When airlines adopted ticketing technology in the late 20th century they were on the cutting-edge; unfortunately as technology has moved on airline now find the backend systems they rely on to be long antiquated. From travel agents to passengers, everyone in the industry has been frustrated by the backends that don't live up to the expectations of modern consumers.
