Finding the right way with the companies which suit you best
As where different flight companies are owned in different countries, so they also operate different from each other. Different standards, and different approaches to a whole row of different things. What is similar across the board is of course the security measures which there are an international set of rules which must be followed.
So if you have at times felt that different airlines treat you in different ways, it might just be because that is exactly what happens. And traveling with an air line which are close to your standards and your cultural values may greatly improve your journey.
