The government owned Solomon Airlines is facing legal action over an apparent breach of contract with an Australian airline.
The Solomon Islands Finance Minister Gordon Darcy Lilo says the airline is now flying its international services using a Boeing 737-200 operated by the Australian charter airline, OzJet.
But the Solomon Star reports the airline has failed to pay for the lease of another plane, an Embraer 170 jet, from another Australian airline, SkyAirWorld.
SkyAirWorld told the paper it is continuing to charge Solomon Airlines for the 76 seater jet, that has been grounded in Brisbane since last Friday.
SkyAirWorld says the Solomon Airlines agreement to lease the plane began in May, for a minimum of three years.
