It’s a good week for airfare specials, particularly the Delta Airlines fares to the Caribbean. 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. Most fares are non-refundable and must be purchased immediately, but these specials often represent significant savings even over the advance purchase fares. Below is a recap of this week's offerings.
