SimBrief calculated a flight level of 80 for this flight, which is definitely too low. Do you know what could be causing this?
The airway segment SAPRE T544 WIL is restricted to below FL095.
The correct route for jets from Geneva to Zürich is SOSAL N871 BERSU (below FL185 except early morning and late evening).

Tim
Edit: I have bumped the more “typical” route back to the top of the list.
