Most of the people wouldn’t give a second thought for flying on SriLankan Airlines (UL) based in Colombo, Sri Lanka. I had visited Colombo few times, and flown in/out on Singapore Airlines. The airline has pretty good coverage within the Gulf region, India, and four Chinese cities via Bangkok. The fares, both in economy and business, are competitive.
The only drawback is the fact that UL doesn’t belong to any alliance. They used to be very close partner of Emirates, but the partnership soured rather suddenly two years ago. You can credit the UL flights, in addition to their own program, to Etihad or Malaysian. Overall UL’s FlySmiles doesn’t look worth accruing unless you are flying heavily on their metal.
