Airlines Reporting Corp. has invested an undisclosed amount in Blockskye, a blockchain-based inventory booking and transaction management supplier. ARC and United Airlines earlier this year announced they were testing a blockchain-based ticket reporting and settlement system with one of United's largest corporate accounts. That has shown that "there are near-term use cases for blockchain that drive strategic benefits and pull these already close relationships even closer," according to ARC president and CEO Mike Premo. The investment is ARC's first foray into venture capital financing.
