Matt, your wife is a peach to allow two weeks to hunt. You will lose 3-4 days traveling.
My buddy and I have made several trips by flying, renting a SUV, and setting up a forest camp. We each carried a 15"x15"x32" duffle bag for personal gear, a bow case for my buddy's compound, and a 60qt rolling cooler to carry our tents (5man base & 3 man spike tent), tarp, one burner gas stove, gas lantern, pots & pans, plates, bowls, utensils, cordage, game bags, etc. Make sure to keep weight under 50#. We flew SWA and where able to each have 2 -50# checked baggage and our carry on backpacks for free. When you harvest an elk, have it butchered & frozen and packed in waxed cardboard boxes for the trip home on the plane. Keep boxes under 50#. Ship your gear home 5-day ground UPS for cheaper shipping.
Keep up with the work outs, you will need it. Sleep you first/last night at lower elevation and get a scrip for Diamox from your Doc to help with altitude sickness.
Good luck and shoot straight.
