How Can I Check Air Mileage From One Country To Another?

You could check with the airline that issued you the ticket about the distance the aero plane will be covering. There are a number of websites that provide distance calculators between two different places. You can use www.geobytes.com or www.infoplease.comatlas/calculate-distance.html. The distances that these sites provide are "as the crow flies" or in a straight line. They do not necessarily reflect distances on the ground or those covered by aircrafts as even planes may not necessarily fly straight. Planes may at times circumvent and avoid flying over conflict zones. Aircrafts may also spend time circling in the air before landing and this does not reflect actual distance.

While using these engines to search for the distance between two places that you may have to detail your search as several places the world over have the same names.
