Checked baggage is regularly checked at the airport by the qualified security authority that may even request a more thorough screening of the current security protocols.

It often happens that travelers are locking their checked baggage, yet that does not present an issue for the transport security authorities, as they are provided with a specific device that opens locked baggage with no harm to it.

It is not uncommon for some passengers to lock their checked baggage; however, the devices best suited for this purpose are specially designed locks (such as Travel Sentry) that can be unlocked by transport security authorities without risking damage or delaying baggage.
