A new codeshare agreement between Sri Lanka’s national carrier SriLankan Airlines and Australia’s flagship carrier Qantas Airways announced in September 2014 came into effect from 26 October paving the way for increased tourism potential between Sri Lanka and Australia.

Passengers travelling to/from Australia on Qantas will have the opportunity of connecting to/from SriLankan Airlines’ thrice daily service from Singapore to Colombo. SriLankan will offer its customers travelling to Australia via its common gateway in Singapore, the benefit of connecting to Qantas’ daily services between Singapore and Brisbane and Melbourne and its double daily services to Sydney.

Passengers can now enjoy the convenience of a single ticket, interlined luggage and earn frequent flyer miles all the way in both directions.
The new codeshare agreement is expected to be a boon for the large Sri Lankan expatriate community in Australia, who could avail themselves of the enhanced connectivity and convenience of travel when visiting friends and family in Sri Lanka.

SriLankan has recently increased flights to Singapore from twice daily to thrice daily and as a result passengers to/from Australia will now have very good connectivity when they choose to use these codeshare flights. SriLankan will now be operating 28 services a week to Australia by virtue of this codeshare operation.
