Passengers affected by a plane malfunction that caused a LATAM Airlines flight to suddenly plunge have reportedly been offered more than $7500 in compensation.

On March 11, LATAM Airlines flight LA800 was travelling from Sydney to Santiago via Auckland when it suddenly dropped, an hour before landing, injuring about 50 passengers.

Ten passengers from Brazil, France, Australia, Chile and New Zealand, as well as three cabin crew members, were taken to hospital.

The airline has reportedly offered some passengers ex gratia payments of between $US1500 ($2298.30) to $US5000 ($7661.02), according to Carter Capner Law director Peter Carter, who has been engaged by some passengers.
