Farheimr is built on other people's work. Here is whose.

AeroDataBox

Flight schedules — the scheduled departure and arrival times, terminals and aircraft shown when you look up a flight by its number.

adsbdb

Flight routes, letting a flight number alone resolve to the airports it flies between. The underlying route database is the work of David Taylor, Edinburgh, and Jim Mason, Glasgow.

Airport and airline reference data — the names, cities and timezones behind every airport code, and the airlines behind every flight number prefix. Airport data © OpenFlights contributors, available under the Open Database License; our extract of it is available on request at hello@farheimr.com.

OpenStreetMap

Maps and place search. Map data © OpenStreetMap contributors.

TomTom

Driving routes between the stops on a day and, when chosen, the map tiles. Roads and maps © TomTom and © OpenStreetMap contributors.

Frankfurter

Exchange rates, so a trip's costs can be read in one currency. The rates are published by the European Central Bank and other central banks.

Desert Ant Labs

Powered by Desert Ant Labs. Its Redact and Tongue models run on our own servers and hide personal details in mail to our team before any other model reads it.
