If you're traveling through Boston's Logan Airport (BOS) or Seattle-Tacoma Airport (SEA) today, you have the chance to be one of 1,000 lucky people randomly selected to get a MasterCard cash gift card worth $15. That's the price of checking luggage on some airlines.
Bing is doing these random-acts-of-publicity the day before you stuff your face full of sweet potatoes and marshmallows.
Why Boston Logan and Seattle-Tacoma? These are the two airports that were used to launch the original Price Predictor.
Good luck, and safe travels to you.
