Enter flights in the sidebar, one per line. Each line is an origin-destination pair using ICAO codes (KJFK), IATA codes (JFK), or FAA identifiers (FFC).
Separate the pair with a dash, comma, space, or arrow:
JFK-LHR LAX NRT KJFK, EGLL SFO -> SIN
Upload a CSV or text file with two columns (origin and destination). The first row is treated as a header and skipped. Comma, tab, semicolon, and space delimiters are auto-detected.
Plot Flights (or Cmd/Ctrl+Enter) validates the codes and draws great-circle routes on the map.
