Every so often United Airlines tweets a link to a web page containing a special promotion code giving significant discounts to specific destinations. These secret TWitter fAREs, called TWAREs, are only available for a short time window, usually around two hours. So, if you see something good, you have to grab it fast. Last May my friends and I got half price TWARE tickets for a July trip from San
Francisco to Maui. Today, I scored a deeply discounted ticket from San Francisco to Sydney, Australia. You can get in on the TWARE action by joining twitter.com and then following @UnitedAirlines.
