(Sherman's Travel)These days, serving time in airport limbo is an expected part of travel. Vino Valo, a wine bar and retail chain popping up in airports around the country, is ameliorating the experience glass by glass. Debuting at Dulles International in 2005, it has since opened outposts in Seattle, Baltimore, Sacramento and New York. Up to 10 more locations are planned for 2008. Wine comes by the glass, bottle, or location-appropriate flight ('Sierra Reds" in Sacramento). Volos are post-security, so customers can bring their favorite bottles on the plane (from $4; vinovolo.com). -BB.
