Sri Lanka is one of South Asia’s most diverse and beautiful destinations, and its main international airport — Bandaranaike International Airport (Colombo CMB) — connects London travelers to every region of the country.
Flights from London to Sri Lanka are primarily operated as 1-stop routes via Doha, Dubai, Abu Dhabi, Istanbul, Muscat, and Bahrain. These connections are smooth, frequent, and competitively priced.

Most flights to Sri Lanka depart from the two largest UK international hubs:
Heathrow typically has more flight options and shorter total travel times, while Gatwick often provides competitive pricing, especially for passengers flying with Middle Eastern carriers.
