bc.info support answer is
"Hello,
An unconfirmed transaction will eventually be accepted into a block by whichever mining pool mines the block, or the transaction will eventually be rejected by the bitcoin network. If it eventually is rejected, then the funds would remain at the bitcoin address they were sent from. The only thing you can do at this point is to wait and see if the transaction is accepted into a block. Like all wallet providers, Blockchain.info has absolutely no control over this, and cannot expedite transactions. This is always dependent upon the bitcoin network of miners, which we are not a part of.
Blockchain.info wallets utilize dynamic fees. The following link explains how this works -
