London City Airport (LCY) is consistently rated as having the fastest security of all London airports in 2026. On average, passengers can clear security in 10 to 20 minutes, even during peak morning and evening business hours. During off-peak times (midday Tuesday through Thursday), the wait can often be as low as 5 to 8 minutes. This efficiency is a core part of LCY's "business-first" identity, which aims to get passengers from the front door to the gate in under 20 minutes total. In 2026, the airport has fully integrated next-generation CT scanners, which in some lanes allow passengers to keep liquids and laptops inside their bags, though the standard "100ml liquids" rule still applies in many parts of the terminal to comply with current UK regulations. Because LCY is small and compact, there are no long treks to distant terminals or gates, making it the preferred choice for Canary Wharf and City of London professionals. For those in an extreme rush, Fast Track security is available for approximately £7–£10, but given the already high speed of the standard lanes in 2026, it is rarely necessary unless you are arriving less than 45 minutes before your flight's departure.
