I got super lucky once and got to fly first class on points to east Asia via Asiana and ANA and holy shit the level of service is just out of this world. You get personal service from airport to airport, including an employee (or sometimes even more than one) escorting you from lounge to gate. The catering was among the best food I've ever had, and they turn down your seat and give you pajamas. In retrospect I'm especially impressed because I was a dumb twenty-something year old with no business being in a first class cabin.
