Caribbean carrier Liat was forced to cancel all flights today after pilots staged a sick-in and refused to fly.
Over the past year labour relations at the carrier have been strained, and pilots in November threatened to strike.
Earlier this week, pilots who are represented by the Leeward Islands Airline Pilots Association, said they had no choice but to "withdraw enthusiasm and issue strong resentment" after failing to resolve a dispute over a claim for retroactive pay.
"Clearly the first people to feel the impact of any industrial action by the pilots will be the small man - the taxi driver, the hotel worker, the airport vendor," said Liat Acting CEO Brian Challenger in a statement from the airline. "In that context one must really question any action that would harm so many soft interests at this time."
Passengers were advised to contact their local Liat airport office or the Liat call centre for flight information.
Liat is owned by regional shareholders with the Governments of Barbados, Antigua, Barbuda, St. Vincent and the Grenadines holding the majority of shares. It currently serves 22 destinations throughout the Caribbean and Guyana, the carrier's only South American destination.
