Default coordinates use Chicago O'Hare and Jakarta Soekarno-Hatta. Replace them for another airport pair.
Chicago to Jakarta Distance Planning
Chicago and Jakarta sit on opposite sides of the world. A direct map line is useful, but it rarely matches a ticketed itinerary. Most trips need a connection. The connection airport changes flown miles, travel time, and eligible mileage. This calculator begins with airport coordinates. It then estimates the shortest surface route across Earth. The result gives a consistent baseline before you compare flight options.
Chicago O'Hare and Jakarta Soekarno-Hatta are loaded as starting points. You can replace either airport name or coordinate. This helps when a trip starts at Midway, ends at Halim, or includes another nearby airport. The distance result is geographic. It does not claim that a nonstop flight operates. Use your reservation to confirm the actual sectors before expecting final mileage credit.
Formula Used
The distance calculation uses the Haversine formula. It measures the shortest path over a sphere. Latitude and longitude become radians first. The formula finds the angle between both airports. That angle is multiplied by Earth's radius in miles.
c = 2 × atan2(√a, √(1 − a))
distance = 3958.7613 × c
estimated flown miles = distance × routing factor × trip multiplier
estimated ANA miles = mileage basis × accrual rate
Premium Points estimate = mileage basis × accrual rate × route ratio + boarding points
The routing factor accounts for indirect travel. A factor of 1.00 keeps the great-circle distance. A higher factor adds distance for routing through another city. The ticketed mileage override is stronger than the estimate. Enter published sector mileage when you have it. The calculator uses that figure as the earning basis. This produces a more relevant personal estimate.
How to Use This Calculator
Start with the airport names and coordinates. Select one way or round trip. Add a routing factor for your expected connection pattern. Leave the mileage override at zero when you only need a distance estimate. Enter a published base mileage when ANA or your operating carrier provides it. Then enter the accrual rate tied to your booking class.
Use the Premium Points fields only when you want a planning estimate. Add the route ratio and boarding points that apply to your itinerary. Enter an average speed and layover values for a total travel-time estimate. The carbon field is optional planning data. It is not an airline calculation. Press the calculation button. Your result appears above the form. Export it as CSV or PDF for later comparison.
Example Planning Data
| Planning item | Sample value | Why it matters |
|---|---|---|
| Trip type | Round trip | Doubles flight distance and sector-based inputs. |
| Routing factor | 1.08 | Allows extra distance for a connection. |
| Accrual rate | 100% | Applies your eligible booking-class rate. |
| Layover | 2 hours | Adds connection time to the estimate. |
Use Estimates Carefully
Mileage credit is not guaranteed by map distance. Ticketed point mileage may differ. Codeshare flights may follow different rules. Partner eligibility may also change. Fare class matters. Operating carrier matters. Some tickets do not earn mileage. Always check the current ANA Mileage Club rules and the exact fare conditions. Treat this page as a transparent planning tool, not a booking confirmation. Use it before booking decisions.
Frequently Asked Questions
How far is Chicago from Jakarta?
The result depends on the chosen airports. The default uses O'Hare and Soekarno-Hatta coordinates. The calculator uses a great-circle measurement, then shows an optional routed estimate.
Does this page show an ANA award price?
No. It estimates miles earned and planning values. Award requirements can depend on itinerary, cabin, season, availability, airline rules, and current program terms.
Why is flown distance higher than map distance?
Commercial flights follow real routes. Connections, airspace, winds, schedules, and airport choices can add distance. Use the routing factor to model that difference.
What ANA accrual rate should I enter?
Enter the rate that applies to your ticketed booking class and operating carrier. Rates can vary by fare, airline partner, and eligibility rules. Confirm the current rate before travel.
Can I use another Chicago airport?
Yes. Edit the airport name, latitude, and longitude. The calculator accepts any valid coordinates, so you can compare O'Hare, Midway, or another departure airport.
What is the ticketed mileage override for?
Use it when you know the official base sector mileage. The calculator uses that value instead of its geographic estimate, which can better match an eligible itinerary.
Are Premium Points the same as ANA miles?
No. They serve different purposes. This page estimates both with your inputs. Your final credited amounts depend on the applicable ANA rules and eligible flight details.
Does the calculator include layovers?
Yes. Add the number of connections per direction and your expected layover duration. The travel-time output combines those layovers with estimated airborne time.
Is the carbon figure official?
No. It is a customizable planning estimate. Enter a factor from your preferred carbon methodology when you need a different assumption or reporting standard.
Can I download the calculation?
Yes. After calculating, use Download CSV for spreadsheet data. Use Download PDF for a printable result summary with the displayed route assumptions.
Why should I verify results with ANA?
Program rules, booking classes, partner policies, and fare conditions can change. A final airline calculation may use ticketed point mileage rather than a geographic estimate.
