For me the demo pulled up flights, but in USD, I'd need it to be localised to be useful.
Airlines also tend to present different prices for different locations/currencies so I doubt this would be as simple as a UI change (though that would still go a long way!).
Yes, the demo doesn't localize results. And Beta doesn't have currency support just yet but it's on the list.
Beyond the price differences, airlines also grant scoped 'ticketing authority' in jurisdictions (eg. can only sell these tickets in EU or US+Canada etc).
