Today I booked my flight to LA for the West Coast PR Weekend in March! Check out the Fashion District's website – it looks like a fun place to visit with fellow seamstresses.
I used Farecast to monitor the airfare - today it dropped so I bought. You can create a free account and a "farewatch" in which you tell it your destination and the dates and it'll send you daily emails of the current fares, as well as a prediction of whether the lowest price will rise, hold steady, or fall. This is the first time I've used this service so I can't attest to how good its predictive power is. At a minimum though, it's certainly nice to have someone else doing the obsessive searches and comparisons every day for you.
I look forward to meeting some of you in March!
