We have now made some changes to our route calculator, which will improve mainly shorter routings like this one, which to a higher degrees will use airways when they exist also for short hops. If you try now, you’ll see this end result:
With the final route being EDDF OBOKA Z28 DIBIR T601 OKIDU DCT INKET EHRD.
Please have a look and let us know what you think.
Kind regards,
