The national airline of Sri Lanka, SriLankan Airlines, has a major presence in Colombo thanks to its city office, which acts as an essential center for business and passenger services. This office is perfectly situated in the center of the city, offering easy access for both business partners and tourists. It is located at Level 3, East Tower, World Trade Centre, Echelon Square, Colombo 1. In order to guarantee that help is available during periods of high travel demand, the office is open Monday through Saturday from 8:30 AM to 5:00 PM, including public and commercial holidays.

SriLankan Airlines opened a renovated corporate office at Sir Baron Jayatilaka Mawatha, Colombo 1, in April 2021. The airline's corporate offices, passenger and cargo sales, and SriLankan vacations are all housed in this building, which combines Dutch colonial architecture with contemporary interior design. A comprehensive reorganization to reduce operating expenses included the move from the World Trade Centre, which saved LKR 90 million a year. Interestingly, the only real estate asset owned by SriLankan Airlines is this property, which was first owned by Air Ceylon and then by Air Lanka.

The Colombo city office still plays a vital role in customer engagement even though the corporate headquarters have relocated to the Airline Centre at Bandaranaike International Airport in Katunayake. Bookings, cancellations, rescheduling, online check-in help, baggage management, and details on in-flight services are just a few of the services it provides. The office also offers assistance for specific services including healthcare, pet travel, and unaccompanied kids. Visit- Sri Lankan Airlines Colombo Office in Sri Lanka
