This transaction didn't need to be accelerated. At 1,287.141 satoshi/byte, it paid about 5 times the minimum fee for an instant confirmation. It just happened to take 24 minutes before the next block was found after this transaction was broadcasted.

Was this a withdrawal from Bittrex? I've noticed before that they pay thousands of dollars more fee than needed for each of their transactions. I don't really understand their business decision when it comes to paying fees, they probably do this at least 100 times per day, that's half a million dollars extra for miners!
