In my family, the tree is the big deal. Or should I say trees, since growing up we always had multiple. The big one is "Dad's" with only Hallmark ornaments - 600+ at recent count; the others a variety of other sizes and decorations for a total of 3-7 trees around the house.
My own tree has followed me through the years, from home to Lubbock to Dallas. It's decorated with a hodgepodge of ornaments collected through the years, with heavy emphasis on snowflakes!
This year I've added a SWA themed tree for my work cube. Along with a few glass planes and SWA heart, I have the SWA collectible ornament for each of the Christmas I've worked here (2 and counting!) I've snagged a picture with my phone - not too clear, but captures the spirit!

Yes, the tree skirt is the sky and that's a Southwest plane stitched in the front.
