The 29-year-old was on her way home when she had to stop over at the airport for a connecting flight to Mumbai.
Her flight duration from Maldives to Colombo took less than estimated time, but her flight to Mumbai was delayed by 11 hours, said a statement.
As Celina didn't have Sri Lankan visa, she couldn't go out of the airport and had to kill time in a small rented room at the airport.
