Virgin America ... is studying whether to fly to Dallas/Fort Worth Airport, Austin and Atlanta, CEO David Cush said Tuesday.

... "We have analyzed Dallas and Austin, places with big corporate and technology bases that certainly would have some synergies with San Francisco and Los Angeles," which the airline already serves.

Toronto and Vancouver are also being studied as possible destinations...

... Chicago, where rivals have so far refused to cede gates, remains at the top of Virgin America’s expansion choices, Cush said.
