In left front pants pocket: Uniball pen, mechanical pencil, checkbook, business card case.

In right front pants pocket: keyring, Palm VII. (I usually wear pants with big cargo pockets...)

In right rear pants pocket: wallet.

On belt, right: Nokia 5160 phone, in belt-clip case. (I don't need a fancier phone, with the Palm VII to handle wireless-Internet needs.)

On belt, left: Leatherman Wave and Mini Mag-Lite, in combination belt holster. (Though I wouldn't wear that if I were going to be flying, of course.)

In shirt pocket: sunglasses (except at night...if I'm wearing a shirt without pockets, the glasses will often go in my inside jacket pocket)

And, of course, on my wrist, my ancient Casio Databank watch. Not that I need the Databank or calculator, with the power of a Palm VII at my disposal, but old habits die hard, and it has other useful things like a countdown timer, stopwatch, and multiple timezones. (I used to go through watchbands like nobody's business, until I replaced those cheap rubber/plastic watchbands with a Speidel expanding watchband. The paint's rubbing off it in places, but it's lasted far longer than any other watchband I've ever had and is still mechanically sound.)
