Can you push flying creatures into a wall?

[dexmark]

Just curious about flying rules:

 if a flying creature always can see above a wall (so technically they are above the wall), can you push (Force push) them to a wall or push them through a wall with a passive attack trait? My opponent may argue that they are way above the wall..

Just preparing for a battle with flying creatures. I am playing Forcemaster where I have tons of push spells. I just want to be ready with this rule.

You can bash a flying creature into a arena wall. A wall on the border of a zone would not effect flying creatures.

Thanks.  With this knowledge the Angel with the range sweeping push looks mighty fine right now..

So could a flying creature pass over a Wall of Fire without receiving damage?

Yes
