Ease up pardner
Glacier :
Man you got to slow down! Bring your flight bag, toss the coat (unless you want to wash your golf cart in it) pack your parka (in case there is another winter like this last one!!) and you will need some -40 sorrells in case you divert to Churchill on your way to JFK.
Do not worry about a life partner as one will be supplied, you will have to buy your own pump and carrying case for him/her. Not too worry as these plastic beauties fit under the crew rest bunk nicely along side your carry on of standard proportions. Also they are much cheaper in the event you decide to upgrade later on.
Good Luck.
