How to interpret the behavioral psychology of posting air tickets?

On the one hand, it feels a little secretly satisfying to fly and show off your air tickets. After all, flying is currently the most high-end way of travel in the world, and it shows that you live a high-end life. Usually couples show off their affection. On the other hand, you will find that this group of people will block part of their ticket information, and the destination will be leaked to show off their travel destinations. They hope to gain the envy and praise of others, and they have some vanity to show off.
