Did you turn lucky or does this even happen in the real world? I first thought it could be something related to child-pays-for-parent, but that doesn't seem to be the case here. Both outputs are unspent.

I really don't understand what we all want, when the transaction fee was high we all complained to the high heavens that it's was exorbitant  and now the fee is low we are still complaining. I expect that what should be done is to give credit to those who went to activate segwit to have witnessed fees ridiculous as this.

The issue isn't about the amount, Regardless of whether it's 2 USD or 20K USD, as long as the size in bytes and the total fees are reasonable with the network TX level it will get confirmed.
For the current TX time, I would say something along the range of 30 Satoshi per byte minimum, if you want it confirmed within few hours, but with 4,6, it wouldn't be strange to have to wait for days until a miner include it.

Wow, someone seems to be lucky here. I’m  always afraid of sending money/bitcoin with a low priority fee. I use the high fees,  though it’s costly, but I do it to avoid loss. I’ve  experienced  some 30 days a transaction with low fee, and it never got confirmed after 24 hours, and I was surprised when it continued till the next day without getting confirmed. 

Hey OP did you use any accelerating services to push your tx to get confirmation ?

Yes it is indeed, and I think it would go through even if you sent it today... it would just take a LOT longer than it used to. But eventually it would. I sent an 11 sat/b a few weeks ago and it went through within 24 hours!
