SriLankan Airlines says it will extend the suspension period for passenger flights until the 30th of this month.
This is because the rest of the world has not yet cleared its travel limits.
SriLankan Airlines said in a statement that cargo flights will continue.
In addition, special flights will be operated on demand.
SriLankan Airlines has also introduced a special telephone number to address existing issues.
The problem can be reported by dialing 011 7 771 979.
