It's similar in principle to the site I've been using for quite a while as an airfare meta-search engine, Mobissimo. (http:// www.mobissimo.com). The Dohop interface seems clunkier, at least in my browser (Firefox). Plus there are some annoyances, like quoting a flight from a non-Eurozone origin to a non-Eurozone destination in Euros. (SFO-LHR on UA). Mobissimo also claims to search 139 sites, and seems to include all sorts of airlines including the LCCs, plus it normalizes fare quotes to USD (great for Americans, dunno if there are options for displaying in other currencies). So for now I'll stick with Mobissimo, which I usually don't bother with for domestic travel, but it saved me a bunch of money on a flight from London to Zurich last year by finding a cheap flight on an airline I hadn't previously heard of (Helvetic). -- Michael C.
