SriLankan Airlines has introduced daily flights between Muscat in Oman and Colombo from December 21.
Before that the airline operated five days a week flights between the two destinations.
SriLankan has made the decision to increase flights due to the increasing number of tourists visiting from Oman to Sri Lanka, the Airline said.
With the increased frequency of flights the Airlines officials expect to entice more tourists from Oman to holiday in Sri Lanka.
Sri Lanka has become a one of the most sought after tourist destinations among Omani nationals.
According to tourism statistics, the number of Omanis arrived in Sri Lanka rose 76 percent from 2,300 in 2012 to 3,850 this year.
With a global route network of 74 destinations in 37 countries, SriLankan operates a fleet of 21 aircraft - including wide-bodied A340 and A330 aircraft, and mid-range A320s. SriLankan also operates to Kuwait, Dammam, Riyadh, Dubai, Abu Dhabi, Bahrain, Doha, Jeddah, Amman, and Sharjah in the Middle Eastern region.
