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.

OpenFlights

Airport and airline reference data — the names, cities and timezones behind every airport code, and the airlines behind every flight number prefix.

OpenStreetMap

Maps and place search. Map data © OpenStreetMap contributors.

OSRM

Driving routes and distances between the stops on a day.

Frankfurter

Exchange rates, so a trip's costs can be read in one currency.
