This seems like one of the more ill-advised passenger moves I’ve seen lately. A New York and Philadelphia-based influencer claimed she checked $12,000 worth of stuff on a flight back from Cancun, including a valuable bag and ring. And she says that the airline’s staff stole it by breaking into her bag.
Even if she’s on the level, she has no idea who took her stuff. She… put $12,000 worth of stuff in her checked bag in Mexico? In Cancun..?
Don’t check things that are super-valuable, forget theft an airline can lose your luggage. You can insure your valuables separately. Remember that for international flights checked bag liability is limited under the Montreal Convention. And good luck proving you had checked those items in the first place without having separately declared them (if you’re a TikToker at least videotape the items in your bag as you check them in, the lack of video documentation here makes me somewhat more skeptical of the story).
Of course putting items in your carry on bag, above you in the overhead, can also entail risk especially on long haul flights when everyone in the cabin goes to sleep but there’s still less risk. You can keep truly valuable items with you, under your seat, or at least concealed.
