Low-cost carrier Zest Air has been placed under "heightened surveillance" by the Civil Aviation Authority of the Philippines (CAAP) following a spate of recent flight cancellations. In July alone Zest cancelled over 30 flights, attributing many to "mechanical aircraft problems" and "aircraft situations", CAAP says. "We suspect it's some problem with their maintenance policy. The flight cancellations are affecting passengers - especially tourists," says the authority. CAAP has not grounded the airline, it stresses, but Zest is under "heightened surveillance". The authority will additionally check the airline's maintenance regime to see whether it has been following "normal procedures".
