- What is this?
- A simple way to get accurate great‑circle distances between up to three airports using IATA codes. These numbers feed directly into sustainability and ozone‑related emissions reporting.
- How does it work?
- We use each airport’s latitude/longitude to calculate great‑circle distances. Choose kilometers or miles, see pairwise legs (A→B, A→C, B→C), and optional route totals when three airports are selected.
- How do I use this for my expense report?
- The distances produced here can be exported to CSV and attached to expense reports as supporting documentation. This keeps reimbursements, audit trails, and sustainability reporting consistent, especially for EU/UK programs that require travel activity and mileage transparency.
Disclaimer: The Airport Distance Calculator provides great-circle estimates based on published airport latitude and longitude coordinates. Distances are calculated using the haversine formula (WGS-84) and may not reflect actual flight paths, routings, or airline mileage programs. Results are intended for informational and compliance-support purposes only, such as sustainability and emissions reporting, and should not be used as the sole basis for travel planning, reimbursement, or regulatory filings. Organizations remain responsible for verifying calculations against their own reporting standards and applicable regulations.
