"AnonymousCoward" is the default user ID on Slashdot: "News for Nerds, News that Matters". A great timewaster, but also a treasure trove of geekery and humour. Much like this place, perhaps!
I've been keeping an eye on Qantas eBay items. Bought some stuff, mostly airliner models - I have a "Wunala Dreaming" sitting on top of my monitor.
Business and First Class amenities kits go for between $5 and $20, depending on how complete they are and the phase of the moon. I occasionally see someone trying to flog off economy long-haul kits with not a great deal of success. A lot of memorabilia - menus, boarding passes, inflight magazines, first day covers.
Also useful to keep an eye on "Quantas" when searching to catch similar items from sellers without a clue.
Luggage tags come up occasionally. I got two with my QFF silver kit, but I wouldn't mind a third for my carry-on, just in case I slip up and leave it somewhere. As my wife did recently - left her carryon with laptop, camera etc at the checkin counter and it didn't get returned to her until just before boarding and after she'd rung me up and confessed.
