Japan Airlines and User Preferred Routes

Japan Airlines Corporation was established in 2002 and is the holding company of a group of air-transport companies.

Did you know? 

• A User Preferred Route (UPR) is a unique flight path for each aircraft instead of following the conventional approach of flying along predetermined aviation routes set by air traffic controllers (ATC).
• Depending upon the prevailing weather conditions at the time, UPR allows an airline to fly along what it judges to be the most efficient route for each type of aircraft used. The system helps to improve operational efficiency by providing each aircraft with an optimal flight path and shortening flight times.

What are we doing? 

• JAL has started trials of UPR for scheduled flights serving on 4 routes between Japan and Hawaii: Narita – Honolulu, Narita – Kona, Osaka – Honolulu, and Nagoya –Honolulu. 

What is the result? 

• If USP were used on all of its flights operating between Japan and Hawaii, JAL has estimated that it could reduce its fuel consumption by about 1.93 million litres, resulting in a 4,700 ton reduction in greenhouse gas emissions and a reduction in fuel costs of 180 million yen per year.
