go install github.com/asmarques/miles@latest

To calculate the distance for a given itinerary, specify the IATA code of each airport along the route as an argument to miles:

$ miles LIS EWR SFO EWR LIS
0: LIS	EWR	3384	miles
1: EWR	SFO	2565	miles
2: SFO	EWR	2565	miles
3: EWR	LIS	3384	miles

	total:	11899	miles

The miles command supports the following options:

• -d to specify the path to the airport database. If not supplied, the embedded airport database is used instead.
• -o choose the output format. Available formats are: text (default), json and kml.
• -v to enable verbose output when using the text output format. Includes additional airport information such as airport name, country, latitute and longitude.
