This will make it easy for Bitcoin holders to make transactions to pay for airport tickets, and I think airport managers are keen on technological advances, because they have many passengers and some of them will use bitcoin to pay for airlines. so Bitcoin holders don't need to exchange their Bitcoin with fiat money in that country.
The more airlines that accept ticket payments using bitcoin, the more passengers there. Airports will be increasingly crowded with aircraft passengers, meaning that the economy is spinning faster, welfare impacts are increasing. The government must be aware that technological progress will have an impact on state revenues, while bitcoin is proof that payment technology can be done without third parties, and cheap.
