Hundreds of Air Vanuatu passengers have been left frustrated and stranded. 

The airline's only Boeing 737 is grounded in Brisbane while it waits for parts following a technical fault. 

Australian correspondent Donna Demaio told Tim Dower that suggestions are being made as to how this could be prevented. 

She says one travel agent has suggested Air Vanuatu partners with other larger airlines so it can offer more consistent flights. 

She says it's caused anger and anxiety amongst many passengers, with some first learning of the situation on their way to the airport.
