I've been asked about why my boarding pass didn't have the same name as my passport once, back when I didn't put a middle name. I'm from France where we traditionally have 3 first names: <actual first name> <godmother|father's first name> <grandmother|father's first name> (at least that's how I was named). For paperwork purposes in the US I had to make up a middle name so I use my second and third names. Say Albert Bernard Charles Dupont would be: "Albert" "Bernard Charles" "Dupont". This way it's also consistent with my passport.

I also don't put my name's accent in most computer systems in the US (é). I have it on Linkedin though, and it trips a surprising amount of automated recruiting emails.
