Now doubt that travel search is one of the hottest vertical search markets out there. Today, Mobissimo, a travel meta search site that brings together results from many travel databases and sites (137 to be precise), has released a new feature (it was officially announced today) that allows the searcher to enter a query in a natural language format in what Mobissimo calls a One-Box search.
In other words, no more filling out from/to boxes, entering dates, etc. Just type in a query like Chicago O'Hare to Honolulu, February 1-15 (sounds nice, doesn't it) and away you go. If further info is needed you'll be prompted to clarify the info. Btw, One-Box search only works for air travel at this point. It's a neat idea and one that I wouldn't be surprised if we this concept elsewhere in the future. More about One Box Search in this Mobissimo blog posting. Btw, the "traditional methods" of searching Mobissimo are still available.
Postscript: The Mobissimo One-Box kind of reminds me of a feature that MSN Maps has offered for over a year. It's called "Paste an Address" and allows you to simply copy and paste a location into the search box and have it format automatically. No more filling out a form. It's available for 20 countries or cities.
