Corporate Traveller is not accepting bitcoin. It is using Bitpay's services to accept fiat.
Corporate Traveller, a subsidiary of the Flight Centre Group, has just announced that it will be accepting Bitcoin (BTC) and Bitcoin Cash (BCH) due to increased demand from its clients.
Corporate Traveller is the UK’s largest business travel service and will be processing the cryptocurrency payments through BitPay. The payments will be converted to Pound sterling (GBP) and settled within two business days.
The company has said it sees the potential in blockchain technology and wants to be the first in their sector to integrate cryptocurrencies as payment.
