In addition, third-party airline ancillary revenues — a potentially profitable resource for carriers — from hotels, rental cars, tours, credit cards and other non-airline business ventures will continue to grow in popularity as travelers take advantage of one-stop shopping and booking capabilities through these channels. Forrester Consulting predicts third-party ancillary revenues will rise 30 percent over the next five years. And a passenger survey by GuestLogix found more than half would take advantage of destination-related offers onboard a flight, particularly services that could be utilized immediately such as entertainment and attraction tickets, ground transportation and tours.
