SriLankan Airlines (marketed as SriLankan) is the flag carrier of Sri Lanka. It was launched in 1979 as Air Lanka, following the termination of operations of the original Sri Lankan flag carrier Air Ceylon. Following its partial acquisition in 1998 by Emirates, it was re-branded and introduced the current livery. After ending the Emirates partnership, it has continued using its re-branded name and logo. The airline operates to 94 destinations from its main hub located at Bandaranaike International Airport in Colombo. SriLankan Airlines joined the Oneworld airline alliance on 1 May 2014.

Air Lanka was established as the flag carrier of Sri Lanka once the Sri Lankan government shut down the bankrupt Air Ceylon. Air Lanka's initial fleet consisted of two Boeing 707, leased from Singapore Airlines. One Boeing 737 was leased from Maersk Air and maintained by Air Tara. On 24 April 1980, the lease ended; Air Lanka received a replacement Boeing 737 leased from Royal Brunei. On 1 November 1980, Air Lanka commenced wide-body operations with a leased Lockheed L1011-1 Tristar from Air Canada. On 15 April 1982, Air Lanka received its own L1011 purchased from All Nippon Airways. With introduction of Tristar aircraft, the Boeing 707s were phased out and sold. Then another L1011 was leased from Air Canada whilst the third L1011 was purchased from All Nippon. On 1 May 1982, HAECO took over the maintenance of the two Air Lanka-owned Tristars, while Air Canada maintained two leased Tristars.

On 28 March 1980, Air Lanka signed a purchase agreement for two brand new Lockheed L1011-500 Tristars, the most advanced wide-body aircraft in the world at that time. The first Lockheed L1011-500 (4R-ULA) was accepted on 26 August 1982, at Palmdale, California. It was flown to Amsterdam as UL flight 566P. On 28 August 4R-ULA "City Of Colombo" left for its inaugural flight from Amsterdam to Colombo as UL566. It reached Colombo on 29 August. This was followed by second Lockheed L1011-500, 4R-ULB, "City Of Jayawardanapura". On 8 June 1984 the airline received its first Boeing 747-200B "King Vijaya" and the second joined later. The aircraft were used on flights to Europe and a few flights to southeast Asia.
