certainly seems that way.
PPS - Most of it is probably because we're racing to the bottom to provide the cheapest flights.
