I'm a hoarder, and a selfish one at that. I'd rather buy friends and family a ticket (and do often, for certain work-challenged family members) than use my miles. I save them up until I have enough for 3 F tickets to some international longhaul destination, and then blow them all on a fabulous F experience with the wife & kid. Have done it for LAX-LIS, CLT-BKK and more. Next year: ZRH-JNB.
