The presence of Tropical Storm Maria in the area has forced LIAT to cancel two Barbados flights today.
The carrier said LI 374 from Barbados to St Lucia and LI 375 from St Lucia to Barbados have been cancelled.
LIAT said it was forced to cancel the flights to ensure passenger and crew safety.
Passengers who have been booked on these flights will be allowed to rebook and have all change fees and fare differences waived only if they do so on or before Tuesday, September 19.
LIAT said passengers who decide to travel but are unable to complete their journey due to disruption caused by weather conditions will not be provided with meals, transportation and hotel accommodation. Passengers with onward connections are advised to contact the respective regional and international carriers.
