Information :-

1. You can always send at a fee recommended by this site : https://bitcoinfees.earn.com and https://jochen-hoenicke.de/queue/#24h gves a live view of mempool .
2. A strong alternative to blockchain wallet is ELECTRUM . I have not used blockchain for months as it has no RBF option till date .
3. You can always come to me , as it is free .
4. In Electrum, generally the transaction is automatically marked as RBF (Replaceable By Fee) . This is an excellent option to increase fee anytime for stuck transaction and get it confirmed if you want to spend money .
5. If you want to save money . Send the transaction at 200 sats/B when mempool is low . You can google "mempool" and click first link to know more . If it is high you can put into an accelerator .



Also I collected some info from this forum :

I had no luck getting my transaction confirmed. But abandoning the transaction in bitcoin-qt worked:

Go to the Bitcoin Core datadirectory and delete the mempool.dat file
Restart Bitcoin Core with the -walletbroadcast=0 option
Go to the transactions list, right click the transaction that is stuck. It is no longer greyed out! Choose the Abandon Transaction option.

            Backup wallet file. Always have your seed words written down but it's quicker to restore a backup wallet file.
            Close Electrum. Find and open the wallet file.
            Look for the last tx in the verified_tx3 section. Note it's first few digits so you can recognize it.
            Now look in the transactions, txi and txo sections and remove the records that follow this noted one being careful to get the 
            trailing comma on the previous one so the JSON syntax isn't broken. That should clean up the unconfirmed tx.
            Save the file and disconnect network so it cannot sync to update again.
            Open Electrum and check the unconfirmed tx is not shown.
            Create the tx you want again with higher fee and save to disk.
            Optional: Sign offline (or online) and save to disk.
            Reconnect network and load the tx from file. It will let you send but probably gets a spent outputs error.
            To send using a pushtx page: You can open the saved tx file and select the hex raw tx digits (without quotes) for pasting into a 
            push site. All the sites I've tried have also given spent outputs error. The old tx needs to be dropped from the mempool on the
            pushtx site and at least some miners for it to get confirmed.


If the transaction was made from Bitcoin Core, you can use "replace by fee" to send a proper fee to unstuck it. I've never needed to do that. There's also the option of running -zapwallettxes (put -zapwallettxes in front of the bitcoin executable path in a direct access if you are using windows, which I hope you arent) then this would drop the tx and give your money back. Additionally you can reach for some miner to mine it for you. If you are not using Bitcoin Core then I cannot help you with that, you will need to contact support of whatever wallet you are using. -zapwallettxes only removes/drops unconfirmed tx in his mempool 
and once it's broadcasted to other nodes, he can only wait for it to get confirmed or dropped
