In the same week that Europe's Lastminute.com was acquired by Travelocity owner Sabre, a new U.K. company - Allcheckin - has launched a price-comparison site for flights, hotel and car-hire information, writes NetImperative. Allcheckin, aimed at leisure and business travelers, searches across conventional sites to offer up its results. Earlier in the week, travel search service SideStep launched one-click shopping for travel packages, including flights and hotels, reports Internet News. The package search service launched with partners Vacation Outlet, Pleasant Holidays and Orbitz, and SideStep plans to add more soon. SideStep handles custom integration with partners' databases of destinations, flights and hotel fares.
