One-stop security (OSS) can be defined as 'the process of screening people for prohibited items once, at the beginning of their journey only,' thus enabling passengers who arrive on an international flight and have a connecting flight to bypass security rescreening. In 2025, the UK and US governments reached a historic agreement that enables passengers traveling on certain routes between the two states to benefit from the initiative. This discussion will illustrate the value being delivered through by OSS and provide insight into ambitions for growth of the program while maintaining the highest levels of security.
