Ever-cool Virgin America launched their “Treats not Trick” sale yesterday, offering frighteningly low fares between Washington or Boston, or New York, and San Francisco and Los Angeles. Fort Lauderdale has been added to the mix, as well. I thought nothing of the sale, being discussed here, on FlyerTalk, until United and American did the classic fare match dance, and lowered their fares on these routes, as well.

As a study break, I poked around and was happy to report there are still many fares and routes available, especially on United. For a transcon, you’re looking at about 150, all in, for flights between JFK, SFO, or LAX, with Boston and Washington, Dulles working as well! The deal only appears valid on October 30, 31, and November 1, and allows one to get creative with routings. For flights out west, there exist a myriad of options, including leaving from both La Guardia and JFK, and returning the same day, the next day, or redeyeing back. One can even depart from JFK and return to Dulles or Boston. Look around for the best options, but hurry. Availability may be dwindling. According to the FlyerTalk thread, there are still some same-day transcon turns on American available. Try playing with the “Search Alternate Cities” feature on United.com, the multicity booking feature, and trying a number of days. You must book, at least for Virgin America, by midnight, October 29th, 2009.

A wonderful option for a quick trip, or end o’ the year mileage run (remember – it is the second double elite qualifying [DEQM] promo of the year).

I may just have to grab one at some point . . . there’s nothing like heading to Boston on Saturday from New York, via San Francisco
