Airline Mileage Calculator

MileCalc is a powerful airline mileage calculator for frequent flyers. It is easy to use: Quickly add airport codes, then calculate the total itinerary mileage. Itineraries can include an unlimited number of airports.

In addition to basic flight distances, the calculator supports elite-level, booking class, and promotion bonus miles. MileCalc includes preset options for major US-based airlines (American Airlines, Delta, United, US Airways), but is flexible enough to support most other carriers.

Operation is 100% offline (no hefty data charges!), so the calculator works anywhere, including those long flights! And yes, our airport database is comprehensive.

Distance calculations rely on the advanced "great circle distance", the measure used by most airlines.

MileCalc is inspired by the popular site MileCalc.com, The Ultimate Mileage Calculator for Frequent Flyers.
