Trying to do a mileage run on China Eastern but avoid the fare codes that DON'T get any mileage credit on Delta (particularly avoid the Q fare that keeps coming up on the PVG-JFK return leg).
How do I do that? Looks like I'm really just trying to avoid Q fare on MU.
You can try something like this, / airline MU; f ~bc=q.
"~" or tilde acts as a negation, or you can just specify which booking classes you want, e.g., /f bc=y|bc=b|bc=q
