I do it all the time - though my friends got sick of me checking into F lounge 3 times a week and started heckling me for it.

I don't see it as showing off. I just like to document my travels and be able to reflect back on my social timeline.

Rule of thumb. I have no colleagues at work present or past on my social media. I only have friends from university and close family and friends through other connections.

This thread will ultimately turn into a DYKWIA and/or "they are only flying economy" bashing...
