Why people like to show off on their social media when they are about to travel?

Some examples

Dsiplaying on social media a photo of themselves at the airport with a photo of their passports and quoting "Vacation".

Posting and posting photos of their trip every 5 minutes.

Do some people do it for the sake of letting people know they can afford to take a trip to other countries? Like to make other people envy or something?
