I have some, though not as many as I'd like, as I'm quite choosy about getting hold of good condition originals with all the relevant gatefolds/inners/booklets etc., so the vinyl collection is very much an ongoing project.
I have LJS with the stash box sleeve, a really nice Japanese promo copy of Flight Log with booklet, lyric sheet etc., and quite a few of the early Grunt releases, but they're all played and enjoyed regularly, not just stored in plastic sleeves in a temperature-controlled vault.
Probably my favourite Airplane-associated vinyl artifact is Paul's Blows Against The Empire, with the gatefold sleeve and that nice textured booklet with lyrics and illustrations, which looks almost ridiculous when shrunk to CD size. CDs are okay for convenience and durability, but there are downsides: they skip worse than records, and some won't play at all; there's the aforementioned sleeve/booklet shrinkage problem, which ruins a lot of truly great cover art - oh, and the plastic CD jewel case is surely the most badly designed artifact of the twentieth century.
Generally, I just love old vinyl; the look, feel and smell of it, and the sense that there's history aplenty in them thar grooves.
Incidentally, the first Airplane vinyl I ever bought was a cheapo RCA reissue of Crown Of Creation back in the early 80's. The vinyl was so thin it began to warp horribly within hours of me removing it from the sleeve (or so it seemed), and it soon became quite literally unplayable, despite my attempts to flatten it beeneath several heavy objects. To this day, it remains the only record that I've ever thrown away...
