This is the first week since the end of October that we’ve had a full compliment of airlines offering Internet specials. In fact, this week and next are two of the best value travel weeks of the year!

If you can get away from your holiday preparations, be sure to take advantage of one of these specials.

Many of the largest airlines in the United States offer weekly, online-only fares, perfect for quick weekend getaways.

For travel novices, these Internet deals are last-minute airfare specials offered each Tuesday for travel on the upcoming weekend. Most fares are non-refundable and must be purchased immediately, but these specials often represent significant savings over advance purchase fares.
