Maybe he's just testing them all out, like Goldilocks ;)

AWESOME! HILARIOUS!!

Funny, but he doesn't really look the part - dark hair, middle-age, average height, dark suit, light blue shirt, tieless, black rollerboard carryon, leather computer bag, laptop, cellphone with extra large/long antenna...

A truly evil person with lots of time on their hands might be tempted to report him to pilot/FA/TSA as acting strange...

Not the same at all, since this guy flys all the time (and in F), but I've noticed that, for whatever reason, people boarding the AA SAAB flights from SAN-LAX never seem to understand the concept of assigned seats. They grab any seat they like, even discussing with each other where they'd like to sit. (They also make endless remarks about how small the plane is, even on the nice roomy 240+Bs with the extra few inches of bin space!)

What? Nobody yelled "Hey this isn't coach! You don't belong here!"

It is clear to me that the gentleman is a classic Type A personality who is simply marking each seat with his scent.

Yesterday, "Goldilocks" bounced around the cabin, trying out as many as three seats in First this time before ending up in his assigned seat in the bulkhead row. With two seats and an aisle separating us, I was still not close enough to ask him why he does this, but yet far away enough to feel safe by the window. Used to the routine, a FA knowingly just rolled her eyes.

I mus say, I find this truly bizzare...but intriguing at the same time!

Haha, I like that. :D

OCD perhaps?
