London City Airport (LCY) does get busy, but its "business" is very different from that of Heathrow or Gatwick. Because it primarily serves business travelers heading to the City of London and Canary Wharf, the airport experiences extreme peaks during weekday mornings (6:30 AM – 9:00 AM) and evenings (4:30 PM – 7:00 PM). During these times, the terminal can feel quite crowded as commuters rush for short-haul European flights. However, because the airport is designed for speed—with a promise of 20-minute check-in and 15-minute arrivals—the "mess" is usually well-managed. In 2025/2026 data, the airport handles about 3.7 million passengers annually, which is a fraction of Heathrow's 84 million. If you travel on a weekend or in the middle of a Tuesday afternoon, the airport is remarkably quiet and can feel like a private terminal. The airport's strict "curfew" (it closes from Saturday afternoon to Sunday morning) also means it avoids the 24/7 chaotic grind found at larger international hubs.
