I have 30+ payments waiting for confirmation for nearly 48 hours.
Fees have been 0.00020+ per transaction.
Today, I sent BTC from Bittrex exchange to BlockChain wallet. Bittrex fee was 0.00020/BTC.
The Bittrex transaction was confirmed within an hour.
I do not understand how Bittrex transaction was confirmed in a short period of time and my other transactions with higher fees have not been confirmed.
The reason for it maybe the traffic and the volume of transactions that was happening around the system the moment you made your payments. The other possibility was the site that you used to send your bitcoins. So its either because of traffic, because of the site. But dont worry it will be fine your transactions will be completed though you need to wait a little longer.
