I find this point of view utterly mystifying. Making sure you don't miss your flight only costs a couple of hours, and the effort of being organised enough to leave on time. Missing the flight has a cost of lots of money, many more hours, and a whole bunch more organisation and talking to people. It seems like a dead simple trade-off. Sure, if you end up missing the flight because of unforeseen circumstances, and you can afford to burn a few hundred bucks without it affecting your budget, there's no sense in feeling particularly bad about it. But I see no sense in deliberately putting oneself at risk of that situation, unless your time really is that valuable or you have a massive aversion to being organised that outweighs the rest. (I don't count 'having ADHD or otherwise being a very disorganized person' as 'deliberate', for what it's worth: if that's the case then maybe adopting the viewpoint above really is a good idea?) [edit] Ah, noticed further down that you were taking domestic flights where rebooking cost you around $100, where presumably that's in the range that it doesn't hurt you too much to spend. You should probably note that everybody you're responding to has had to pay way more for their rebookings, so really you're looking at a completely different trade-off from them.
