Who bitcoin get the transaction fee? part2
Miners receive the fees. Really.

If you're not getting fees, either you mine in a mining pool that doesn't keep track of fees and block reward separately, or you mine for a mining pool that doesn't distribute transaction fees to its miners, or you aren't including transactions in your blocks.

So either 1) you get the transaction fee, but you don't know it, or 2) the pool keeps the transaction fee, or 3) the pool includes no transactions and therefore gets no fees.
