NYP there is many airlines did something that we can't find the true answer it's because they trying to cover their bad habit like race or religion discrimination you just mention SIA but you forget to look at RBA this company do look for F/O some times ago but only special for one who had Australian,New Zealand or British license, you are I believed had a FAA license I had a ICAO standard licence, could you tell tell me what is the difference once we all had over 5000 hrs on a jet and experience flying for airlines, I believed it depend to the person him self to be a good professional pilot, there is bad pilot and good pilot licenses and race got nothing to with it, that is the case for RBA they do believed that those license issued from those 3 countries are guarantee accident free because RBA do not have other reason
