Most airlines, most of the time, only show up on the newspapers if the news is not that good. But on the IT side they are leaders of the pack using a sort of like blockchain solution for the sellings of the seats. There are multiple websites on which you can book a seat on almost all flights in the world. Now hey just want to speed things up and decrease the costs even more. If you just think of it, aviation is great industry in almost all aspect (except for their employees). Think about the radars, technical inspections of the airplanes, booking systems, safety measures, automatic pilots and so on. They already evolved 10 times faster than the car industry.
So a aviation blockchain ICO would for sure attract my interest!
