About Miles Calculator

Updated 27 September 2026

Miles Calculator is an independently run website for people who want to know what a flight is really worth: how far it goes, how many miles it earns and how much closer it gets them to airline status.

What the site does

The distance calculator works out the flying distance between any two of about 3,200 airports with scheduled flights, including multi-stop and return trips.

The status calculator takes that route, your frequent flyer programme, your current tier and the fare you booked. It shows the miles or points you'd earn and how far the trip takes you towards keeping your tier or reaching the next one. It covers 37 programmes across Star Alliance, oneworld, SkyTeam and independent airlines.

The guides explain the rules behind the numbers, such as how to find your fare class before you book.

How the numbers are worked out

Distances are great-circle distances, the shortest path between two points on the Earth's surface, calculated on the same ellipsoid model of the Earth used in aviation and GPS.

Earning and status figures follow each programme's published rules: earning tables by booking class, fare type or spend, tier bonuses, and the targets for reaching and keeping each tier. Where a programme only publishes figures through its own calculator, the site asks you to enter that figure rather than guessing.

Always check with your airline. Programmes change their rules often and sometimes without notice. Airlines also use their own distance tables, so their figures can differ slightly from ours. Treat the results as a well-informed estimate, and confirm anything important with the programme before you book.

Independence

This site isn't affiliated with, endorsed by or paid by any airline, alliance or loyalty programme. Airline and programme names belong to their owners and are used only to identify them.

The site is free to use and is paid for by advertising. Advertisers have no say in the content, and no programme can pay to be ranked or described more favourably.

Found a mistake?

With 37 programmes and rules that change all the time, corrections are genuinely welcome. If a figure doesn't match what your airline says, please let us know.
