If you’re looking for a quick weekend away, this is a good week to go. This week’s Internet specials span the United States, from the east coast to Florida to the California coast. For those unfamiliar with these offers: a number of US airlines offer last-minute airfare specials beginning on Tuesdays for travel on the upcoming weekend, including this weekend.
