Well put. Also, it's not like there's 1 single sky zeppelin that you won't see again for weeks. Admittedly, I'm a bad about deadlines and preparing. I traveled for work for years and missed several flights. Not fun, but as long as your actual schedule isn't too tight, it's usually no big deal. I talk to the airline, they put me on another flight later, I wait around a bit or go home and come back for the alternative flight.

At one point I lived like 15 minutes from a smaller airport. I could literally get there 30 minutes before departure if I overslept or something and usually made it through the quick security and onto my flight...
