Just completed the tripy from LFBD airport near Asobo Studio to KSEA airport near Microsoft HQ with the Boeing & didnt get the steam achievement either.
I’m not sure why this is,but it seems like after loading a save ,the stuff you did before that safe didn’t happen & it instructs you to fly all the way back from where you started.Tried to complete it again in another attempt to unlock the achievement.Alas
