No two separate
When flying, skis & poles (normally packed together) and your boot bag, are normally considered one piece of luggage. You pay your airline's normal bag fare, if they even charge one. Each airline luggage charges differ.
Cross countries skis require a different type of boot. These boots only attach to the ski at the toe allowing your heel to move off the ski as you move. On downhill skis your entire boot is attached to the ski. You can read more about the differences here http://skiing.about.com/od/beginning skiers/a/ccdownhill.htm
Most likely because there is a bigger chance that you will fall out of your skis while skiing alpine. Also in Cross Country technique sometimes you need to lift up your heel.
Snow skis can be sold at local auctions or car-boot-sales. Online markets such as Amazon and ebay could also be used as they offer a more convenient sale as well as a wider customer base.
ski boots, because they are useless with the skis
Cross-country touring skis are longer, wider and more limber than skating skis, and the edges are different because tourers push off from the part of the ski under their boot and skaters dig in the edge. It would be very awkward to skate on a touring ski, and equally awkward to tour on a skating ski.
To remove cross-country ski bindings, first, ensure the skis are on a stable surface. Locate the release mechanism on the binding; this is often a lever or a button. Press or lift the mechanism while simultaneously pulling the boot away from the binding. Once the boot is free, the binding should remain attached to the ski, allowing you to repeat the process for the other ski if needed.
That is called a pre-cognitive dream - quite unexplained, and a piece of firm evidence that ordinary passing time is not the only form of time.
You can't get skis.
"Les skis."

Because if skis were short and round, they would be called "bicycles".
