Nope, it's a typo for sure. First officers get 641,000 Euros a month. More if they fly over time, base flying is 20 hours a month.
In a crazy coincidence, 64,000 RMB (The currency of China), would equal about $10,078 a month, which is the going rate, plus per diem. You pay your apartment and food. PS contact the company directly, the brokers will take a slice of about 1,500 US a month and give you nothing. FR
