I never feel like I’m getting a good price when I buy airplane tickets. Do I buy through an agent? Do I buy through the airline’s website? Do I get them six months in advance or six weeks? Whenever I finally click the purchase button I know that there’s some secret handshake or coupon or magical elf that could have gotten me a better deal. Maybe I just need to learn to only be interested in things that are within walking distance of my house.
