London City Airport (LCY) is famous for having some of the shortest wait times of any major international hub, making it a favorite for business travelers. As of early 2026, the average time to clear security is typically between 10 and 20 minutes. Because the airport is significantly smaller than Heathrow or Gatwick and features a single-terminal design, the "curb-to-gate" experience is remarkably efficient. However, travelers should still be aware of peak periods; Monday mornings (5:00 AM – 9:00 AM) and Friday evenings often see a surge in corporate commuters, which can push security wait times closer to 30 minutes. LCY has also implemented advanced CT scanners in several lanes, allowing many passengers to keep liquids and electronics inside their bags, further speeding up the process. Despite its efficiency, the airport recommends arriving 90 minutes before domestic flights and 2 hours for international departures to account for any unexpected operational spikes.
