The airline said 186 crew had left in the first seven months of this year, with many blaming family pressure prompted by the incidents.
Malaysia Airlines confirmed in a statement: "Following the MH17 incident, there was a spike in crew resignations but the number has now decreased to acceptable and routinely expected levels".
"Many cited 'family pressure' as the reason for their resignation due to the MH17 and MH370 tragedies."

Abdul Malek Ariff, secretary-general of the employees union, said some crew members were "now afraid to fly". But the airline said it was providing emotional and psychological support to workers.
Speaking to the Edge Financial daily, Mr Ariff also said that crew shortages were forcing staff to work up to 12 hours a day.
The union represents about 8000 of Malaysia Airlines' 19,500-strong workforce.
The two tragedies killed 537 people in total, of which 27 were crew members.
Flight MH370 disappeared in March as it flew from Kuala Lumpur to Beijing. No trace has been found despite a a large-scale search in the southern Indian Ocean. The airline was widely criticised for its handling of the crisis.

The ailing airline is currently being taken private by sovereign wealth fund Khazanah Nasional as part of an expected major overhaul to revamp the carrier.
Khazanah is expected this week to announce a series of restructuring measures including job cuts and axing of unprofitable international routes.
The carrier was already struggling before the two disasters, but has been plunged further into crisis in light of the recent tragedies.
