Another problem is the airports. You've got check in, then security before you get anywhere near the boarding gate. If the security is being anal, then people are stuck in long cranky queues. At the other end, if it's an international flight, then you have immigration, customs queues etc. If any of them are being anal, again you have long queues, this time with cranky as well as tired people. So there is quite a lot to look at before air travel can become common place again.
