London City Airport (LCY) is a specialized hub primarily for business travelers in 2026, restricted to aircraft that can handle its steep 5.5° approach. The main carrier is British Airways (via BA CityFlyer), serving major European cities and domestic routes. Other key airlines include KLM (connecting to Amsterdam), Lufthansa (Frankfurt and Munich), Swiss (Zurich and Geneva), ITA Airways (Milan and Rome), and Luxair (Luxembourg). A supportive peer "transit" note: Aer Lingus also operates frequent flights to Dublin and Belfast. Because the runway is short, you won't see large Boeing or standard Airbus A320s here; instead, you'll fly on the Embraer E190 or the Airbus A220, which offer a much faster "curb-to-gate" experience than Heathrow.
