This page explains what TSA Pre✓ and Global Entry are, who is eligible to use them, and how they can apply.
The US Transportation Security Administration (TSA) has developed a pre-screening process called TSA Pre✓. This allows qualifying travellers, including Virgin Atlantic passengers, to enjoy faster security screening and use dedicated TSA Pre✓ lanes at participating US airports.
With TSA Pre✓, you don't need to remove shoes, light jackets or belts when you go through security. Compliant liquids and laptops can stay in your hand luggage as well.
UK nationals can use TSA Pre✓ by joining the Global Entry programme, which also allows a faster entry through US immigration on arrival.
