Check the weather report a day or two before you fly. Pick the skis you want for the expected weather. I've got many more Rocky Mountain ski days on firm snow than on fluffy snow. Take the skis you'll use most and rent for the day or two you may get different snow.
Check the airline sports baggage rules for each year for each airline you'll fly. They change. If a ski bag & boot bag count as one item, they share the one item weight limit. I put my around-town snow boots into the boot bag, along with my helmet, and hand-carry my ski boots onto the plane.
If a leg of your trip is on a smaller plane, even a small jet, don't be surprised if some the ski baggage isn't loaded due to weight or space limitations on the plane. It'll come in on a later flight, maybe the next day. Plan for what you can rent and what you absolutely need to ski that first day.
