Slappy1, I've go to go along with your friend and "Flying Elf", although non-revs have been known to snag an upgrade now and again nowadays chances of an upgrade are plenty slim, (upgrades to the frequent flyers) all you can do is think a good thought, carry your lucky charm (maybe two) and smile, smile, smile.
Insider tip for the first time (long haul flight) non-rev---Once you're through security (assuming you can't cram all the necessities in your purse ) rearrange your carry-on using layers. One of the facts of non-rev life is no room in the overhead, so expect your carry-on to end up at least 15 rows away. When you finally get a chance to get to your carry-on, it'll be a lot easier if eveything you'll need is right on top within easy reach.
My long haul kit--sweats, noise canceling headphones, bottled water, lip balm, eye shades, iPod, book, back pillow and sandals (trust me, you do not want to go into the lavs wearing only socks ). I'd also suggest besides getting up and walking, doing some in-seat exercises, sometimes I get my seat mates involved--"everybody flex"

One last thing, as an official travel companion you must abide by certain rules.. ( uh-huh) one being you must bring back a great souvenir for your official travel sponsor.

Have fun and let us know how it goes.
