Overview

• Eleven UK airports—including Gatwick, Birmingham and Edinburgh—have deployed computed tomography scanners that produce detailed 3D images of carry-on bags.
• At those locations, travellers may keep liquids and electronics in their luggage and carry containers holding up to two litres.
• The rollout was delayed past its original summer 2024 target by technical problems and supply-chain setbacks, forcing some airports to briefly reinstate the 100 ml rule.
• Liquids in vacuum flasks must still be poured out because the new scanners cannot penetrate double-layer insulation.
• Aviation Minister Anthony Browne urges passengers to verify liquid restrictions before travelling, as most UK airports have not yet upgraded their checkpoints.
