You definitely want something durable, waterproof, big, well-ventilated, and with a footprint.I would suggest a 3-person tent to maximize living space and to enable you to put all your luggage inside. That being said, a giant vestibule isn't necessary, but having one for shoes or something small is important. Weight isn't important since you're flying, unless you will go over weight limit for your airline.I'd just look around a little, get an idea of your options, and then ask some more questions if you're still not sure. But definitely look for 3-season, 3-person stuff. You could get by with a 2-person, but the bigger it is, the more comfortable.

That is a big pack, if you throw the tent into a compression sack you should have no troubles getting it inside your pack. However, your question is kind of a hard question to answer considering we don't know what else is going to be in your pack aside from a sleeping bag and stove.

The Elkhorn 3 is very backpackable. In fact when split up between 3 people, it's very light.

Think Kevin Spacey in The Usual Suspects. Big Agnes is relatively unknown, as they're still a small company out of Steamboat, but their products are fantastic. Don't be put off by the wrinkled fly in the photo, I have a tent from them and it's the best I've ever used. The tents are bombproof (not literally). Highly recommend their products to anyone.

Hard to quantify reasonable conditions , but with proper care you should have this for at least three seasons if not more.It will last a long time as long as you take reasonable care of it. I have a twenty year old North Face Westwind that I use in the winter months. It looks brand new & essentially it is because of how it has been cared for.

Definitely, it has a great vestibule for storage, a nice blend of mesh and fabric for fall temperatures, and a nice lightweight design. Make sure to pick up a footprint as well to protect the floor of your tent.
