Those of you departing out of San Francisco International or San Jose International today, will notice that your baggage costs are on the house. The purple house, that is. Yahoo! is going to pay for it. That’s gonna cost a lot on one of the busiest travel days of the year, and not sure how you balance that expenditure with the fact there’s a worldwide Yahoo! shutdown from the 25th to the 1st, and if you want to be paid during that span, you have to use vacation time. Search Engine Land says this promotion is part of the Yahoo! For Good inititive, yet there’s no mention of this on that site or the corporate blog.
