Sept. 19 — US Airways announced at about Noon Tuesday it is offering special sale fares throughout its system for two days only. Roundtrip prices start as low as $179 for Caribbean travel – but it may not include OUR Caribbean. An initial search of fares found no discount to St. Thomas midweek from LaGuardia or Washington National – tickets about $450. (I did find a deal for about $200 from Nashville!) Special fare offerings are for Monday-Thursday, and travel must be completed by Dec. 16. Purchase tickets no later than Wednesday.
