If you fly a lot, check out Priority Pass. For anywhere from $99/year plus $27 per visit to $399 for unlimited visits, you can get into a ton of VIP airport lounges around the world. Skydiving PR man Peter Shankman Twitters "Priority Pass = Greatest. Thing. Ever. Flying CO but allowed full access into UA club. Vodka, wifi, comfy chair. YAY PRIORITY PASS!" The list of lounges (PDF) includes most major airports, including SFO. Even if you're grounded, you can flash the card at dinner just to impress, or more likely annoy, your friends.
