About
Ask about an airport, a country or a month and it answers with: It can also build a search link with the traveller's dates, drivers and card type already filled in; the link opens live prices on carrentalbrain.com, ranked by the total actually paid, where the traveller books with DiscoverCars. The figures are measured aggregates, not live quotes - every answer says how many searches it rests on and when they ran. Read-only, no account, nothing personal requested. Car Rental Brain earns a commission if a booking is made through its links; the traveller pays the same price. Limitations: measured aggregates for the airports listed by list_airports, not live availability; prices mostly in EUR.
