Yes another question about BitCoins

Okay say I withdraw from a book via BitCoins and wanted to use Bitcoins to pay for goods (Amazon). Do I just have the sportsbook send straight to my AirBitz account and then I spend the Bitcoins on there or do I need to go through Blockchain. I don't plan on linking my AirBitz to bank account at all. Thanks

I do not know anything about AirBitz. For me I get payouts sent to blockchain then I send to circle to get to my checking account
