I would say the salary is on the low side. Western mainscale teachers are getting anything from 11k to 17k per month plus all the benefits you mentioned, but we only travel coach class.

Unfortunately you seem to be having the 'race' salary applied in your case. Ask what a westerner would be paid at the same job and ask them to match it.
