Here are a few things to keep in mind:
* Security: You won't be asked to remove jewelry at airport security unless it sets off the metal detector. If it does, you might be asked to remove it for further inspection.
* Loss/Theft: It's generally recommended to keep valuable jewelry in your carry-on, as checked luggage is more susceptible to loss or theft.
* Comfort: Consider the comfort of wearing jewelry during your flight, especially for long flights. You might want to remove rings or earrings if your fingers or ears tend to swell.
* Travel Insurance: If you are traveling with very expensive jewelry, consider getting travel insurance that covers loss or theft.
* Customs/Declaration: Depending on the country you are traveling to, you may need to declare valuable jewelry upon arrival, especially if you plan to sell it.
In summary, bring your earrings! Just be mindful of security, potential loss, and your own comfort.
