I wonder if anyone has the experience of bringing antique clocks on board a plane. Would it be better to check in the clocks as luggage or to hold them as a hand luggage? Either way, will the customs officers open up the bubble wrappings to check the clocks (they probably wouldn't care to pack the clocks back nicely), or cause any inconvenience when checking in, especially that the movements are made of metal? Please pardon me for asking such ignorant questions, and please let me know if my questions shouldn't belong to this forum (I will delete the thread). I am going back to my home country soon, and I thought I could save some shipment fees this way. Thank you for any feedback.
