A friend has a resident alien card, hes applying for his Mexican passport, my question is ,can he fly from American type of airlines to the philippines??
Your friend will need to check with the Philippine authorities as to what their entry requirements are.
H should probably check with the Philippine embassy or one of their consulates here in the United States to see if a visa is required since he will be traveling on a Mexican passport. Once that is taken care of he can travel on any airline to the PI.
