What a waste!
My aunt flies from and to Singapore regularly, most times with just a carry on and for her last two flights she carried about 5 of my soaps with her with no problems. Definitely smells.... Them saying it's not allowed. Pfft..
I've ALWAYS taken my soaps and candles with me in my carry-on, for years, have never had a problem. Took them with me to Switzerland, England, Guernsey, Luxembourg, and all over the US, never ever ever a problem.
The flight out of DIA was even domestic, flying into San Francisco CA, so not even an international flight at that point...
I think they were just on a power trip. Honestly they basically do what they want when they want simply because they can.
They are probably using them right now.
Of course ever since 9-11 I get pulled out of line from TSA to get checked. EVERY. SINGLE. TIME.
My friend didn't believe me and when she and I flew out to Vegas a few years ago, they pulled me out of line and swabbed my hands. She couldn't believe it, and was surprised I was so calm. I told her, well, I'm used to it, they do it every time, so at this point it's just expected. (Seriously, not joking, it happens every single time) but the taking of my soaps and candles - this was a first. I've gotten questioned about them before, but never have had them confiscated until this time.
Oh well...
