If you are given Prone condition and are flying, you fall. You aren't falling "instead," you are knocked prone and falling now.
Arrest a Fall says you take no damage on a success. It doesn't say anything about changing whether you would become prone or not. Falling Damage does it for sure, but a creature falling from a Trip is falling and receiving the prone condition from the Trip.
I'd argue that a flier knocked prone using Trip falls prone no matter what, but might mitigate their damage from the fall itself.
I definitely don't agree with your take. The rules for prone tell you that if you were knocked prone while flying you need to look at the rules for falling. Falling says you only land prone if you take damage from the fall.
If a flier successfully arrest their fall (easy check, but maybe you get lucky and they've already used their reaction) then they wont take any damage and will land on their feat.
Again, my assertion is that receiving the Prone condition while flying adds that "you fall" but doesn't replace "being knocked prone" with "falling instead of being knocked Prone." You are knocked Prone, and additionally you are Falling.
Hence why arresting the fall doesn't make you no longer knocked prone, it just prevents fall damage.
If you would be knocked prone while you're Climbing or Flying, you fall (see Falling for the rules on falling).
Success You fall gently, taking no damage from the fall.
Can you arrest a fall to avoid damage? Yes.
If you were falling and you avoided the damage, do you avoid the Prone condition from falling? Yes.
If you received the Prone condition from an effect such as Trip, can you arrest a fall to avoid that Prone condition from that condition? No, not even if you were falling.
The Prone condition from the Trip should stand, since Arrest a Fall doesn't address Prone conditions; it only addresses falling damage (which can cause Prone itself).
