Travel management companies booking through aggregator Ypsilon now can book on behalf of clients using virtual cards, thanks to an integration with the Amadeus B2B Wallet virtual card platform. The integration will offer Germany-based Ypsilon's agency customers the flexibility to pay with virtual credit cards—and then pass the billings along to the clients—to optimize cash flow. They also can use virtual prepaid cards to take advantage of airline rebates for prepaid bookings. Aggregators like Ypsilon help get low-cost carrier content to corporate travelers, as LCCs typically don't participate in global distribution systems, and LCCs comprise about 25 percent of seats in Ypsilon's key European markets, according to the company. Since bringing its B2B Wallet to the U.S. in 2017, Amadeus has been building out the virtual card platform around the world. In February 2019, Amadeus added Barclaycard's Precisionpay virtual corporate cards to the platform. Sabre has bolstered its own virtual card wallet, as well, integrating virtual Visa commercial cards in April.
