Hey RS travellers - This question is about domestic travel but might apply to international as well.
My sister is travelling from Reno to Boston in a few months to attend a fancy wedding. She has to bring along a dress that she paid a lot of money for. She doesn't want to put it in a checked bag because every time she's flown to Boston her checked bag has been lost. She's also nervous about putting it in her carry-on bag, as sometimes those are checked at the last minute and thus could also get lost. She can try to squish the dress into her personal item bag (it's not a ball gown) but then she wouldn't have much room in the bag for anything else.
I'm wondering if anyone has ever heard of an airline allowing you to bring something like a dress (in a light-weight garment or dress bag) on board, in addition to one's carry-on bag and personal item? I seem to recall hearing about some exceptions (e.g. people being allowed to bring skis or musical instruments), but have never taken this data myself. Thoughts?
